Electric bike V3

[@tilago]

I read a few comments confused about the power and pricing, and since I know a bit about this kinda stuff I thought id try to leave some info. Yeah, 700 euro is a lot to spend on parts for an e-bike. But compared to a kit you can find online for a similar power/torque/speed spec’d bike, you’d be looking at closer to 1000 euro. A completed bike with this much power? More more 1800 euro if not more. I built my electric bike using a 3kw hub motor, a 12.5 ah battery, and a 40 amp 52v controller. That alone almost cost me $1200 US. When you consider the brakes I bought, with the bike frame, and the lights, and everything else, I’m in something like $1400. My bike has seen 40mph in ideal conditions, and done 650m altitude climbs without a sweat, but I suspect the bike in the video is capable of the same with some minor tweaks to the gear ratios. For what this bike is, with the care that’s been put into the design and reliability, it’s incredibly cheap.

[@TomStantonEngineering]

Excellent explanation! It is very easy to focus on the price and forget that performance comes at a cost. You justified the cost very well. Thanks!!

[@xavirei97]

Raycool scooter 1900w cost 1200 euro and more speed 60 70 km/h

[@Немања-х1щ]

Tiago can you help me Tiago, I am looking for an electro motor with a regulation like for mounatain driving, how i habe to calculate that whole thing when I want to say I want do drive cobstant 20km/h towards the mountain. is 500watt enough? an which battery to this? many thanks

[@bamikroket]

How much does it cost to get it certified though? I don't know about other countries, but over here if it goes over 25 km/h it's a moped and needs to be "road legal".

[@virtualfpv3568]

Awesome design!! I love how in the end the power from the motor is transferred to the wheel via zip ties.

[@ghicione]

Great build! I am sure it has been said before but here is once again from me. You got this all free space behind the seat tube and the tyre. That is a great place to mount the motor so that somehow is in line with the frame. That only the pulley is sticking out on one side and the cooling fan on the other.

[@mabbs2757]

Gr8 job for staying with it Tom

[@Coltrabagar]

Yes, the quietness is one of the first things I noticed. Good job. Props.

[@mystscot9814]

Much respect to you Tom for deciding to build your own e bike from scratch rather than buying the more expensive branded e bikes.

[@glennboland4673]

Have u considered selling the hard wear, mounts pulleys and belt as a kit. As I would love to build this. But I have no 3d printer.

[@Patek007]

Glenn Boland what he did right there took him hooouuurrrsss

[@M3iscool]

So?

[@Patek007]

So that means he would not want to make loads of these mounts I have done it myself and it is really hard and time consuming stuff he made that mount for exactly sk3 motors so it would probably not fit on different motors

[@M3iscool]

Oh, okay, yeah. That's true. I guess he'd have to find someone to help him manufacture them. I dunno.

[@SaitoGray]

You can order 3D printed thing on Internet. It's a bit expensive, but it's cheaper than a 3D printer.

[@richardbridgstock4636]

Hi Tom, Such a smart kiddie! Maybe a simple(ish) mod to relieve the squeeze on the motors by the small belt would be to incorporate a short shaft protruding from the back of each short belt pulley. A straight bar with a bearing for each shaft would hold the motors spaced correctly and relieve the tension.

[@aloharay]

It has been really interesting to watch your project develop from version 1, into V2, and now V3 (and all the iterations in between you described). Keep developing!!

[@THEfromkentucky]

Dude seriously, get a wider handlebar and maybe a shorter stem. I promise it will dramatically improve the stability of the bike. You'll feel much more comfortable on it.

[@locke_ytb]

Thank you, you even helped me out. Even though I have no bike.

[@locke_ytb]

Tom, I will definitely come back to this video (maybe your latest version of your eBike) when I get my own bike.

[@LuisMCastroL]

Hi Tom, can you share a list of parts that you used? Maybe a diagram? Thanks, I want to build one so bad. Excellent video!

[@Rockstarbird21]

Even i

[@monsieurbacteria2314]

Hey guys, I'm currently in the process of making my own 3kw bike and I figured out these are probably the best parts rn: kunray 3kw 72v motor kit (includes the controller and a throttle as well as the motor) 275$ 72v 20ah battery (this is just a pre-made battery pack that works with the controller) around 275$ as well my best bet is amazon for these

[@monsieurbacteria2314]

all you really have to do is make a mount for the battery and motor, as well as changing the sprocket on motor to fit bike chain.

[@t.sb_0570]

i have a 2011 sparta ion rxs + ebike and it works really well but your electric bike v3 was like my child dream, i can remember me putting my dad's powerdrill on my bicycle's rear tire to make it go fast but i think the fastest i ever went was like 15 km/h

[@championdnb]

Your effort, the details you share and the videos in general are so on point. If you need any music for your videos (probably Drum & Bass) let me know :) Big fan over here!

[@XJohuX]

Champion i would like music in his videos :)

[@alexyegon2381]

no music please, that's why we are here

[@MCsCreations]

Fantastic work, man! That bike is awesome!

[@MCsCreations]

I liked a lot the way you made the batteries. Much easier to charge than a full pack.

[@Jabberwoky]

A much safer and neater iteration of an electric bike than the last version. Can't say well done as still illegal but some excellent engineering problem solving. As a motorcyclist I would always advocate using gloves, Tarmac at 30 mph will remove flesh and they keep your hands warm!

[@tonysshadow]

As soon as you put hammer down ....I was immediately reminded of the sound from the old 1960 movie The Time Machine (George Pal version).

[@mahachooev894]

Works great just as it should

[@jlucasound]

@ 20:30 I do remember the rear brake clearance issue. You cleaned that up right well!

[@Asger2700]

I would love to see you try different setups either with batteries or the vesc settings, to try out different power (Watt) outputs. It would be awesome to see some stats/graphs regarding the speed/acceleration as a function of the power output :) Great job on the build and the quality of your videos recently!

[@Hoggdoc1946]

This new design seems to be much more rugged. I will be interested in seeing how it hold up over time.

[@ziggymike1]

Splendid work, both your bike and your videos. Pleasure to watch.

[@samslo1808]

I really like what you have created... I hope you are able to get it packaged for consumer... You might have a small fortune in the making

[@sundancesquid]

You done a nice job of that Tom, top marks fella.

[@cieszynn]

Like what you did there, for the version 4 I recommend you take a look at ebike parts (controller cost 10$)

[@wtmerit6129]

Great job Tom. 3D printing, latest technology motors and batteries, etc.. Great info. Trying to build a light weight small as possible sit down foldable scooter for daily alternate local transportation. Thanks for sharing. Good for saving the enviorment and helping this new industry get out there. Hope you get knighted someday. Will donate and am subscribed.

[@plankins4702]

i cant believe this, a week before i saw your other videos and wanted to build a bike, now this! Thanks!

[@GareebScientist]

Wish this cycle was a geared one. Then you could connect the drive train to the front gear, and enjoy a bike like feel

[@darkkevind]

Love it! Great work Tom, much better than your other iterations. Glad Frank hooked you up with a Vesc6 ;)

[@leahparsuidualc666]

This is madness.

[@prizedcoffeecup]

The short footage of them letting you try an electric longboard is oddly satisfying anyways...I find the gear reduction on that motor way more satisfying than I should.

[@vusvis]

I discovered your channel just today and I must say it's awesome! You're doing very nice projects, they make me even a bit jealous...

[@tehnikprimitif3833]

I really like, very difficult to change the bike in such a way ,, fast and stable

[@dtbjason]

Are the plans going to be uploaded to thingiverse like the V1? I just got the green light to start this project from the big sponsors (parents) The motor sensor is so trick! :) To me the kits' selling points are how it could mount to so many bikes, very clean minimal appearance, very practical in an urban commute. My wife uses a super-China e-moped, long range (40mi) not horrible speed but small wheels (rough) and HEAVY! What you have here is exactly the kind of power/weight ratio a 125lb guy like me is looking for, just enough to be able to get myself hurt on - perfect fun ;)

[@BlazeFox89]

One thing you need to be careful about when riding an electric bike is that birds won't be expecting you to come up on them so fast with so little noise. It's fun to see them fly along with you a few feet away from your face, but I've almost hit a few too.

[@aserta]

Make the pulley as large as the wheel allows (that's how old bikes were made), reverse the motor over the wheel and make a scoop (that's damage protection, and you can hook yourself much better by using the mounts meant for fenders for example), Mount the pulley on the rim itself using holes drilled on the bottom and spaced with L brackets or simply bent thread. That's a lot more force you can apply than though the main wheel shaft + more distribution if you put say...15 such mount points. And mount the batteries under the frame with an aluminium bash plate. Frankly, in a bike like this, go as low center as you can.

[@aserta]

Also, try making an assisted pedal design as well, that should give a lot of thinking kicks. Not as easy as it might sound, plus, less dependency on batteries.

[@thepandaman]

I'm sure that's a private road you're testing it on ;) Really hope the laws in the UK get updated soon to help accommodate something like this! The current restrictions are rubbish :(

[@raindogred]

Brilliant engineering and great challenge..been a lot of fun watching ur progress. When you take those runs and go flat strap, I get worried :) I don't see the point in going faster..if you want that - get a cheaper petrol scooter..second hand could get something that run around for 2 weeks on a full tank, for cheaper than you have outlaid for your project, and go a lot quicker, and be a lot safer. For the environment..I don't know if charging batteries from the grid/coal every night, is it any better than buying a few litres of petrol every 2nd week..solar is different matter? What you should focus on is going farther, at a safer speed

[@TheVelomobileChannel]

If you mount that to a recumbent bike or velomobile you get much more speed or range because of improved aerodynamics.

[@andrew1717xx]

Saukki **Raises Left eyebrow** :) But, you lose the beautifully camouflaged illegal bike, that hides in plain sight. ;)

[@DKTAz00]

I built one some years ago, outrunner with a nylon cover just mashed on the rear wheel. Did 50mph that, with a 12s. I have a video with an 8s on my "channel"

[@JettHansley]

DKTAz00 mph and kph are 2 different things

[@DKTAz00]

Not sure what you mean. I'm natively kph, so 80 kph :p it was a head turner. Untill the esc burst into flames going uphill and nearly grilled my behind.

[@JettHansley]

DKTAz00 u said 50mph on ur comment but it says 50 kph on ur vid

[@DKTAz00]

Right Right, thats the very first run with just 8s cells, lower voltage.

[@parjacpar3077]

Thanks for sharing another great update to your Ebike down side is have you checked out the laws that cover it ? . . . .You will find that you need a motorbike licence , tax , insurance and a log box for your ebike all because there is no pedal assist.

[@CrzyZeke]

This is an awesome project, just became a patreon supporter. I am wondering why you don't have an octoprint setup yet?

[@TomHaslett]

I just recognised that corner at 4.26. You are not far from me! You cycled past my friends house, that was an odd moment! Looking to build an ebike myself and toyed with one of the ebay (Voilamart?) ewheels or doing what you have done with RC gear. I'm leaning more towards the ewheel after hearing about some of the issues you have had. Your one sure looks like fun though! I'm liking your 4s in series arrangement. It makes them easier to charge and use the packs for other projects :-) I might steal that.

[@alexsansative7119]

Very cool looks your bike Tom! Keep doing it!

[@SapioiT]

More, please!

[@kennethbellmyer9241]

Duel motor mid drive ...bro bro! ,I want that kit!!! Woo hoo!

[@Jasonoid]

Here I am watching thinking he is riding on a bike trail! haha, those are some skinny auto roads!

[@ashpunting]

gosh your bike is crazy fast sounds like a jet i wish my e bike flew like that. one love bro. crazy

[@AustinChopra]

make sure to charge the batteries to 4.1v per cell to prevent damage to the battery and make them last longer

[@sabership]

Nice! Can you make an Epicyclic Geared IVT for Electric bike V4? That would be one hell of a bike to see!

[@W4WEnglish]

Amazing job, welldone! Have you thought about adding "guards" to the rim pulley, so the belt doesn't slip off? Do you think this configuration could work on the front wheel?

[@Zallestial]

So wish you tried it with a recumbent bike instead. You could easily half your air resistance and reach much higher speeds with a more aerodynamic model. Much greater break efficiency as well with the lower center of gravity. :)

[@itsmaxlim]

Thank you fro great video. Is it possible to have some kind of clutch to avoid motor resistance while riding it as regular bike? What do you think about it ?

[@TomStantonEngineering]

It is probably possible, but adds complexity and removes the regenerative braking capabilities. To be honest, I only ever ride this bike with the motor running anyway, otherwise I'd use another bike. Applying a small amount of power to the motor whilst pedalling makes it ride like a regular bike

[@eddyjawed4871]

You're just simply awesome man. Love to meet you in real life and learn something

[@CaseyFinSF]

You live in beautiful countryside! *When do you start working on the Tom Stanton Hover Bike?*

[@coolkeel]

awesome ebike built! everything looks so clean and perfect! its only missing a cycle analyst to get some data

[@TomStantonEngineering]

I've ordered a bluetooth module for the VESC which can display all sorts of data onto my phone! Thanks!

[@phanindraravi207]

The bike is really awesome!👍

[@theowlsgo]

Hey Tom, if you get a chance would you consider posting screenshots of your VESC settings in BLDC tools? I am running a similar setup on the bench and having some trouble with my motor.

[@SirBeauJangles]

Impressive effort. However... with all that MPH available don't you think that uprating to at least a single disc up front might extend your life expectancy a bit? If possible I'd be inclined to try a twin hydraulic set up, one on each side of the fork. (I'm a pensioner who rode big fast m/cycles for years - remember, doesn't matter if you can't go. But it sure does matter if you can't stop!)

[@thepvporg]

And also read the Highway Code and read the legislation about the max power and top speed allowable before the cycle is deemed dangerous. Don't forget that a cyclist killed a pedestrian doing about 24mph... If you're doing 30 or more on a cycle and can not stop and you hit someone or something, you can end up killing someone, yourself or both of you... (off the .gov.uk site) ==================================================== Its electric motor: must have a maximum power output of 250 watts should not be able to propel the bike when it’s travelling more than 15.5mph ==================================================== and goes on to say... ==================================================== Any electric bike that doesn’t meet the EAPC rules is classed as a motorcycle or moped and needs to be registered and taxed. You’ll need a driving licence to ride one and you must wear a crash helmet. ==================================================== So there you have it folks. You can build your e-bikes all day long as long as you don't go over the limits...

[@valderja]

Nice work and very enjoyable video to watch. I love projects like this. Are you still flying heli's? I've got bitten by the bug again!

[@TomStantonEngineering]

I've still got my Trex 700E sitting on my shelf haha! but haven't flown it in years. Thanks!

[@Esona]

Curious, Tom, how do you go about your research for what motor to buy? I've been entertaining the idea of building a remote controlled snow plow (Canadian, eh?), but I'm not sure the type of motors to be looking at/for. I'd appreciate your input on things to look for :)

[@andrew1717xx]

Esona You know I'd either help you work on that. (If you live in the Maratimes), or I'd build one myself.

[@nathankennedy8704]

Iron Mangos, those would be brushed motors, which aren’t nearly as efficient, correct?

[@TomStantonEngineering]

I chose a motor based on lots of different things. Surprisingly speed is not an initial factor for me (this will probably change with larger vehicles), because gear ratios can always be adjusted. Usually the motor isn't the most expensive part, so I will tend to see what battery and speed controller will fit my budget. Then I'll work out a battery depending on what the maximum voltage and amp rating the speed controller can handle (60V and 80A in this case). Then I'll work out whats the largest gear ratio I can fit on such a setup (about 1:15 in this case). The 'hobby grade' motor used on this bike has a kv rating, which means the RPM it can reach per volt. So this motor is 160kv, therefore with my 50v battery, it can spin at a maximum 8000RPM. then using the diameter of the wheel etc I estimated about 36mph, which is plenty of speed. This might be completely different for larger motors as I have no knowledge of that field. So it's a bit of a juggle of components to get the right setup. Thanks

[@7alken]

Hi, very COOL (ehhh :-)) project! Nice you are back with the rear brakes and even KERS :-) ...And that you think about heat more too - how hot is the VESC? Wouldn't be good to have some heatsink on it too? Isnt some serious voltage drop on the cables also?

[@zaraaaa420]

with rim brakes this whole time is crazy

[@saldi3543]

Tom this version is awesome, Just for the batteries, I've used the Samsung 18650 25R for my electric motorcycle project those are pretty cool batteries, just a suggestion

[@guzer3933]

Can you recommend another ESC for a bike/motorcycle/cart in the 6-10KW range? So far I still could´nt find any equal to the one you do use here. There are amazing things that could be done with that compilation! Awesome work! But I really would use mudguards :D

[@10acebikesjodybennettii19]

Tom why wouldn't you lengthen the belt mount the motor above the rear triangle with the pulley hanging out in the side to propel the bike you would have to change the direction the motor spins but would clean up the look on the rear and take weight off the single side??!

[@farktard2740]

There's a tight corner coming up, I won't catch those birds!

[@gkdresden]

Instead of using such a large pulley for the bicycle wheel you can also use a multi pole axial flux motor for direct drive, printed by yourself. :D

[@Lilpiip123]

U should add a display on ur bike that will show how much power ur applying, the battery level, how much many miles u have ridden, hiw many miles can the battery last and so on... That would be awesome!

[@pierremonico5002]

Very nice work! Do you think it is possible to mount the brake on the inside of the frame? Kind of inside the "triangle". Could save space and allow for mounting the motor on top of the wheel, where the brake now sits.

[@RinksRides]

A sm bank of supercaps will improve regen charging and instant torque on throttle hits. then just need current limiting to/from the battery to protect the life of the battery from over current situations.

[@parapobabam]

now integrate a super capacitor bank for a turbo boost.

[@stonebayrocker]

Alright. Have seen all of you e bike videos straight on! Very impressive and cool to see you engagement and passion going through so many versions and so much money on this project! 👍🏻 I have wanted to build a ebike for a long time now! Do you find it annoying with the motor sticking out on the side?

[@theeoddments960]

Damn. I put a lot of time and effort into a motorized bike that goes 43 mph and you’re here going mid to high 30’s with a bike that you’ve slapped a couple batteries and a motor on. Damn.

[@Buffetology]

Hi Tom. I also have a Vesc. Can you do a video on how you added the second regenerative throttle to the Vesc?Thanks for all the great content.

[@dominikdziadziuszko8771]

nice job man you inspire me to do those kinds of projects!

[@TomStantonEngineering]

Excellent! Glad to hear! Thanks

[@PlantiPal]

For other ride test like this, it would be great to have an on-screen speed readout overlay.

[@koz]

Really fantastic stuff. Incredibly impressed by your engineering (in other videos too). Amazing to see the 3d-printed cog on the rear wheel. In PLA too. I'd be quite concerned about what bits might fly in which direction during a catastrophic failure. Either from that cog failing or the motor or belt coming loose at speed. Make sure you tie up your shoelaces! ;) Those lanes are just like the ones I grew up cycling around in Somerset. Keep up the excellent work. From what I've seen so far, expect offers from the likes of Elon Musk soon. Seriously.

[@raydenkundera857]

Hi Tom, this kind of motor at which voltage works? I have an idea to spin the wind turbine when is not wind outside, hope it will work. But l need to know on which voltage works because l need to be 12 V. Thanks for your time and work, keep going man and why not maybe you build the same bike but for money this time ha ha. All the best mate

[@Sidetops11]

Wow it's really fast! A bit faster than my 1000w Stealth too, which will do around 30-32mph on a flat.

[@elhigh]

Wouldn't it make for a cleaner install to put the motor inside the top of the rear triangle? Flip the motor 180, center its length on the bike's centerline . Build your mount to clamp around the seat tube, extend stabilizers to the seat stays if necessary.

[@TomStantonEngineering]

I considered this when building this V3, however I decided not to for simplicity. Moving the motor upwards meants running the belt up and over the rear brake. This would make the belt very long and therefore increase the possibility of it stretching under load and skipping. Also it would be more difficult to slide the motor for tensioning the belt. I'm sure it's possible, but I prefer the simplicity of this setup. Thanks

[@FinnishSnowmobiler]

Tom, that's one hell of an electric bike! Really solid build! If you only did a burnout video... (dirt, mud or ice)

[@TomStantonEngineering]

Thanks!

[@beetbocks1]

Hi Tom- great build- has inspired me to build a similar project- how are you applying the Regen brake on the VESC?..do you use the VDC channel 2- because i cannot get it to work as a brake- im wanting to use it also on my E-scoot - could you take a screen shot of the BLDC tool ? thanks in advance Rich

[@TheRealMrLaserCutter]

Great setup. I am interested if you made any changes to your 3d printer settings to get the HTD 5m profile to fit. I am trying to get some dimensions on my pulley to be more accurate ie the internal bore is almost 1mm to small. I have just purchased a MK3 prusa and this is my first printer. So should I be looking to adjust my cad file to compensate or should I use some sort of compensation in my slicer? Many thanks

[@AndreaBettati]

Maybe this has already been asked, but still: is there an active project for an open source cycling on-board computer? I mean a computer to collect data/gps and build statistics for a standard bike, not electric. Of course this could be interfaced with the motor controller in case of electric bike. So, anyone aware of such a project? By the way, congrats to Tom for the great builds, this is inspiring:)

[@fizzyelectricity]

I wonder how much a lightweight aerodynamic body would improve performance and range ? I'd love to know the difference it made, that would make an interesting video !

[@Karatektus]

I am in the planning phases of my electric mountainboard.... and speedcontroller wise... the vesc 6 is just so expensive. its more than double the previous price..... and I need two! I was thinking about the Focbox which costs about half of a vesc6 (150€ vs 330€). I really am in doubt here :D

[@DavidAlsh]

Hey, love your videos. Can you give me some insight into the process you go through to select an electric motor? Perhaps a few examples of how you'd size it for the application: eg, electric bike, electric model plane, electric go-kart, electric car conversion.

[@TomStantonEngineering]

Hey David, I chose a motor based on lots of different things. Surprisingly speed is not an initial factor for me (this will probably change with a go-kart or car), because gear ratios can always be adjusted.

This might be completely different for electric cars as I have no knowledge of their motor specs. So it's a bit of a juggle of components to get the right setup. Thanks

[@tonykett]

v1 did look a lot cleaner though. if you're into looks :)

[@honda4004]

what about mounting some pick up coils near the front and rear brakes and a strip of coils down the rear frame tube like on direct drive lg washing machines and also put nitrogen in tyres and neodymium dust maybe with graphite dust pumped in would create the field force excitation just a thought

[@plodderexup]

Lovely engineering but I built a drop handled ebike that does 34mph for about £200 and it doesn't have a lump of motor sticking out the side or a conspicuous large pulley and drive belt.Take one 250w, 36v geared hub motor off a 20" and string to a 700c rim.Use a 36v/48v cheap Chinese controller (the FETS are good for 70vGet 2 off 8s lipo or equivalent and wire the 16s to the main positive and the 13s to the controller switch (door lock) via a power on switch.The unloaded wheel speed is about 600 rpm, so about 21 m/s (about 45 mph on as 700c rim.Without soldering the shunt (I.e. with a 15A limit), I get 34 mph.The motor doesn't overheat; just don't try to climb mountains.A bit of ATF can be added to the hub for cooling if you want more amps; I've run these controllers at 20-22A without issue by soldering the shunt and even if it does go bang, they cost about £10-£12 each from China.

[@ronz91]

yeah that need a video lad. cmon get on it! :)

[@Немања-х1щ]

and what if i especially want to clim mountains? do i need more watt? or what should i do then

[@RS-nl2lp]

nice build!

[@bendenoma723]

Nice video, can you explain more about the Regen breaking? How it is controlled and with the motor controller and is the Regen breaking variable or just on or off?

[@ElectricVehicleSpace]

Hi Tom, how did you wired the vesc to the throttle? Thanks.

[@AQUATICSLIVE]

Wow love how it has progressed. I can see kits; if you ever wanted to go that route team up with the skate guys.

[@taba1950]

I want to build one of these one day

[@ambonirider]

Great work, but the motor should run only when the pedals are running. In the best e-bike the power of the motor is driven by the force you put on the pedals!

[@FinnishSnowmobiler]

Paolo Amboni Incorrect... The system you are describing limits the way you can enjoy the bike...
