Ebike Cadence vs Torque Sensors - the surprising outcome

[@Area13ebikes]

Which is better? A Cadence or Torque Sensor?

[@michaelhorton6166]

It depends upon the person and the situation. I prefer a torque sensor. It makes me feel like I have bionic legs!

[@davemeise2192]

For me, I like/need the cadence sensor and throttle combination. I've had a serious motorcycle injury so can't necessarily use one of my legs to it's fullest. Consequently I sometimes need to use the throttle to start off from a standstill, sometimes I ghost pedal in order to get the motor assist as my leg won't do what I want it to do. A torque sensor would leave me stranded sometimes. Some days my legs work as they are supposed to and then it's a great day!! My ebike has been a blessing.

[@Certago]

Got a cadence sensor bike without throttle and for slow speeds this isn't great... That said I'm happy

[@HHH8897]

For me torque

[@plozar]

@@michaelhorton6166 I also enjoy the delusional feeling I get from a torque sensor especially for climbing hills :)

[@nolowputts]

Best description I've heard of the differences: cadence sensor = you helping the motor, torque sensor = the motor helping you.

[@rayhoskins921]

I like the cadence sensor because it makes me 60 years younger with the ease and quick pickup from a stop. So much fun 😊

[@PlotShots]

Awesome video! I went down the proverbial “rabbit hole” researching e-bikes and I have finally come up with a very simple conclusion: IF you are a cyclist (i.e. carbon fiber Fuji road bike, Specialized Stump Jumper, etc.) then a torque sensing mid-drive is for you. If you are an occasional cyclist (i.e. single speed beach cruiser), a hub-drive with cadence sensor is for you. I am the cyclist, so I bought a Biktrix FS Juggernaut with a 1,000W mid-drive and I got my wife a 500W hub-drive cruiser. Love this channel, BTW. Definitely gonna visit the shop soon since we live in Sacramento. Cheers!

[@PlotShots]

@DASO_MILITIA I did a "range ride" by getting on the bike trail in Old Town Sacramento and rode to Hazel Ave (fish hatchery) and back. I took my charger with me just in case, but didn't need it. It was 22 miles each way for a total of 44 miles round trip (70 km) and I still had 30% battery life (~15 miles) remaining.

[@hainsrj]

I have a smart motion which has both cadence and torque sensor. You can change whilst riding by a double click on a button which means you can work at the pace you want when you want. I am 85 years old and both knees are completely shot but I can still ride 40kms per day.by varying the sensor and the effort required at any time.

[@timiditta70]

what kind of engine and what brand is it?

[@Frank-mn4hx]

@@timiditta70 Sound like an ION-sytem. That's a smart system. Or it can be a BOSCH.

[@davidrumsey3180]

Smartmotion is a New Zealand designed brand, only sold in NZ and Australia as far as I know. There is a control built into the display labelled "Power" / "Eco" which actually switches between Cadence sensing (Power) and Torque sensing (Eco). Most torque sensors also transmit a digital cadence signal as well as an analogue torque signal, so if the controller is set up to process both signals, and there is a switch that allows you to choose, you can have either. They use Chinese Dapu motors. I am not aware of another bike brand or another motor type that offers that choice.

[@dennisluz6453]

Yeah, please give bike brand with those features. Looks like a good compromise for some people

[@hainsrj]

@@dennisluz6453 the bike is a SmartMotion all their better bikes have the feature. Designed in New Zealand and assembled there but Made in China or somewhere. The one I have is the X-City which is a step through hard tailed mountain bike, now I think the latest is the Neo but their standard bikes also have the feature.

[@MarkSmith-js2pu]

Probably the best explanation of the differences I’ve seen. I’m on a cadence, hub, with throttle and 8 gears. 100 miles a week to work rain or shine on mostly level roads. I use the throttle every time from a stop. I call it my launch gear. Makes for a smooth transition. Doesn’t take much of a hill or wind before ghosting has become a big irritant. I need to test drive a torque machine. Sometimes I want the exercise, but usually I want a 20 minute ride to work without sweating and just enjoy the time on 2 wheels.

[@siphillis]

Torque sensor with throttle seems like the best of both worlds. If you want to relax, the bike can do all the work. If you want to get a workout in, lower the boost and start peddling.

[@jeremyporter1991]

Thanks for the video. This was the best video I’ve seen clearly explaining the difference between cadence and torque sensors. Before this I didn’t truly understand the difference, but now I do.

[@jonspeak2807]

As an older person, my vote is for cadence sensor!!! With two bad knees and two replacement hips, I'll take the easiest option! However, ebikes had a BIG impact and my ability to get around! I pedal 99% of the time! I got into ebikes because I had given up on bike pedaling Forever! I might even be ready for one of those torque sensors one day!

[@BullToTheShit]

> *"As an older person, my vote is for cadence sensor"* Hear, Hear! I can participate when I like, and I can _Ghost Pedal_ when I like (which is most of the time). I love having the choice.

[@rickiejacobs5910]

I have several bikes but can’t ride them anymore do to Congestive Heart Failure. I understand that E-bikes that help with peddling, can help you slowly get back into shape. Also with a Throttle if you get tired you just stop peddling and let the motor take ver.

[@dennisluz6453]

It is quite simple: there is a significant divide between older people (and often older people with some physical disability) and younger bike riders who like the challenge of physical activity with torque sensors. The former, I suspect, prefer cadence sensors for obvious reasons and also because they mostly use their bikes for easy, reasonably flat terrain, and when throttle can come in handily when they are tired. Yes, yes, pedaling is good exercise, I acknowledge.. As an older person who has had back surgery I was considering a eBike with hub motor and torque sensor (plus front fork suspension and hydraulic brakes) but now I think that maybe a cadence sensor with throttle may be better for me because of my physical limitations and my preference for riding over paved streets or fine packed sand trails (no gravel or hills). It could also save me $$$ going this route.

[@jonspeak2807]

The longer I ebike, the more I pedal, FACT! Ebikes are definitely beneficial to older riders. Whenever I get crap from the SPANDEX ARMY, who paid more for their bikes than I did mine, I have to laugh! They mean well. You don’t need spandex and watermelon calfs to enjoy and benefit from biking! At the same time, I’m enjoying it so much I want to make it my primary form of transportation.

[@Heretowatchstuff]

My first e-bike was a fat tire bike with a cadence sensor. It was a blast. I just got a new road e-bike with a torque sensor. I absolutely love it!!! So smooth!

[@rudebuddha4895]

Thanks for this. I bought an Aventon Aventure (one). I didn't get to use it this year so it sat. Next thing I know the Aventon Aventure II (two) is on the market. I had originally felt buyers remorse for now owing an "older" version, without torque sensor, since the new model has it, as I'm sure you know the earlier Aventure has cadence. After viewing this I'm happy with my earlier model since you covered the pro and cons. I feel my riding style, as someone commented, lends it self to the cadence. It's not just a case of one being newer and better as I originally thought.

[@Jim.e.Whitten]

I like the cadence sensor, as a older guy that hasn’t ridden in a long time it works for me. I like the throttle and ghost peddling. I still get plenty of exercise…but I also can still make it home without killing myself on some of the hills.

[@richhowell6874]

I like the cadence sensor bike for the overall control I have. I start out with the throttle and adjust PAS and gears as needed, giving me the effort level that suits my 75 year-old legs. The one plus of the torque sensor is on trails where one wants the bike to respond in realtime. The lag of a cadence sensor can be a liability when riding up and down or over roots and rocks.

[@wendygerrish4964]

Ah! Great explanation. I guess while riding uphill in lowest gear..and you just can't push the pedal anymore the cadence sensor would see no demand, that is where the throttle would have to be utilized or..cadence override. Impulse power Scotty.

[@richhowell6874]

@@wendygerrish4964 As a matter of fact, Wendy, I ride up two steep hills on my ride to the gym and back. The throttle is very convenient at the steepest point for a quick burst of maximum power. I ride for exercise, so I try to use the minimum PAS most of the time. When you ride the same roads daily, after a while you know what PAS levels and what gears you use for the whole trip. Impulse power is a great idea... for the VERY steepest! We have one such hill where I live.

[@wendygerrish4964]

Sounds like my driveway. Thanks.

[@erikkpritchard]

I also like cadence sensors and I ride trails a lot. A responsive cadence sensor gives me good control and makes getting to the trails a lot easier! I rode a Trek Powerfly (torque sensor Bosch) up to a trailhead and I was exhausted before I even started the trail.

[@richhowell6874]

@@erikkpritchard I understand what you're saying. I've had a similar experience here in Nevada City riding up a long (3-4 miles) hill to my favorite trail on a 40nm/250W mid-drive. The bike was great on the trail, but exhausting for this old guy to get to the trail. By comparison, my 24", 70-80nm/750W Bolton has no trouble with the hill, but lags just a bit with the application of power, going from not-pedaling to pedaling. If I wasn't so old, I'd buy a 750W mid-drive to add to my stable.

[@tomgooch1422]

Thanks for the great channel! In 350+ miles of hilly local roads, I've gone from factory settings where zero position = no power, and with a crank throttle, to zero position = 25% power and a thumb throttle because of very steep hills in my area. When the transition from steep downgrade to steep upgrade is within a few feet, a thumb throttle is key to instant access to full power, regardless of whether it's cadence or torque. It's an awkward moment of discovery that you've stalled and your ebike does indeed weigh 70 pounds as you're absentmindedly falling to the pavement. BTW, don't worry about the fall...it's the stop that hurts. I also installed a dropper seat post, dramatically improving the safety of stopping at intersections. I loved the full leg extension of the fixed position high seat before discovering both my legs had shortened by four inches when I had to steady the stopped ebike.

[@stephenwilliams4406]

For Seniors or those of us who might get a little tired before heading home, Cadence sensor is the best way to go. Extra power when you need it.

[@maschwerer]

Torque sensor is much more natural to pedal. Feels like bionic legs that amplifies my efforts. You can raise/lower the boost based on your mood. Works great and gives better bike control.

[@dennisluz6453]

Overwhelming consensus. However it also costs more.

[@BillTheHawk]

Kyle, the Biktrix you sold me has both Torque and Cadence sensors! Plus a throttle. I love it.

[@keithdunlop2027]

I was going to say, I thought I saw a couple of manufacturers advertising both in one bike!! This seems like it would be the best combo to me (as long as it had a throttle)..... Kyle, you dropped the ball not addressing the combo pack... I would not be surprised to see more bikes going this way.

[@billclark8241]

So you mentioned that people should ride the bike first to see the difference so they can make an intelligent decision that suits them best. I'm in South Florida does anybody know if there's a place anywhere in Florida where I can go and ride a few bikes before buying one?

[@dennisd7451]

The cadence is much better for an older person, especially if your pulling a trailer, I ghost pedal mine (using no leg muscle) until it reaches 17mph, then I Coast till it reaches 12mph, back and forth extending the battery life, while pulling a burley nomad cargo trailer with 200 watt 9bb solar panel on burley stock rack, modified with extra holes I drilled in the tilt adjustment push button upper support arm 1/2" aluminum tubing. It comes with two holes for the spring loaded buttons, flat position or raised position about 45degree. I added two more holes in between these simply drilling new holes , so I can follow the sun, example flat, 20,30,and 45 degree positions to receive more solar watts while I'm riding that's especially useful when I'm riding SOUTH. RIDING NORTH IT ONLY LAYS FLAT. But I also added a East, west tilt bracket attached to the burley stock rack using electrical pipe clamps which comes with a carriage bolt to tighten around the 1/2" burley stock rack, modified. I carry a 7lb 120v ice maker running off my 11lb Bluetti, in one hour I get about two quarts of ice to fill my Jumbo WAWA INSULATED PLASTIC CUP WITH LID AND STRAW TO THE TOP, APPOX. 8 CUPS OF ICE WATER. This I carry in the front of Trailer easily accessible when I stop riding for a solar chage break and ice maker running time could get 1/3 of the ice in a 20 minute break. The extra bite battery is always charging at either 107 watts or 300 watts depending on which battery pack I'm charging, the stock 48/15amp or my new 48/20 amp battery purchased by LEPNERYEE Hailong E bike battery 48v/ 20 amp for a 0-1500 watt motor $316.00 Amazon in shot supply. I'm 200lbs, my trailer fully loaded with camping gear pernair bags loaded sleeping bag and tool bag above large front head light I'm pulling 450 lbs. Mounted a motion detector brake light to the back of the solar panel, which is also an alarmsystem with very loud alarm sounds if even bumped a little, with turn signals and separate control switch mounted on left side of handle bar close to the rubber grip.. Perfect set up for long camping trips, especially if I sleep from 10am to 4pm. During which time I'm getting around 170 watts per hour solar which averages about 1200watts incoming per day , at 65 years old the batteries outlast me. It's almost like having FREE POTENTIAL MOTION..Lol. in Florida it's very flat and to hot to ride between 10am and 4pm anyways, I'm in no rush being retired and just living the life at my own pace . I do use flat out in all my 20/4" and 26/4" tires with extra tube's for trailer tires 16" at 50 lbs of PSI. HAVE FUN SEE YOU AT TGE PIT STOP..LOL

[@lylejenkins9374]

Great explanation! My wife and I are on our 4th set of e-bikes. The first 3 have been folding with cadence sensors with throttles. We now have Juiced RCS's with a combo Cadence/Torque sensor which are mounted near the rear hub near the motor. So far we love the more natural feel of pedaling these. They also have thumb throttles which we use to start out and to add power going up hills. I have also ridden mountains bikes with mid motors and crank torque sensors. These are extra fun but I still prefer having a throttle on E-bikes.

[@lenbeedle]

Chiming in from south western Canada here. I can see the argument for either. I'm just beginning to learn the concept of these pedal assist assemblies. Mine is cadence. I think I do prefer that despite not experiencing the difference. As a man in his mid 50s and not being hugely athletic, I like the safety net of having the throttle if I need it and not having to necessarily work hard to activate the full potential of the motor. I'll even touch the throttle off the line just enough to get me into pedaling mode.

As a scandivian possible buyer of a Electric bike, this is an awesome video… 👌👍

[@misterg609]

I had a 750-watt hub drive cadence sensor bike that could go 33 mph with little effort for long stretches. I now have a 1000-watt Bafang Ultra mid-drive torque sensor that can get as high as almost 40 mph but I can’t maintain that speed for long as it is too exhausting . So with just PAS I could potentially cover more ground quicker with my old cadence based 750-watt hub bike, although as stated, the torque sensing 1000-watt mid drive feels more natural. As Kyle mentioned , both have advantages, and while I prefer the torque sensor, I do often miss cruising 33 mph while essentially ghost pedaling.

[@wendygerrish4964]

Thank you for that. Explains clearly an advantage of a cadence bike under certain conditions, and the fun of ghost pedaling.

Thanks for the video.. definitely a subject that needs clarification (especially when you have ignorant or dishonest people trying to sell cadence sensing bikes as having a Torque sensor... which I have seen). My personal preference is Torque sensing plus a throttle, I like the feeling of being rewarded for my extra effort, and I like being able to ride technical singletrack without sudden surges when the power kicks in. I am only in my 60s and have a bit of fitness left.. but I can see that in 10 yrs time I might be thinking that cadence is the way to go if my strength and fitness fade.

After viewing a lot of KZbin videos this particular day, 1/18/23, I am very interested in the Aventon Level.2 ebike. Being a Class 2 ebike having the torque sensor with hub drive it still has a throttle, which I feel would be the choice, I would be most happy with having.

[@2bitProjects]

Thanks for the video, the last bit was the gold, the Bafang that does it all. I am a throttle user so I have to have it, but when I pedal I would love the more natural feel, definitely better for an actual MTB rather than a casual rider., I am somewhere in the middle. Sounds like cadence will exist on the entry level bikes and is the right choice for those people and the torque sensor exists on the higher end bikes and the right choice for those people, hopefully this video will help those right in the middle where there is some grey area, thanks

[@georgekrpan3181]

Cadence sensor with throttle works brilliantly. Use the throttle when starting out from a stop. The delay time of the cadence sensor on my bike has very, very little delay.

[@genemcloud4114]

I have been researching this topic for some time now and this is by far the best explanation I have found. Although I have not ridden a torque sensor e-bike yet, I’m pretty sure my current cadence bike is still going to be my preference. The reason is my age and declining strength. I’m 76 and just don’t have the stamina I once did. That being said, I think the cadence sensor is likely the best option for me. Again, thanks for an excellent explanation!

Thank you so much, this video helped me so much as I am planning to get rear hub conversion kit and i was unsure of what each sensor is like. You wouldnt believe how relieved I am now, May Jesus be with you, God bless.

[@Zuckerpuppekopf]

For elderly riders, a throttle is a must, and this is why: connective tissues, tendons and ligaments, and cartilage menisci become much more fragile to high stress (think high torque), so it's not uncommon in benign and completely unexpected situations for something to suddenly "give" (or start hurting severely), and in bicycle riding this could be knees or or leg muscles. Usually if one relaxes for a moment and adjusts the vectoring of the force on the thing in the "give" state, it returns to normal, and ordinary use and pressure can then be applied. The highest likelihood of a sudden pause like that in riding will occur almost exclusively when at a dead stop and subsequent start when forces on the rider's legs and joints are the highest. Stops and starts, unsurprisingly, are also typically at traffic intersections. A bicyclist wants to accelerate smoothly and ride in the most predictable and straightforward way in a traffic intersection for obvious reasons: it's dangerous to suddenly pause or wobble in the middle of an intersection as one is making a turn or even going straight. I don't care how much AI is layered onto a torque or cadence sensing motor: it cannot ever predict the unpredictable. But usually the elderly person themselves can SENSE when these events are about to happen. That forewarning can then be used by the elderly person to force the ebike, via the throttle, to take on more of the load when that person knows they must suddenly reduce the load or torque in the middle of an intersection to adjust their legs or body. So based on your description of torque vs cadence sensing bikes, cadence sensing bikes with a throttle makes vastly more sense for elderly riders. If a bike is torque sensing, it will have no clue why someone is reducing the torque on a crank, whether it is deliberate or due to sudden unexpected leg discomfort. Of course, if a throttle is added to torque sensing bike, which as you say is not common now, then that could potentially be as good or even better than a cadence bike with a throttle. The key however, for elderly use, IMO, is the throttle. The lack of a throttle on torque sensing bike is an absolute deal breaker for many if not most elderly.

[@readysetdrone]

Love this video! Thank you. I have been getting into eBikes lately and have ridden a torque sensor (Specialized) bike once, but only own cadence sensor bikes. I really would love to see a low priced, high quality torque sensor bike.

Just to confuse the subject, my Juiced Bikes HyperScorpion has both a cadence and a torque sensor as well as a throttle. The cadence sensor is always active, but the torque sensor can be turned off in the settings menu. I like riding with both on. It feels good to me to be rewarded for riding as hard as I can.

[@robertlyon4101]

I have a Juiced bike CrossCurrent with both torque and cadence sensors and really like this setup as it feels very natural with a smooth power delivery. It’s a class 3 bike so also has a throttle. A friend has a Santa Cruz mid drive with torque sensor, nice bike, but it can’t keep up with the CrossCurrent as being a class 1 bike it has no assist over 20 mph. I suspect the Santa Cruz would be strong on big hills though, where the extra torque of the mid drive and the low gear potential of the 12 speed cassette would be a big advantage.

[@SanDiegoElectricBikes]

Level 3

[@jamesnewsom5899]

I drive rear hub 750W, cadence sensor, twist throttle. 7gear shimano, pretty typical. They all work so seamlessly for me that I can adjust my effort level as quickly as I need, I can't see a need for torque sensor, although when first looking at bikes I thought I would really want a torque sensor. I guess if I was an avid heavy duty mountain biker I might want the torque sensor for instant response. Other than that, perhaps if I was a serious road biker, competitive level , torque sensor would probably also be nice. But for everyday commuting, fun, all around exercise traveling, even light trails, hills , gravel, snow, mixed conditions my cadence sensor with twist throttle is a perfect fit. When I need to cross busy roads quickly, just twist that throttle and get across quick! And then let go and let cadence do the work. My only complaint would be my gearing which doesn't allow my pedaling to help beyond about 22 MPH, just ghost pedaling at that point. But since most of my riding is done between 15-20MPH it is not an issue.

[@danimayb]

I have a 1000w hub and 21 gears, That extra large 3rd sprocket on the front defiantly helps at higher speed, But even then, When I go past 25 I start losing momentum. That's where the throttle comes into play though, It will take me to my top speed of 30-32 mph (depending on voltage level), plus the fact I use it anyway when cruising, So it doesn't matter to me.

[@polok890]

Perfectly stated. Cadence with throttle is just the right away for ebikes

[@brianstanfill2114]

Cadence On my Himiway cruiser, I ride mostly on single track trails and can put in the effort I desire until my legs fatigue and then ghost pedal while the motor does far more than me. Within moments I can start to exert more force with my legs and then I’m helping the bike move along with the motor. Your explanation was fantastic and helped me appreciate what’s going on behind the scenes with both types. For me (older man, poor knees, fit, desiring a degree of exercise), the way I need and desire to ride, the cadence sensor with throttle control is optimal.

[@fredjin4011]

I debated a mid drive Bafang (cadence) or Tonsheng(torque). I normally ride a full suspension mtb and wanted to still have a good workout riding. I choose the Tonsheng (torque) and super happy with my choice. I still get a great workout and go twice (ok maybe 40%) faster And clean many hills and features that I couldn't on my regular ( I like phrase 'acoustic') mtb. I also agree with others that describe a torque sensor to feel more like you have bionic legs rather than just having the motor do the work for you. On my new bike I still feel like I am riding a bike and not a scooter.

[@krix0043]

a torque sensor Bafang Ultra would give you 1000-1500W and 160Nm with reliability and quality. Bafang hub motors combined with a torque sensor would give you also a lot of power. Yet, you chose the cheapest? solution. Don't know. But probably the least weighing solution at least.

[@cblackall21]

This is a very useful but depressing video for me. I just purchased an ebike from a reputable brand and it comes with a torque sensor, and yes it works exactly as you describe; that is, I have to invest quite a bit of pedel energy to get any speed out of it. The thing is I have osteoarthritis of the knees/hips and so downward peddling pressure causes pain after a short while. My previous two ebikes had cadence sensors which only needed me to lightly turn the pedals over to get accelerate and cruise at top speed (25kpm here in Australia). Perfect for me. Because I didn't know the differences between cadence vs torque Sensors I blindly walked right into purchasing a new bike that I probably won't end up using. The vendor who sold it to me is already trying gaslight me that I'm the one with the problem, not the bike. So pro-tip: if you have osteoarthritis make sure you purchase an ebike with a cadence torque sensor. Any tips on how to retrofit the make ebike to have a cadence sensor would be appreciated. It has a Panasonic controller and drive.

[@MHH3180]

I have found that the 'power levels' are actually more like 'aiming speeds', as in speeds you might set a cruise control to. So I tend to find myself pedalling at or near those 5 different speeds - I can go faster or slower by pedaling harder or lighter, but I tend to end up at 5 particular speeds. I have ridden a torque sensor bike too, and with that, it doesn't care about speeds (below its speed limit) it just feels like you have bionic legs at ANY speed. It took me a little while to get used to how to control the cadence sensor bike, off road for eg, I have to turn the power setting down otherwise the motor is trying to get me to too high a speed for the terrain ! You just don't get this with a torque sensor, based on my riding of only one sample, I admit. It may be that my particular make of cadence sensor motor (Yose) has aiming speeds, other makes may do it differently, and so have a different feel when riding.

[@erikkpritchard]

I can confirm that different hub motors manage power differently. On my Radrover Bafang PAS meant power level, not speed. As expected a low PAS simply delivered less power, and higher PAS gave higher power. I now have a Linghui hub (Paselec GS9) and it behaves very differently; basically PAS modulates power to manage speed. So I get nearly full power until I reach the target PAS speed, or as you said "aiming speed". PAS basically sets cruise speed.

[@curtwuollet2912]

I like a cadence sensor with KT torque sensor simulation. Basically, it's power control rather than speed control. But, a full time throttle is a must.

[@sliderule5891]

Excellent, thanks for explaining this subject so clearly and the demonstrations.

[@JeremyMcCrearyTechnicalLEGO]

Nice explanation! My 2023 ebike offers the very last combo mentioned -- torque-sensing plus an overriding throttle. Its rear drop-out torque sensor can also detect when you're pedaling. What my motor control system does with this added info, if anything, I can't say, but the power delivery is VERY smooth and natural. Plus, the throttle delivers instant full power on demand in all PAS levels above 0. Sweet ride. Some ebikes offer yet another option -- sensing of both crank torque and crank speed (not just pedaling or not pedaling). You could call this power-sensing, as rider power input is proportional to the product of these 2 measurements.

[@hypnomeditatescape3212]

Kyle, thank you for the video. This type of content is invaluable for an ebike noob..

[@Area13ebikes]

Happy to help!

[@rgeraldalexander4278]

I have both, and like torque sensing with a throttle.

[@mattc825]

The rental e-bikes in Europe such as Lime were like that. Felt very natural. I was surprised they were only 250 watts because I kept up with traffic in Paris!

[@279Auto]

My next bike will have torque sensor with throttle. I like my RadRover, but I'd like it better with torque sensing. With the stock motor controller, the delay starting off was often a balance issue for me. It is much more ride-able with your motor controller installed, as the delay is hardly noticeable, but still has more power taking off in other bike traffic or people than I feel control with. There are not a lot of level trails around here. Can't wait to get your Bolton Air Forks. Any idea when they will ship to you?

[@klumze9911]

I had a hub motor with a cadence sensor and my new bike is a mid drive with a torque sensor with a throttle. I prefer the new bike setup.

[@henrychinaski]

What bike did you get?

[@jonnysokkoatduckdotcom]

Very interesting. This video was very clear. And cleared a lot up for me. Thank you.

[@jeffarcher400]

I'm very light and not sure I weigh enough to fully activate my torque sensor. On long flat rides the motor shuts off at 18 mph and it's supposed to get to 20. That said it's super smooth,quiet and climbs stairs confidently. Nimble in rock gardens but you have to time the pedals not to hit. It's the Brose. Power through the chain means wear and expensive parts. If the chain or derailleur breaks you're stuck. It meters power in teaspoons and has incredible range. The Bafang is another beast entirely. At high settings the power comes on like a spastic light switch and will eagerly launch me into trees,rocks and pedestrians. Sometimes the brake cut off fails and it's burning out while I bull wrestle it under control. Almost yanked my arms off when the brakes wore out. But the throttle is magic and makes it so moto you can't stop riding. You can hold the nose up going off little jumps and do power pivots roosting. Also able to power through turns where pedals would hit the ground if you had to pedal. Top speed is 30 plus but you're dumping energy in buckets and have half the range. All that power eats chains and sprockets. The power doesn't seem as hooked up and tractable but skittery. It's exciting but more exhausting than the smooth Brose. Bafang is living at the pitch that is near madness. Also started way back on the cheap China 1000 watt hub drive and it is amazing. Truly a magic carpet ride with shifting, pedals,chain all not required. Break a chain and keep on going. Parts never wear out. Accelerate from a stop to eye watering seamlessly. Burn out into thrust like an automatic transmission. I ignored the rear gears and used the three front for granny,cruise and overdrive. Sadly it had lots of unsprung weight and got flats sometimes several times a day. I think it blew from speed alone at times and the tube was shredded. Changing flats with the weight,wires and brakes destroyed my back and I never went back. Someday I will and do it tubeless but that had just come out and I didn't want to spend the money. I spent more in tubes and patches. Tubeless rules. My friend had the Sur Ron and I could keep up with the Bafang not with the Brose. He couldn't lift it easily and got stink eye from hikers and horse riders. Never any vibes on the more bike looking rides. They're all good for something in areas the others are weak.

[@markstewart9641]

You described it very well. I for one like the cadence sensor much better.

[@SimonHollandfilms]

good description... i find cadence sensor kicks in as soon as a magnet passes the sensor....on gravel it can throw you off.

[@rossg9363]

I used to really enjoy your channel Simon, i dropped off after i found out you where not a real professor in your comment section one day, i felt like i had been conned... you don't even need that title, your very good at what you do and are a nice guy to hold your own! Anyway all the best👍

[@johnharper810]

I hit a patch of stones at a corner intersection on a busy road. I lost control and lurched into the street. I am lucky that the cars stopped before running me over. My high power cadence sensor bike propelled me at the speed setting of the pedal assist. I believe a torque sensor would give me greater control over my speed. I will switch to torque assist as soon as I can pay the price for it.

[@markdennes]

Torque sensor and throttle helps you escape accidents with people and cars here in San Francisco!

[@elainemiller4192]

Juiced bikes have both. That's my favorite set up.

[@vladi41thbirtday]

Great video. It couldn’t be clearer. Great job.

[@ericd.6368]

As a person getting back into biking at the age of 60 after a 25 year absence, the cadence sensor was the best for me. I bought the Aventon Aventure after they dropped the price $500 and I am convinced I bought the right bike for me. Is there a torque sensor in my future? Possibly. But right now I am loving the bike I have.

[@mc8542]

Thank you!

[@Area13ebikes]

You bet!

[@kmemz]

I'm ordering a torque sensor for my bike if I ever get the chance, but I'm *going* to find a way to keep my thumb throttle. No exceptions, even if I have to splice it together somehow. For a front hub motor like what my DIY eBike is, losing traction on that front wheel is not an option, and cadence sensor PAS gives me massive issues with that, to the point where I had to remove PAS entirely for now due to crashing as a result of front traction loss on loose surfaces. I'm going for the best of both worlds, and nobody's going to stop me.

[@SanDiegoElectricBikes]

Mid drive motors have the advantage of gearing... hub motors can operate independent of the gearing - can even go with no chain. Mid drive is very natural and work best for technical riding, hub drives deliver more power to the wheel but the weight bias to the rear wheel makes them a poor choice for serious mountain bike riders. Hubs are best for commuter and casual trail and street riding. My opinion. Thanks for creating and sharing this informative content. NOTE: no throttle... with a throttle it is a Moped, not a bicycle. Period.

[@kevinmathews1320]

THANKS for this informative video!! So, I just learned about what is ... well... "a little off" about my just unboxed Velotric Discover-1 Ebikes! Don't get me wrong, these are a great value but they do use the cadence type sensors, and as I discovered, it can be DANGEROUS!! What I learned on my first test-drive - uphill on a 1.5 mile climb, is it works great, the levels of assist are definite and I did see that "ghost pedaling" works! Then i stopped to check little things, and on I went. Foot on the pedal, rotate... aaannnnd WOAH!!! The pedal assist was still at 4, and when the cadence sensor said move, it almost went out from under me!! NO LIKEY!! Well, honestly, I think it will just take some getting used to! One other thing I found, these bikes will not move with just the throttle! They need the cadence input, then the throttle will slightly add to that - sort of. May need some tuning... Wish I knew this info!! Next bike will likely be a torque sensing with throttle!

[@DriverJ-N]

well not moving with throttle isnt a cadence sensor problem.... juiced ripracer for example can use throttle from a dead stop and its cadence based and from the video if u moved the pedal with a torque sensor it will also move pretty quickly but not as fast as cadence...

[@DanaChase]

I have ridden e bikes but don't own one, but my idea is when I buy one, I want a torque sensor bike with no throttle. I ride a regular bike now and all I want an e-bike for is to help with the hills but if I have a throttle, it might defeat my goal of riding a bike for exercise. I want the assist in direct relation to my effort.

[@WildBlueWanderers]

I think I would prefer the torque sensor because it rides more like a regular bike. With a throttle to override when I don’t want to have to pedal is hard. I have been looking, but have not written any yet, and that was one of the complaints I saw was that the cadence sensors were jerky and just take off on you.

[@CenturyBatteriesAbby]

We have had a few elderly customers with health or knee issues that thought they would never ride a bike again, thanks to E-bikes it has given them their freedom back. Having that throttle and reduced effort needed to pedal is a game changer!

[@brudd5021]

We have two ebikes in the family. Both are 4" fat tire, all-terrain bikes with hub motors. One has a cadence sensor and the other has a torque sensor. After riding both bikes and measuring calorie burn with a smart watch, the torque sensor bike burns significantly more calories over the same distance. I also noticed the battery drain was slower with a torque sensor compared to the cadence. I prefer the torque sensor because of the exercise benefits, plus it's faster. If I want to just cruse I find the best gear for the least effort required. The cadence sensor bike is a solid bike, and my daughter rides it now.

[@eggy1962]

Good video well explained, i have cadence with throttle option, in fairness i have got used to it now, my sis has similar bike but hers has torque sensor….yes its smoother but was £500 more

[@davidwooten3430]

I reprogrammed my bafang that only detects by pedaling to give power based on the number settings. I can max at 20% help at 2 of 9 for instance without getting full power to a certain speed.

[@chriswolff5459]

I love my Tongsheng mid drive with torque sensor. It also has a throttle for taking off from a complete stop, which is great to save the ol' knees. I transfered the Tongsheng to another build from my recumbemt trike. I think haveing a T.S. set up is better on a two-wheel bike because when I stand up and crank on the handlebars, it really feels great! However haveing switched out my TS kit for a cadence kit I am very disappointed riding my trike now. I bought a bottom bracket torque sensor, and found out later that this systen is not compatable with the controller that came with the Chinese kit.

[@charliegregg9447]

Nice job explaining pedal assistance.

[@retirednow2]

I have Tern HSD S+ and a Luna Eclipse. The Mid drive Bosch motor in tandem with the Gates belt system on the S+ is excellent. But you have to pedal and sometimes hard. I enjoy the hard riides so for me its ok. The LE is a Bafang Hub motor with the Gates belt system. I am a tad dissapointed. Lots of ghost pedalling and not a lot of speed control without some throttle. If Tern made an S+ with fat tires I would buy it. Thanks for your great review!

[@frankthecat2089]

Super helpful, I am gonna get the Aventon Soltera 1, I am 60 and want to control the motor when i tire.

[@h3h3eot]

I have both and for me the torque sensor wins every time because it’s more enjoyable for me, and feels very natural.

[@FirstLast-ml7yf]

Throttle only with cruise control for the win. Most intentional modulation whether eco-miling or taking off quickly in an intersection.

[@ericb.4358]

Fortunately Dave, the owner of E-CELLS bikes, has changed his top bikes over to torque sensors. It offers me better control at slow speeds than my buddy's cadence sensor version of this bike. AND these bikes also have a throttle. BTW, my e-mtb has TWO hub motors and thus 2 wheel drive and it has 9 (NINE) pedal assist levels. It's a "HUMMER" version of an e-mtb.

[@robert71457]

I like that AVADOR! but I'm attached to my thumb throttle and hub drive!

[@lewchaney2138]

I know my comment here is a little late on this video but I'm relatively new to e-biking, and dealing with wanting to pedal along with my hub motor only to realize I mostly can even pedal fast enough to add value I now have a question about an obvious short coming of all e-bike controllers and displays. I've recently ordered new front and rear gear sets for my 24 speed mountain bike to allow me to give pedaling value back to my motors energy use. As I researched the gearing ratio options, all knowledgeable bike riders recommend shifting decisions based on your pedaling cadence RPM's. There are even cadence RPM monitors marketed to bikers to assist with shifting decisions. So here's my question, why do none of the e-bike controller displays show cadence RPM? It is very important information that could be displayed, but is totally overlooked.

[@MarkizVonSchnitzel]

For commuting, for someone getting from A to B, I much prefer the cadence sensors from everything said. Some day I might feel like shit, and don't want to pedal hard. I want to reserve this decision for me. But because I am in EU, most such bikes are illegal anyway.

[@michaeljohnson1413]

Thank you for that very useful information.

[@Area13ebikes]

Glad it was helpful!

[@bodysurf100]

The only e bike I have riden so far is a torque sensing no throttle bike. While it was a blast to ride I'm thinking that adding a throttle to that bike would be a plus. Have to ride some more bikes before deciding which way to go.

[@fredremer2993]

I prefer the cadence because I'm 69 and if I'm too far from home I don't want to have to use a lot of leg power to get home but still get the exercise I need.

[@johnrhopkins]

We are just now shopping for our first ebikes. We live in a very hilly area so I'm looking for a mid-drive torque-sensing setup. We are planning to move to a very flat area (Yucatan Peninsula) and will likely switch to a hub-drive cadence-sensing setup.

[@Edwardjonez]

I love your clear and concise speech and statement you sold me on a Cadence system when I wasn't sure what was best for me thank you for your most excellent video. : )

[@Sleeli25]

this was SO helpful, great explanation, thank you!

[@fluidray]

Thank you for the explanation. My wife has a cadence sensor hub motor. I purchased a mid mount torque sensor without knowing. I found that I could only get full PAS when I was pedaling harder. Surprise I was doing a lot of "ghost" pedaling before. Kinda disappointing but I'll get a better workout. I have only put a few miles on so far.

[@mysteryprize]

One thing I found very disconcerting with cadence sensor bikes is that when you try to gradually ease off on the pedaling, knowing you have to stop soon, it tends to think you still want power (because the cranks are still spinning). So instead of cruising at a steady speed you find yourself accelerating. I'm sure there are strategies to avoid this, but it's a noticeable part of how torque sensor systems feel more natural (more effort = more power) versus cadence (power provided by the motor is somewhat disconnected from what you're doing as a rider).

[@tedwalker1370]

This is something you will get used to. I pull my brake lever when this happens and it stops acceleration immediately. You might try that. Just pulling the lever enough to disengage the motor.

[@polyrhythmia]

Bought a Kona Rove with hub motor and torque sensor. Acceleration requires more torque on the rider's part. Also, more effort is required on the hills than with my previous hub motor with cadence sensor, mainly long steep hills. Normally, I find myself cruising at 20 mph, and what's cool is that my speed doesn't change much with wind direction. Ghost pedaling is not my aim; my aim is to get a workout if I want it.

[@PlayFloyd_IN]

Superb explanation, thanks a lot. 🙏

[@NguyenTran-eu1pw]

It’s really dangerous when you stop to wait walking light on. If not holding brake tight, your bike moves instantly with torque sensor

[@chuck_howard]

I want the most possibilities to choose from. I may want to pedal hard or soft. I may be stopped at a light on a hill and want a throttle to help me start out. Limited to "push hard or no extra power" is not for me. I have rear drive, cadence sensor, and full throttle. Works the best for my riding style and terrain.

Both cadence and torque would be nice. I carry groceries in plastic bags that hang from handle bars. Sometimes I can't pedal. For just riding I'd love the torque.

[@uvwuvw-ol3fg]

Hard to avoid any cognitive biases but wasn't hanging anything on the bars a bit dangerous since the right size item in the bags can suddenly get stuck in the fork resulting in FOOSH injuries? Not the most frequent thing talked about.

[@alexrawls7407]

Cadence sensor is nice for those who understand some simple re-engineering to convert or bypass the pedals entirely
