Note: The 3D printed brackets/pulley were designed specifically for the bike used in the video, it will not fit any other bike and I will not be modifying it on request to fit to other bikes.
Disclaimer: I do not hold responsibility for any wrongful riding if you chose to build this ebike. It is beyond the legal limit (250w) for an electric bike, which is why I chose to ride it within the grounds of my university.
Got a question about this bike? Check if I've already answered it in my Q&A video ruclips.net/video/IzK121RzC88/видео.html
Tom Stanton You should make vid about how to make a electric scate board 😀
Would be nice if you made some kind of pick up on the pedals, then tie that in to the controller (With the help of your friend) and have it help you push the bike instead of you using the handle. There's commercial stuff like that, years ago even.
What would you charge if l asked you to build the bike in the video, l am serious? l am hopeless with electronics and l do not have access to a 3D printer.
This would have to wait till l relocate, l am not sure when that would be as l am selling my flat and l do not know how long that will take plus l have to find a new place in another town 100 miles away from me just now
is that for a complete bicycle? Torsten
Really nice. I'm professor at the University of Cadiz and I really appreciate your motivation and how you use the tools around you. I will show this video to my students next year during the lectures for motivating them. Hopefully It will work as well as your bike!! I commonly use 3D printer for developing new research equipment in my lab and it is really a powerful tool.
Thanks for sharing it and good luck!
you must be a great teacher. bless you.
You guys ever made any of these EB and exactly what is the total cost?
@@AwesomeBlackDude Could be done for about $200 or less if you have a bike already, probably less if you can weld. It all depends on what kind of power you want, and battery size obviously. But for $200, the power would already be illegal in most places, where I live, up to 250 watts is legal, which is almost nothing IMO.

Thanks for the update info I definitely appreciate it.
The guy in wheelchair could surely use an extra 5000 mAh battery
I'm using a simple servo tester along with the throttle handle. The throttle handle is just a potentiometer which I just solder in for the potentiometer on the servo tester. Works perfect connected to the ESC.
ijustwants that was exactly what I was about to say!
Yea and its 4$
yea, so you desolder the pot and solder in that handlebar pot.
I also thought that there might be a way such as this, but then I thought maybe he didn't because the potentiometer on the grip might of been incompatible with the servo due to different resistance values. Anyway I think that Tom and his pals solution is a far more elegant way of doing it.
wayne murphy it's likely not dependent on absolute resistance, just voltage ratio across the pot's divider.
I'm usign this design for a while now! I appreciate the simple design because when I was looking for an eBike conversion kit I couldn't find any for my fixed gear.
I've found some issues, and I got solutions for:
#0 the grains are not sufficient to hold the pulley on the motor;
fix: make a groove on the shaft for the grains
#1 the belt wear off pretty quickly;
fix: buy some more belts as spare
#2 the belt tensor inner part has broken;
fix: substitute it with a brass one
#3 the bike can't go without battery (because the motor starts when pedalling and oppose force);
fix: put a light weight low capacity battery if you want to ride as a normal bike, then you just don't accelerate
#4 the motor get hot;
fix: mill an alluminium support for the motor
#5 using an ESC the bike can't start when standing still;
fix: put three hall sensors in to the motor and install an eBike controller
P.S.: Be patient for errors, English is not my main language... ;)
Awesome!
A bit of clear nail polish over the components makes for pretty good weatherproofing.
PLA is biodegradable...might want to clear coat with UV resistant clear coat for longevity
I made some PLA-corners that hold the antimosquito net out the windows. 3 years outside - no signs of degradation or anything.
I beleive you will redesign the parts much earlier then they fall apart of age.
The only concern with PLA is heat.
Brian C Hi , please could you tell me what P.L.A means. Sounds like a fighting force.
Polylactic acid (PLA)
en.wikipedia.org/wiki/Polylactic_acid
PLA is not Biodegradable. (Not at-least the way many think it is) Its a Bio-plastic. Very different. PLA has been proven to take just as long to break down as many other petroleum based plastics.
After some investigation...you are 100% correct....thanks

Just a few tips Tom, you might want to try to mount that motor behind the seat below your throttle chip controller but have the motor turned 180 degrees & swap the wires so that it runs in the correct rotation. Also you should make up other size wheel sprockets to get a higher speed example one that is 2/3 the diameter of the black main sprocket on the wheel. Look into making the sprocket thinner by thinking about a V-Belt that is a V-Belt Drive Belt, they look like a cross between a V-Belt & the Timing Belt you are using. That way you should be able to fit both disk break & pulley. You will need to put in aluminium spacers rings that fit over the disk break bolts so that you put these through the plastic pulley so when you tighten the bolts you don't crack the pulley, the spacer only acts to keep the pulley in the right place. These spacers are like spacers on a chainring for a double or triple crankset but they are 5mm.
You can easily order longer M6 stainless steel bolts that use a hex key instead of the star key that you can. These adjustments will make it go speeds of 60-80km/hr or 37-50mph & because you will only use the throttle when you have got your bike up to about 32km/hr or 20mph then you can take your bike long distance if you have spare battery packs in your backpack or if you have a pannier rack on the back. Also you could incorporate a solar panel to charge your battery pack as using it giving you longer range. If you can get 2 of those 10 watt china made You can try these new mods on the next bike you work on which might be a 30 speed touring bike etc.

Very nice video. We reviewed some electric bikes sometime ago. Almost all the bikes had the magnetic disk to detect to motion that would eventually send signal to the motor to assist while paddling.
wow, probably the easiest build i've ever seen. very good engeneering job. maybe i build my own
I'm planning on doing something similar to a Razor scooter. 1,000W motor on that thing will get me going real nice!
did...did you do it?
@@brmotoren9889 Nope, the project dies when I realized that I have no good way to mount the motor :(
@@LazerLord10 well its still nice to see people being creative!
@@LazerLord10 You should look at my video, I placed the motor elsewhere. Maybe this will give you some ideas !
Here it is : ruclips.net/video/Y1Vsda0HCHo/видео.html
Good Job Lads. It's great to see young minds creating useful things.
I build custom Motorcycles called Bobbers.
You are off to a great start if you continue to develop the Electric Bike for a broad range of purposes.
Try to think of a Trike build for seniors or disabled people to get around urban areas. Could be a winner if the motor and battery last long enough to be useful in a trike for running errands.
Thanks for sharing.
very educational. I had no idea cringe was an adjective.
Do R/C! I now lol
Nice project indeed.
I had my doubts about 3D printed parts in multiple pieces but it worked well and was a simple yet effective design (the best ones always are).
Could you make a video about how you designed the pulley gear thing on the rear wheel?
Nice project, I'm using a printed pulley on my electronic longboard as well! Holding up nicely. BTW, you don't need the arduino, you can control the vesc directly with voltage. Just change the settings using bldc tool. Less failure points that way
So impressive! i never imagined 3d printed parts can take the stress of the powerful 150kv motor! This young man has a bright future. Very promising. Liked and Subscribed !
Brilliant as usual! I made an electric longboard last year, lots of fun. I cringed a bit at the wobbly riders with no helmet, please be careful. Will have to see about doing this sometime, looks like a great project, and much cheaper than a ready made one. Yet another reason for a 3D printer! Good luck in hour studies.
Yes my housemate has since purchased a helmet. Thanks Dean!
You could've taken the easy way around the analog to digital conversion and just bought a servo-tester for RC servos.
You could have removed the potentiometer in the servotester and soldered in the wires from your throttle.
And that box is probably not water proof at all.
You need to cover the cirquits in liquid tape or other insulating sticky stuff aswell as using a rubber grommit or silicone sealant, but you'll find that out soon enough and you can make improvements :)
I built one of these years ago. If you gear an internally geared hub and run the power through the chain you get all the advantage of gearing. Plus you can hide the motor in the width of the bike. I originally had a derailer on it, but the motor kept making the chain jump during gear shifts. Mine's mounted on a folding bike that I can take on our commuter rail even during peak periods.
This is essentially a mid-drive style bike . you would get more torque from a direct drive system aka hub motor . you should make a new housing for the motor with spoke holes and make a hub motor . Now that would be cool . Having said that this is a very cool bike .
what about the induced current from the motor flowing back to the ESC when you pedal? is there a chance of doing damage to it?
rmay000 wouldnt it just charge the battery?
+Lacksi Yes the ESC (called a VESC) I'm using has regenerative braking.
Ahhh! That's very convenient. I wasn't aware there were ESCs with that functionality for a reasonable price.
I would rather use some kind of freewheel, instead of directly attached pulleys and ditch the regenarative breaking, because:
1. With your setup when you stop applying power the motor rapidly becomes a dynamo and stops the bike, so it is bad for milage
2. Because of 1. the belt could slip and wear faster
3. Regenerative braking with your current setup is dangerous, because, even that you are using ESC that supports it, you have the 6 cell lipo connected directly trough the non-balanced main battery leads which should be used only for discharging. Chargibg should be done trough the balanced leads instead, otherwise the battery will disballance and you might damage it, or get it on fire on some steep downhill.
4. ESC gets hot during climbs and even hotter during regenerative braking on downhills and may not have enough time to cool down and melt the case.
5. Number 4 pretty much applies to the battery as well, but it seems pretty well-rated one
I was about to ask about how the battery handles the charging but it seems you answered that for me :D
1:11 has anyone noticed something drawn on the sidewalk?
I think it's tar from resealing the cracks in the road.
Bravo ;)
Lol
Oh uh I see lol
i like very much that this channel turns from racing quad only to education stuff and fun... well done Tom!
Haha thanks!
You are awesome, I think I should throw my useless Engineering Degree to dustbin after watching this because I haven't learned anything valuable and I can't even create some simple stuff. Felt really ashamed of my self, I should watched this video 6 years ago.
you really deserve more subscribers
Simon Vance de
You can't coast a fixie. It's fixed. This is single speed. Great build and well done, tho.
yh ,fixed is not fixie ,fixie bikes are for hipster bellends too lol
impressed that that large pulley held together
Very nice bit of design and printing
Cool project, but get the nomenclature right, it's not a fixed-wheel, it's a free-wheel or your legs would have to keep turning all the time.
Very nice job! Please update us on the longevity of the bike and the practicality of it. I would also like to see its efficiency (Wh/km).
Yes I will be making a follow up video over the next couple of weeks. I don't currently have a watt meter, but using my charger, I have calculated that on average it uses approximately 950mah/mile at 20mph without pedaling (so if taking the voltage as 22.2v, that's 13.12Wh/km) and 650mah/mile at 20mph with mild pedaling (8.97Wh/km). Thanks!
StantonFPV That seems like a very good efficiency for what it is. I wonder how much the assist by pedaling reduces the number.
BSC4PE knowing Lipos under that sort of load i calculate a 5 min runtime on full power for 100% of the time using that battery
Probably the most simple designed set up ever. Nice job!
Tom that is awesome but make a generator too that will charge the battery during riding it (you can position it on the other side of the wheel). ENDLESS POWAAAARR
that's good & simple can you tel me how much total spend on everything ? tank so much
briliant tom ! i am from Brasil , i liked your videos 👏👏👏👏
Thanks Marcos!
i
how isn't this one of the top channels
Excellent project very neatly carried out. I keep trying to think of a reason to buy a 3D printer perhaps this is it.
I've very recently converted my wife's bike to electric assistance using a commercial available system. This uses front wheel drive and a pedal assist feature which can be varied in steps depending on how steep the hills are. I'm about to convert my own bike too. We're experienced cyclists and it's our age (late 70s) that's making us resort to artificial means :)
The system we're using is from Cyclotricity and is around £500 so yours is much cheaper (we already had the bikes). A complete front wheel with motor hub is only £129 so it might be worth looking at for future projects but the motor is 36v/250w.
Just a warning. The legal limitations on electric propulsion for public road use of pedal cycles in the EU are for a max power of 250 watts (less than than my aeroplanes!) and 25kph (15.5 mph) so be careful! I also think having a simple throttle rather than pedal assist (which is a bit more sophisticated) may be legally problematic as well but not sure.
Great project though and it does you credit. Good luck with your studies.
Hey would you be able to share the code for changing the analogue signal to digital? I am actually trying to make an electric car using the VESC!
If you're using arduino, analogRead() is good enough to get a digital value by itself, otherwise look up the data sheet of whatever chip you're programming (I'm assuming you're using a chip since you asked for code), most of them have an ADC built in. The code consists of setting the prescaler bits in the ADC register of the chip, and then enabling the ADC clock. Then you can read the value put into the corresponding register. Should be roughly the same for whatever you're using. I used AVR (the same chips in arduino controllers).
This is a good tutorial if you're not familiar with the type of chips I'm guessing Stanton's EE friend might have used for analog to digital signals which require coding:
www.avrfreaks.net/forum/tut-c-newbies-guide-avr-adc?page=all
google "arduino servo knob"
This is not really how you typically write code but I cramp everything in one line of code. (not good coding practice)
It read the potentiometer value that is varies from 0 to 1023 and scale it back to 0 to 179 then write it to the servo motor.
void loop() {
myServo.write(map(analogRead(potPin),0,1023,0,179));
delay(10);
}
----- EDIT -- here is the basic code you will find online
// include the servo library
#include
Servo myServo; // create a servo object
int const potPin = A0; // analog pin used to connect the potentiometer
int potVal; // variable to read the value from the analog pin
int angle; // variable to hold the angle for the servo motor
void setup() {
myServo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop() {
potVal = analogRead(potPin); // read the value of the potentiometer
// scale the numbers from the pot
angle = map(potVal, 0, 1023, 0, 179);
// set the servo position
myServo.write(angle);
// wait for the servo to get there
delay(15);
}

thats all i could find, sorry
your doing so well these days. I feel a bit proud. keep up the great work Tom.
Thanks man! Feels good to be back to making RUclips videos again haha
@@TomStantonEngineering I would like to see your kit series produced, cottage industry style. Maybe you need to make friends with a production engineer about your age. Add a couple of friends to handle the plastic work, and the circuit board, and off you go.
Tom, if you want more durable components, you can set the 3D printed parts in plaster of paris, then cast them in metal.
Does it spin the motor if you are just pedaling without power? Does that mean pedaling takes more force ?
radry100 yes it does
That's where ya need 1 way fixie cog so it freewheel s the motor
This way however allows for regenerative braking
annihil8ted don't u start..... regen braking lmfao on a bike ffs on a car might do something but when ya gonna brake for an hour to charge batteries lmao
Are you serious? They have regen braking for even longboards...I'm guessing you've also never done a bike descent? Also the purpose was never to fully recharge the batteries. The point is to stretch the traveling distance. Even an efficiency of 15% is giving an extra 1.5 miles on a 10 mile ride.
Have you released the 3D print plans ?
I likeyour design to wish you send blue prints to me
Maybe good for the summer, but for rainy days off limits, also make some self charging battery
Brilliant idea! Laws in the US are harsh against this stuff, otherwise I'd love to make one with a higher-torque motor.
make it a dual motor
better to just increase the size of motor and change the pulley ratios.
Marcus Christensen that plus dual
His current motor can deliver up to 2000W, and the vesc can also handle much higher voltage. So all he needs is a battery with more volts... because with 2kW you could reach around 50mph...
Pryside make it dual motor for 100 mph
I dont think physics work that way, haha :D
Legend
That's some nice neat work boyos. Simple, well thought out, nice little details. GJ with everything. Can't wait till I can afford 3d printer =D
you should market this dude such a compact bike
Sam and niko anyone ??
Edible TNT Yup!!
Hey, tom I like this. Awesome work doing.
Thanks!
Tom, I designed aluminum gear pully. I bought ESC & BLDC motor, but the problem I am facing ESC has little delay for start everytime. I used servo motor control circuit, I rotate the knob then it produce little sound for 3 sec. then it start. Is there any circuit which start the motor immediately without delay. Thanks for sharing information.
Tom Stanton ok
The world is a better place with kids like this. Just as long as a weapons manufacturer doesn't scoop him up! :)
peddle-power tanks
The speed controller takes PWM which is an analog signal since the information is in the variable time between two signals.
As I understand there are Multi copter ESCs that take digital input named "Dshot" .
Keep up the good work.
nice, but as has been pointed out it is a motorbike under under EU laws.
Brexit will allow the UK to set its own rules soon, I hope we can get the limit up from 250w to maybe 750w like the states.
All I have read says regeneration is not worth the effort - my plan is to have a small diesel or petrol generator charging a battery 'off line' :)
Paul Perrin if you want think green ..go hydrogen
Hahahaha! laws like these are meant to be broken! Sorry to disappoint officer, but this is my tail lamp generator.
Paul Perrin nah noone cares about the EU law if they catch me i just have to pay a fine
lol they will more likely lower it
Paul Perrin
Helo, i likez you, pleaz send adress so i can sedz you a reel sodder iron. Keep work good.
Ratty from InsideFPV i'm going to call soldering iron a soddering iron from now on
pretty neat ! :).In case yo exceed the motors top speed, I would consider a one way/over run clutch bearing in the sprocket on the wheel. So it will free wheel instead of over running the motor and possible frying your electronics & a speed sensor on the wheel to cut out the motors power, if the speed exceeds the motors max speed, no need to waste your battery
tom looks like a child who'd been caught taking 1 more cookie
I'g get some thin sheet aluminium metal and cut a couple of at the wheel pulley size disks out of it to mount on and reinforce the wheel pulley. Torque over time on the pulley plus heat friction caused by the belt is more likely than not going to cause the pulley to weaken and break.
I was told that rc parts will never work when I wanted to build an electric bike a few years ago. You certainly prooved them wrong
nice to see young people using their skills , well done.
Most important for efficient travel? High pressure low rolling resistance tyres are a great addition.
great video guys. well worth watching. you took a lot of the mystery out of ebikes for me. I know people who have paid $5000 for things to do the same, and $1500 for conversions of mtb's. the only reservations I'd have would be of how far laterally the motor protrudes to the left.
The VESC is a great bit of kit, loving the one on my GoPed and have a VESC 6 on the way soon.
Definitely the best ESC out there for electric powered human transport!
This is pretty much what I want to do on the front wheel of my custom drift trike I built, and you have also fixed the main pulley to the spokes just as I was thinking of doing so proving that it works too, should be a damn site cheaper than a electric hub setup, nice work :)
Tom, zit down with your electric friend and think out a way to use the forward motion force to charge you battery (electric brake initiated big the hand brakes ) will keep you longer on the electric support :-)
Excellent work. I would double size of motor and way bigger battery pack and then it's a solid unit. Very clean build. Cheers
Great job. I'm sure the esc cost a pretty penny but it looks like a nice setup. I doubt you'll have any over-heating issues, considering the size of the heat sink on the esc, however you could always turn the esc around so the heat sink is facing forward and getting hit with direct air as you move forward.
Keep up the good work and keep the build videos coming. I'm sure the 4 of you could come up with some pretty neat stuff as aspiring engineers. 👍
Next I would suggest to do this with a recumbent. It's so much more fun to ride.
I was planning on doing something like this over the summer before I head off to university. It seems worthwhile if I get Into Warwick since there are bike racks everywhere. Im probably gonna try and do it on the cheap using ebay parts and a 24vdc electric scooter motor.
Very nicely done young man, I've only just discovered your channel & after 2 videos, I'm fully subscribed. Best wishes from Australia 👍🇦🇺👍
nice project i made one with a friction drive, works pretty well and is easily removable from the bike. Though efficiency id imagine is not the best neither is tire wear. My bike has disk breaks so sadly this project wont work. the motor is an 800kv 600watt brushless, if you push it too hard and miss treat it, it can get pretty warm maybe close to 100c (when it burns my skin its to hot lol).
Brillant ! tom ! AWESOME !
Thanks Dani!
Thanks for the information
That's really great, that the 3D printed parts hold up under the load. I might need to experiment with that! Hope you will post follow ups to this after some use, to see how long the pulleys last etc. Well Done!
Yes I will be making a follow up video over the next couple of weeks. Thanks!
Man I've been wanting to do this, but we have a ton of hills here. I've been looking into car transmissions for an idea of how to get a 2 to 3 speed simple transmission for hills and stuff, but I don't have the equipment to make one. Keep it up! I really like seeing this!
nice work! I have done with my e-scooter project. Will be tons of fun to build another e-bike like this.
Amazing build
That bicycle is slick!
You are a,stunning example of youth on the right track.
Well done Tom!
Just to make you feel better, all anodised or painted brake tracks wear off within a few rides. Even the top end alloy wheels. It's best for the manufacturer to leave it unpainted.
super cool Tom, I'm working on a build video now. Thank you!!!
Awesome! Subbed and look forward to seeing it!
One of the best designs I've seen on the internet!
A good use for a 3D printer. Prototyping is probably the best you can hope for in the 3D world. It's a slick technology , but too slow for production.
Handy and smart people are cool! Great job, two thumbs up!
Good job, and great thinking. :) But the motor you are using has a rated for high speed, and not torque. If you change your motor you will get a much better result with the same amount of wattage.
18:56 beautiful contrast
This is awesome stuff Tom, I wish I had a 3d printer! I would love to make this upgrade to my bike
Nice effort Tom , and for us non techies the 3d printing is very interesting. good job sir.
Well that are some good quality videos for a ginger. Hahah just kiddin. Well done!
Wow, that is one small 3d printer. That motor mount looked large when printing, then I saw you holding it in the next frame.
Pretty neat project. The "throttle" handle you would essentially just take and make a variable resistor/capacitor circuit and something between it and the controller since you said PWM, most brushless DC motors can have a controller like that but it's interesting what you can do with microcontrollers these days like your friend using an Arduino. The cooling fan was a wise idea but I wonder if there's a way to make a protective cage for it as well if you were to wipe out causing damage to the motor... or maybe making a helically cut bevelled gear setup instead of the belt. Granted, the geartrain would be somewhat heavier and noisier than the belt but at least your motor isn't sticking out like a sore thumb.
Tom Stanton I really thought you was goin to do a burn out at the start lol. Good job works well with that other gear on.👍🏽
My biggest concern is failsafe. Suppose the arduino has a hiccup. You could end up with the ESC giving full whack. You're only option then would be to pull the power lead.
For sure that is a concern of mine too. I will most likely build in a switch that can disconnect the esc signal wire from the arduino as the ESC has a failsafe shut down if it doesn't receive a signal
elegant design Tom,
i found XL6009 DC-DC Step-up Module interesting.i hope u can use them in order to provide stable power supply to li ion bty as cheaper source of energy back from motor.rest the model is pretty nice.nice job and well implemented.
thats is cool, you should fabricate kits and sell them, ship them all over the planet. Good job.
sir clive sinclair will be impressed. his version just had a brushed motor with a rubber wheel on the end that pressed onto the back tyre.
nicely done! 3D print on point!
excellent video with excellent source info
I'll probably make a goped/e-scooter myself. Cool bike, btw. :)
This is awesome! How can anyone dislike this video!
