E Mountain Bike Motors Explained | EMBN's E-Bike Fundamentals Part 1

[@embn]

Which do you use?

[@udaysapra8821]

Electric Mountain Bike Network none of these they take away the whole point of the sport

[@Hunter_Bidens_Crackpipe_]

Bolt on currently, looking to get Specialized

[@kevinargust3694]

Yamaha syncdrive sport. Three power modes ECO NORMAL POWER

[@embn]

Well, that's your opinion. Obviously it's not ours! E-bikes add a whole new dimension to the sport but they're not for everyone just yet. Happy riding!

[@embn]

Nice!

[@michaelcrawford2726]

pw-x is the best motor out right now hands down. tried them all, the pw-x is thin/light smooth and powerful. easily keeps you at max speed (20mph). 1k miles on mine so far 3 months, only complaints it is on loud side and no walk mode other than that love it.

[@Biffo1262]

I have the Bosch Active Line and unlike the CX I haven't noticed any drag when assist cuts out. There is a little drag at lower speeds with assist OFF but that disappears with the correct use of years and increased speed. As an example, I'm 70 years of age, suffer spinal disabilities and I am also in heart failure but I ride my ebike 80% of the time with the motor OFF. It's a Raleigh Motus Hybrid tourer not a EMTB but all the same, the Bosch Active Line is very impressive. Also, it's silent as far as I can tell. Range is outstanding. My local terrain is pretty flat and I can get up to 100 miles on a single charge the WAY I RIDE IT. Others who want an easier time will get less. I went out today and as a test I used the motor over 25 miles on undulating roads and had a projected 27 miles remaining range plus the 5% reserve so even then 55/60 is easily attainable. It is definitely not a power hungry motor which for me was a big selling point.

[@DerekLHays]

This video is exactly what I was hoping for so thank you guys! When comparing the system as a whole (weight, power output, app, de-coupling, etc) it appears the Specialized system is the one to buy (which obviously means a Specialized eMTB). Personally I have been leaning towards Specialized and Haibike when I finally purchase an eMTB. I'm really excited to see the PowerTube from Haibike later this year. The integrated removable battery is without a doubt the best way to go, as opposed to the batteries that are externally attached to the downtube. The Jam2 with internal battery and additional external battery is very enticing, also. It is very exciting to watch this segment of mountain biking evolve and grow.

[@davidbayley5194]

Steve,,, (two years later) you said your lines with out a Hick Up... Well Presented...Cheers

[@filipcoenen6436]

I have a Focus Jam2 plus with shimano motor. happy with it.

Excellent Steve, really enjoyed the programme. love my bosch Gen 4😁👌❤️lots of love from me😂😂👌

[@HEIPPI]

I don't own a e-mtb and don't see myself buying one any time soon but these videos are really interesting and a good way to learn about the ever evolving technology in the bikes! :)

[@embn]

If buying one isn't for you, try and borrow or rent one for a day. It's a different experience on the trails for sure.

[@Mr.ZiggedWhenHeShouldaZagged]

I agree, with both of you, so much fun but I don’t I’ll ever own one

[@HEIPPI]

Electric Mountain Bike Network I’ve been planning to actually! We have some awesome winter trails here in Finnish Lapland!

[@embn]

That sounds awesome 👍

[@emtbtrailrider539]

HEIPPI stop being a wuss and buy one, money well spent ona eMTB than a regular MTB at the same price

[@ianewers9841]

Most informative and absolutely minimal background sounds. Great!!!!. Many thanks.

[@DJaquithFL]

Hub and Torque sensor FTW. Even for center of gravity, the rearward motor and the forward battery. Also a Hub drive doesn't destroy your chain. You can have dual drive with a Hub.

[@JonathanVaucher]

How about the Bafang BBSHD, BBS02, BBS01 and Bafang Ultra and Ultra Max, all these mid-drive are at least twice the power and one sixth of the price of a Bosch

[@jamesraftos3586]

Brilliant presentation, thank you. Kind regards James

Bosch cx on my cube. All good and no complaints. Tried the yamaha motor and that's good as well.

[@askdad]

Would you have any idea why would rear motor make noise when with load and speed would drop to 13km vs 39 km without load? I checked inside and did not see any physical damage . Do you have any video on how to fix it?

[@marksmith8663]

good info of all motors, its the way the power tapes off or cuts off on hitting the 25k limit that makes a big different

I own 2 Ebike Mid Drive System. Bafang Ultra M620 1,000 watts. 2nd Bofeili system with 250 watts. Bafang motor should be a common sight in US and Europe and you might want to look into it and review the system.

[@FWCaptain-kv6sm]

Bafang is eBay stuff..No dealers no support.

[@vectraB97]

Cannondale2019 maybe in USA. Almost every ebike dealer in Scandinavia sells bikes with bafang and other systems. Especially since bafang max drive was released.

[@JonathanVaucher]

Dealear is USA are afraid of progress. The also only look to sell products on which they cand make ridiculously high profit markups. Like the 7000$ 250W Bosch... Why would they ever want to sell you a cheap 1000$ overpowered 1500W Bafang BBSHD ?👌😁 When they can make 4000$ profit selling you the bosch unit that no one except bosch technician know how to service and repair

[@quantum12b]

Great overview reviews Steve ;0) One thing that wasn't mentioned was the IP rating on each motor and battery system?! It's a bit like the elephant in the room on ebike tech stats! How waterproof is each system? What are your views on this at EMBN? The only published IP rating I have found after extensive research is Bosch at IP 54, which means its only splash proof! And Brose a IP 56 for the motor and IP 67 for the battery, which makes that system virtually waterproof. I feel like its a hot topic, especially when we are riding our beloved ebikes in wet and muddy conditions! Many thanks for considering this a video topic ;0)

[@jumbleross]

Terry Brightwater totally agree with you mate, I work in the power electronics industry and supply power semiconductors to companies who design and manufacture inverters for motors and was looking for one for my wife and was shocked to find non of them are IP67, the Spesh one using the Brose System is the best out there. It is certainly something they need to address for mountain biking. I guess the issue the companies have is if you totally seal the unit then in hot countries the thermal trip will kick in when the motor gets too hot, so perhaps some more work needs to be done on managing the thermals. I do wonder how much the manufacturer’s are going to behave to units under warranty with water ingress, totally understand that bike parts can fail due to wear and tear but these units are not cheap to replace.

[@quantum12b]

jumbleross thanks for a great reply :0) Not being in the power electronics industry, I didn't know about the thermal trip when the motor gets too hot, especially if it's fully sealed! Maybe they need to make motors for hot countries and motors for cold wet countries? Certainly riders in hot climates have not had the problems with there ebike motors, as the riders have in cold wet climates :( I live in Wales UK, so my next system will be a Brose ;0)

[@stevejones7956]

HI Terry, yes i agree, thanks for pointing out, it was something i missed

[@PhilWhitten]

[@k.zekeswaringen2122]

Very good explanation about e-bikes. Thanks for sharing !!

[@EfficientMan]

What happens with drag when run out of battery, does the system disengage in these three brands only?

[@linnemeyerhere]

Do you think there is chance a mfg'r will come out with a re-gen feature that quickly switches off for gravity downhill work that changes to a climb or power need? Could that maybe give 10-15% back on some rides.....or more? The Prius of mountain bikes.....haha.

[@denisemitchell4531]

Very cool show once again, very informative and great to learn more about all the options, you didn't show the Giant cockpit and display it has a very simple power control switch similar to the Evo and a great central disply that the back light can be dimmed or swiched off for night riding. The Giant has the walk assist function, know the specialised now has walk assist, do all the brand's now have that feature ? Thank again for a great program Tich Mitchell Cape Town South Africa

[@stevejones7956]

Hi Denise, yes most have walk assist, although id avoid going to places that require you to push your ebike! Haha

[@shanrafnezden7958]

Very useful! Thanks...

[@Davidm-M0TPT]

Love the Bosch it also has shift detect that helps with gear changing ;)

[@C_R_O_M________]

Is it true that mid-drives eat up chains like cheerios? How often one should expect to change them (chains)?

[@karelkramer5488]

I change mine every 500 miles. It will last longer, but the cassette will last better, and I don't want to risk breaking it.

[@metalmicky]

[@bingbing7606]

I currently have a 2x11 drive train on my mountain bike.No E!... yet. I am thinking about getting an Ebike but I have some question of whether it will be worth it for me, and here's why. I tow my 12 foot 23 kilo/50 lbs Town and Country Dirigo kayak behind my Mountain Bike (with gear - up to 65 lbs/29 kilos. I am able to do long hill climbs with it and go long distances also. I can climb hills with my granny gears barely but that is with 2x11. Are there any ebikes that can be converted or modified to a 2x10/11/12 to still allow my to ride up hills on distance trails with this extra weight. Will a emtb allow and ebike to pull this weight with using all the power? Or do I stick to my regular mountain bike and just keep converting it to a 2x11? It would be a lot of money to find out that an ebike just won't be able to do it. The other bike I was looking at was the Riese & Müller Delite Mountain which is a distance bike but I still like unhooking the kayak and still doing my mountain biking which I can't do with the Delite Mountain bike.

[@IthacaDon]

Do any of the systems allow you to recharge the battery when pedaling down hill?

[@Alexander.K250]

Actualy not, a feature like this is just available for backwheelmotors.

[@JonathanVaucher]

Regen breaking's purpose has NEver been to recharge your bike, but rather to cut down on break pads / brake disks wear down. In one ride you typically don't recharge you battery 2-10% with regen. No-one will be fool enough to pedal 100miles with e motor drag just to get 20miles range back into the battery. Ebike just don't have much inertia like a Tesla does...

[@nycewheels]

Specialized uses the Brose motor in case anyone wasn't sure.

[@DerekLHays]

@NYCeWheels are you saying Specialized re-brands the Brose motor as their own? The Specialized Levo website clearly states that the motor is branded as Specialized, not Brose. Please clarify.

[@nycewheels]

We don't sell Specialized so I don't know what they advertise, but it's certainly a Brose motor between those cranks. It's tuned to Specialized's liking but is made by Brose and uses the same belt drive technology. They might brand it as their own since they are the only ones with an app that syncs with the system the way theirs does, that's the only thing I could think of. Sounds very Specialized to brand things as their own that aren't truly theirs ;)

[@vogelimarc8795]

Specialized use Brose witch they tuned with theyer own Software It s true and no Secret. Its the Same thing with theyr Dh Tires wich are Copys of Maxxis Tires

[@Huxler10]

which bike do you have

[@chuckbechara7472]

Gent great job on your presentation, and appreciate your hard work in presenting the specs, that frankly dealers won’t give you. I must say the facts about the Rocky motor are not quite accurate. The torque is more like 127 Nm. Also has the highest production of max watts. This motor is by far the strongest on the market. I understand you have sponsors and they make/use great motors, I own a specialized and love it, but if your are presenting EMTB as unbiased reviewers, I expect accurate reporting. I really depend on this network for info that I will base my buying decision in conjunction to my seat of the pants ride. Thank you. And keep up the good work. E bikes will be the future of bicycling....

I started ebiking in early days as had epilepsy so needed transport, trouble i found using befang they had a poor metal drive stem on motor in side fitted to coil and non changeable, i broke mine 3 times just on normal road use and trying hard not to use power until i have pedaled up first. Mine has throttle and pedal so i disconnected pedal assist and so far its ok. What i am waiting for is a better bike and more reliable motors but from what i have seen there isn't one yet. Lots of new motors 2018 so need some test results

[@mattchay84]

Great video, very informative 👍

[@Roger101Watson]

I like the Bosch best, smooth transition between the modes and tails off nicely when you hit the max. Shimano is my second choice a little more abrupt than Bosch, batteries are a little to bulky for my liking. Never tried Yamaha or Rocky Mountain so no idea. To many people I know have had countless issues with Brose/Specialized motors so that wouldn't be an option for me.

[@Strange-Viking]

Segway mtb's and urbans use the bosch performance line too. If you chip it they easily support 45km/h and can go up to 65km/h but beyond 45 you get gearing issues.

[@robbchastain3036]

Thanks, Steve, this is an excellent overview. And I like your line about motors and water not being 'good mates.' And for myself, my first toes in the water with ebikes will most likely be an add-on motor for two reasons--cost and I want to get my hands on this tech.

[@paulbissonchery8706]

Do these motors include the Bianchi motor on the rebal ebike do u know, and as a comparison how do they differ as they have 1 more gear than the bosh or Shimano systems.

[@PrzemyslawSliwinski]

Wow! Wow!! Wow!!! Now we have that officially stated: "a 1.2kg weight difference isn't so important"! I've knew it! ThnX! ;)

[@embn]

Definitely, with e bikes, it's more about motor placement, and, of course, also how you use the power you have!

[@Mr.ZiggedWhenHeShouldaZagged]

On an eBike it’s a small difference, power to weight ratio. That would be significant on a regular mtn bike

[@tamasvarga67]

Not if Haibike/Bosch is a sponsor of the channel... when the aging Performance CX will be updated with a lighter version then it will be an advantage you can be sure. :) I think 1,2kg (and the smaller size) is significant even on ebikes hence the Shimano E8000 became very popular just in a year.

[@elyhim]

You know, some of the fastest riders in my areas are looking at my e-bike and deciding on a brand. They like their work out but they also see that the race for competition has taken something they loved away. On the e-mtb it is returned - no more strava worry or weight worry, it's back to explore, sessions and flow.

[@tamasvarga67]

I have both ebike and regular bikes. At the moment I wouldn't want my ebike to be my only bike. Regarding the weight I don't care too much about it my enduro and trail bikes are close to 14kg. Ebikes are generally heavy with their 22-24kg and if I can be closer to 22 by going with a lighter, smaller, more current system and closer geometry to a regular bike then why not?

[@JonathanVaucher]

A poorly designed non robust overpiced mid drive unit. Get abafang BBSHD instead

[@briandwyer7232]

I think you'll find that the Specialized is just a rebranded Brose motor. Brose unlike Bosch and Yamaha allow for bike companies to choose their own batteries and control systems. I believe Focus are the only company that Shimano allow use non Shimano batteries.

[@soundwave6769]

yes you are right same as Yamaha have there own motor for there bikes like giant so they can have there own display and batts and software that they can use with a brand motor.

[@emtbtrailrider539]

Yamaha has been configured by Giant to make the PWX motor even more stronger & powerful

[@markotrieste]

Exactly, there was little point in analyzing brose and specialized separately.

[@zyghom]

Fantastic video. Thx

[@joshgracin59]

Are resistance band weights accurate?

[@peterkinsella5888]

A couple of points on the Bosch system. I tend to ride quite economically and frequently select the "Off" position when riding on flat or gently undulating trails. When I do this, I backpedal for about half a revolution and there is an audible click as the motor decouples. I have one bike with the Nyon system. It's unreliable. The first one stopped working and was replaced by the dealer. The second one lasted about 6 months then failed and was sent off to Bosch for repair. It came back several weeks later and now seems to be behaving itself . The GPS mapping system is inadequate in capacity. I can have the whole of Europe on my Garmin but only part of France. Seems to be a bit of poor design specification there.

[@jacktonucci]

Peter Kinsella are you serious about Bosch decoupling? Half a back stroke and no resistance pedaling without motor on? That would be amazing!

[@peterkinsella5888]

It seems to work quite effectively. After the click, it seems to pedal more freely.

[@ianrav]

Loving this whole EMBN channel! Quick question - have a Merida eOne sixty 800 (great bike with a great geometry running the STEPS motor) - however, I also have a saloon (hybrid) which cant take a tow bar and wont accomodate the bike in the (rather small) boot.

[@alvinhill4602]

More information on the Vee go E bikes and green bikes. Thanks

[@Metal-Possum]

Specialized motors are made by Brose, they just get repackaged (software, apps, etc.), and Specialized tend to steer the focus away from the motor's origins. I know you're never going to review Bafang motors on here because they've not been adopted by mainstream manufacturers, but there's a lot of e-bike only brands that are working with Bafang. The biggest benefit there is the power settings and software can be tailored for each country (your shirt does say "Global", so these things need to be factored in), and each manufacturer can choose their own batteries, displays, software, etc. as they wish, as long as they match up. This makes the differences between each bike considerably greater than just a few minor variations in geometry and components. It's also cheaper, which will help to open up e-bikes for everyone, not just the wealthy or fortunate.

[@robertjackson272]

I love the BBSHD with a 58v battery. More power and torque then any of these restricted motors!

[@standupmoto]

Hi thanks for an informative video , but can I throw in a couple of points- you tend to lean towards mid mount motors but may I just add with my mid mount I found it very easy to break chains on rocky hill climbs under full combined power & as I live in a sandy dry area maintenance of the chain & sprockets was a continual pain however with the hub mount I have increased my power considerably & virtually no maintenance. The enclosed mid mount gearbox does run a chain but it’s much larger & no derailer , nothing hanging down to get wiped off in rocky terrain. Just a thought.

[@johncarlola]

what about Bafang?

[@arturpasnik]

Exactly how he can dont include it, I am disappointed.

[@DaveWarnock]

Are there any standards for how motors fit to the frame or does each manufacturer have their own? Are the cranks standard or again do you have to get oem replacements?

[@Julio-wd4xl]

Thanks for the video Steve, very informative. Sorry Steve off topic question, Can the rear shock of your Kenevo Specialized fit the Levo Specialized?

[@GoneRidingPartsCom]

LEVO De-restriction question: Aside from increased heat, does it hurt the motor to run at higher RPM's if the LEVO has been de-restricted ? especially if it was only used on occasion & not like a road bike. I am tempted to de-restrict the LEVO, but I don't want to break it.

[@ebikesmile2743]

Another great video guys! You said some motors are hermetically sealed. Which ones? Would be great to hear about the Ingress Protection (IP) rating of the electronic components including motors and batteries as this is the way riders can accurately compare the brands. Cheers

This issue was raised recently in the "eBike Smile eMTB Community" fb group recently with lots of links to and saved in the Files tab for future reference as so many riders are now asking about it. A company from NZ will be releasing a fully waterproof IP68 motor and battery later this year! Exciting times.

[@miguelatambucho748]

Great review. I am looking forward the battery mike range.

[@michaeltowler2632]

The Powerplay control is good, you're showing the very old type, the new type is so much better, even more smaller and streamlined than the Specialized, It's so easy to change the power modes and the colour of the lights tell you what level with just a glance if not sure and the Battery level as well. Also I've altered the levels via the app, ecco 60% Trail 75% ludicrous left at 100% and ride in ecco most of the time, no need to conserve power here and as the Motor when off reverts to my setting of ecco I don't even have to change it up when restarting the Bike for a ride. One of the biggest plusses is the instant torque if misjudged and your stalling on a tricky Rock and have to Pedal and would strike your Pedal for sure, with the Rocky you can just jiggle the Pedals an inch or two and power over. No I don't work for Rocky :))) I'm an OAP.

[@Mindycogswell]

Can someone who rides an ebike regularly give me a bit of advice please? I'm a big bloke, 6 feet 2, 16 stones and I live in an area that's all valleys and steep hills. Would a UK road legal ebike get me up these hills with the minimum amount of leg work or would they struggle?

[@stuartcareless9550]

What's the life span of the motor and batteries?

[@Mr.ZiggedWhenHeShouldaZagged]

The speed limit, is that based on motor speed with calculated gearing? Can you put bigger chain rings on and sneak past that?

[@embn]

Good question - the pedal assist speed limit is set and is often a legal limit, too, so there's no getting around it with chainrings, and, if you do, you might be breaking your local laws.

[@Mr.ZiggedWhenHeShouldaZagged]

Legal systems notwithstanding, is it possible? I live in Canada where there are no legal limitations, however, we end up with out of market limits on some bikes.

[@elyhim]

From my experience with a couple - you need to void the warranty by hacking the motors. Changing the chainring won't do it.

This speed restriction bs takes all the fun out of it. I like going fast. That's why I still use an older controller system. Until I figure out how to flash firmware on the new ones.

the worst part is, you can easily pedal above 45kph even on a shitty 200€ hardtail, so the 25kph limit makes no sense. At least make it 30-35 but with a "intentional" drop off in power assist. So we dont just suddenly get to a "speed cliff" where we get drag

unless i am missing some other factor power modes should be expressed as a % (the highest being 100%) of total power out put for a certain motor (eg 250w motor, eco 25% 62.5w ,standard 50% 125w ,turbo 100% 250w) this way it is easier to compare the power vs multiple modes and motors(the way each motor delivers its power is another issue that has more to do with feel and perception). cleaning compressors use oil as a lubricant so spraying any electrical connection will inadvertently put oil on the connectors try using computer spray cleaner and electrical contact cleaners but beware most of these are acidic. cheers and ill keep bing watching.......E-curious ;)

Great video, only minor mistake IMHO is that you failed to mention the correlation between Brose and Specialized. Questions/suggestions from my side for further topics: -add Continental and Panasonic systems to the comparison -make some test about input vs output power using strain-gauge on pedals or cranks. also efficiency and range test in controlled environment. -what's the point of having 80 or 90Nm of torque if, with 250W, this value must decrease above 30RPM of cadence? OTOH, what is the peak power of these systems? (250W being the continuous rated power. I have evidence that you can easily get 400W for short periods) -What is the point of having 300% assistance if an average cyclist can crank out 150W on it's own? If the limit is 250W, that leads to the conclusion that anything beyond 180% assistance is just stealing your sensitivity, without adding actual power, right?

Like your thinking Markotrieste, i'll certainly be following up on some of your suggestions! Please keep in touch

Hello, is it possible to change my 250W motor on a Zipper Z4?

[@brucekendall52]

Thanks again.

[@DaveE128]

How are the Brose motors at high cadence?
