How To make an Electric Bicycle (Brushless Motor Crazy Torque)

To order customized PCBs for your projects:
www.nextpcb.com
In this video we are going to redo the conversion on our bicyle using a powerful brushless motor while replacing the old geared DC motor.
Earlier we have converted our bicycle using a geared DC motor, though the conversion was sucessful and we were able to get thing rolling but still the top speed and the torque provided by the DC geared motor was miserable.
So we decided to step up the game and eventually we come up with the idea of using a brushless motor from an old hoverboard and some high discharge lithium pollymer batteries to give this bike a puch of power.
The conversion was stright forward as we tried to eleminate as many unwanted parts as possible during the process and thus we were able to achieve a top end speed of nearly 40 km/hr (The bike is surely able to get double that but the speed controller we had was able to handle only six cell lipo pack) and the torque was phenominal, seriously wheelies on the go.

i had made something close to this but didnt re wire the motor, used a cheap sensored controller, and had way too low of a gearing... i had 3d printed a tpu adapter for the bottom bracket of a bmx bike to fit the shaft of the hub motor. I like your solution... the torque you have got out of that motor and gearing combination is wild! Props!!! thanks for sharing!

Lovely bro

[@prabanchakmaamitabhomankoo2102]

Really amazing even I have such practical hobby to do, hope I will do that one day. What basic reference do you recommend I mean the knowledge about motors, wiring and so on so that I can learn. Please do suggest me...👍👍👍 thanks

[@Suprem3GamerDamianWinchester]

Love this video, can you do a diy esc 400A 22s with a controller or throttle ??

[@user-gx6sg4tb9s]

Good job though! Wow, the effort you put in.

[@itwasrightthereinfrontofyou]

Climp any hill with a small boat starter motor. If you were 90 degrees with front install, it would flip the rear up so you could face plant the wall/mountain/rock. If it were rear, you would be flying up the stairs in a wheelie. Make sure to feather the brake. Take one of them diesel lithium battery starters rated at 110v 100amps with a pwm(pwm brush only much stronger than brushless..brushless made for long distant constant...not best for torq). So yeah, Stunt guy like you, use a small starter motar which could pull a car at 2,000 lbs. Infact for the ultimate short burst that will climb anything use a 300 amp pwm(max hard to find- can get 150amp pwm) and you could flip get air on those stairs and flip with perfect landing. Another thing you can do is upgrade you control box to 5,000 watt 96v and overload brushless(500 watt brushless handle it for short bursts 5-8sec under heavy incline . 750watt 8-14. 1000 watt for 19-25 1500/1800 26-36 2000 47-60 and a bit over. 3000 1-2 mins.

[@hatbpto5180]

Cool! Subscribed!

[@ffss2989]

It's an interesting design, but you got the essence of a bike, which is the pedal of the bike! If the battery gets empty somewhere for any reason, it's no longer a bike.

[@tejassoni21]

Great to see first time who made Cannes in winding to increase the torque. I believe the it will increase the current draw of the battery and cause less run time. Just let me know does it affect battery run time compare to last set up. Thank you.

[@andisuryowinarto5277]

good video,

[@ask_fornature4012]

Love it 👍🏼

[@Traderhood]

Great project. I wish there was more detail on how you altered winding of the motor.

[@MrJbrantley1]

Me too

[@ex-soldier4341]

And you need to have an old hoverboard lying around to do this,funny

great! 😀😀😀

[@user-qq9kg2dj9e]

Pedal pads are ok in position or try to turn and fell off? Or you fixed them?

[@shaadullakhanasadullahkhan6292]

Masha Allah bhai

[@eone2345]

Thanks for the info. Appreciate if you can provide the subtitle please.

[@hOZish7]

Some excellent work here but some of the decisions are a bit weird. Perhaps it makes sense if this bike project was intended more to be a video, and less about actually using it. The things I would have done differently were: Found a way to keep the pedals so that you can still pedal if you run out of battery. Used a thumb throttle instead of a servo tester. Used a VESC ESC because its current control method is so much more suitable to ebikes than the typical duty cycle control (it's a nightmare starting to turn on the electrical power if you are already moving with a duty cycle based ESC, it causes it to brake rather than accelerate). Add more heatsinking to the motor, it'll get quite hot trying to use it like a moped.

[@user-iq7fd5hf9h]

super!

[@saqibkhan-kk7ic]

Lagay rahoo...

[@GrushalanD]

Dude you're cool! 👍 The success and development of your channel.

[@methanu6659]

Can u do a conversation video dedicated to making this motors faster?

[@zakabhatti7243]

Hello DIY King, thanks for sharing. Just a quick question: can the xiao mi escooter motor also be used?

[@darexg]

yes. inside its exactly same motor

[@yogeshnaik9276]

well done video, but how much kms it goes on a full charge, my office is 30 km and I want to now if you can put this motor in hub for me Thanks Yogesh..Goa

[@Attic-Toy-Design]

Have you got the drawing on how to re-wire the hub motor? Only video/pictures are not enough for a good reference...Thanks!

[@Everestb]

Hello your new conection in the motor is triangle? No star?

[@alextrezvy6889]

04:48: Where you get the hub which allows to install the disc from both sides?

[@yakz9885]

You should get a 72v 60a kt controller and run this on 20s max. Reccomend looking on the endless sphere forums for ebike research. Great build though.

[@ahmarrana9732]

Nice

[@awadsaeed5392]

Good project.. but please give more information about the part you use like the battery and the cre ..

[@eid.taslih.daraajat]

فكرة جيدة جدا 👍👍👍✌✌✌👏👏👏

[@ruantiyoruan501]

Mantap bagus kreatif.

[@pasyensyatv9092]

nice work! what battery did you use? is it for RC cars?

[@shaham3415]

It.can be used in any hobby work

[@TheMcdrewb]

How did you put tension on the chain??? Looked like it went on real easy...meaning it would come off easy?? What am I missing??

[@yogeshnaik9276]

nice, i have suggeston, plase make a motor with paddles and cadens sensor and gear motor like those in abroad of bocsh or Yamaha you are already close

[@kailashsatokia3611]

Ajab gajab he by cycle

[@Vindix007]

Awesome. I suggest you to use a bike helmet. Greetings from Brazil.

[@DIYKingSaM]

Yes you are right, will be carefull next time

[@markpieratt]

a dope a55 way to get from a to b. and a brilliant little piece of engineering . envy it!

[@johannapoder2843]

can you do video where you explain exaxtly what you did to the motor. plsplspls :)

[@sskiinventions5820]

Well Bro How Much Torque does The Motor Gets And How Much Volts Does The Motor Needs And What ESC did you used In this Project And Whats the motor and ESC Specs here

[@samermardo431]

Hello dear. When can we get some more details on how you rewinded the coil of the motor and eliminating the hall sensors please?

[@klausbrinck2137]

No rewinding, simply from Star to Delta, gives √3-fold more speed, but equaly less torque. Would be cool, if he could switch back and forth between the 2 configs, so 2-gear e-motor...

[@IUbU]

@@klausbrinck2137 All right, so is there any point, to refurbish the moto inside, instead of setting up a simple mechanic bike gear to change between more speedy or torquey outcome?

[@klausbrinck2137]

@@IUbU 1st: You save electricity and so get higher range. 2nd: You don´t have to use yout legs, you use the motor after all... So, there is 2 points there already. And he doesn´t have 2 electric gears anyway, he just chose to switch to the 2nd gear permanently.

[@lovepreetsinghgill517]

Elimination of hall sensor is in e.s.c. not in motor.

[@jasperyong.5744]

Amazing custom made project, nicely done. Next up build 72v

[@mattclark7941]

Hi please could you do a video on how you wire the motor it’s difficult to see on the video? 👍

yea

Its easy guys, just match the cable colour between bldc motor and universal brushless controller
