I've just realised it may seem like I wasn't wearing a helmet, but it turns out the GoPro is mounted to the helmet and therefore I had to briefly remove it to check the GoPro battery! Thanks
I know people get bent out of shape about helmets, but bike helmets are generally rated for falling of a stationary bike, or maybe walking pace. They offer little in the way of protection at 45kph, especially vs a tree. You might want to look at using a helmet designed for a motorbike... or just not wearing one and enjoy the wind in your hair.
Tom I have to say that your ebike videos have helped me more than any other set of ebike videos. You're version is closest to what I want to build and your insight and tips are outrageously helpful. Cheers to you mate.
Tom Stanton Tomorrow will make a year that you've had the final version (at least according to your video blog) of your E-bike. How has it held up? What would you do differently? How often do you use it anymore? I have a regular bike with multiple gears that I ride a few times a week, I am considering building an E-bike for myself one day... are there any tips you would add to your Vlog having gained all this experience to a novice maker.
Thanks for km/h Tom. I know it was as mistake but much more comprehensible for most of us cyclists (global perspective). Keep it that way! That's a real machine well done!
I have to say, I'm extremely impressed, you've articulated your adventure beautifully. I really appreciate how you're open to disclosing problems & your thought processes to fix them. All the very best to you (from Australia) young man, you're a champion. 👍
Hey Tom, I can't recall if you ever mentioned much about those batteries in any of your videos? I'm considering building something similar to this myself, and I am very interested in how you wired up those batteries and how you balance all the cells! What charger do you use?
Foooooookin hell! That is amazing. I built a 1000w hub fastest I've had is 56kph going down hill and it felt like 100kph. This is next level. Love it! Your acceleration is scary
Please test it out on a paved flat road so I can compare your top speed to my personal human powered best! It looks like a lot of fun. Also, can you give an estimated range for the batteries? Can you also charge the batteries by pedaling the bike with the wheel off the ground?
In the video he did say that the batteries will do about 15-20 miles (24-32 km) Also, in one of the earlier videos he reckoned it'd do 30-35 mph (about 48-56 km/h) on a decent bit of path, and in the video (going up hill) he pulled 45 km/h (28 mph), so if you can manage that, Tom's E-Bike has got some serious competition (lol)
And that was even bloody uphill at an approximate 9% incline... I've seen model aircraft with less power (approx 3.7kW) lifting up themselves *and* a 7m wide 1:3 scale glider. 4kW is a s*load on a bike!
It depends heavily on conditions. We don't know how soft the trail is or if there is a gradient. He noted in the video that the gradient is GPS based... which is just about worthless.
My bike is is chain driven. It has take lot of work to get chain line straight, but now it works. I have brushed motor and good torq, easily wheeling in 18th gear.
Green Silver with motor braking or regen turned off then there will be only a tiny amount of resistance. You’d probably notice the weight of all those batteries more
Great to see this bike up and running. I use the same Vesc6 Tampa on my 12s4p dual direct drive mountain board. You could totally cool the motor by adding some vents in the housing and then use a kitchen splash screen mesh wrapped and then glued between interior walls to protect against dirt and other objects from entering. I have done a similar thing for my Trampa motors. The print walls end up looking printing like this: | wall | mesh | wall |. I've found that the spinning motor itself is able to produce enough airflow to actively cool itself. Also its great you are going to 3dprint a cover for the Vesc but Tampa also provides a rubber cover which would also do the trick. looking forward to seeing more progress!
Wow great job now that's an electric bike just take it easy in the woods at that speed especially with tree roots etc. Love to see a test run on a quiet road good job enjoying the videos keep up the good work.
Can you do an electric skateboard/longboard next? A 3d printed system would be very unique and this project would seem to suit your engineering skills perfectly!
Hey Tom, really great video to the series of updates on version 4.0. I spent all day today getting cheap prices on all the parts to do this myself using my Carbon Fibre 26" Mountain Bike, a 12s 8p battery 50.4v 20 Ah & I found a 44V 48V 50.4V 12S 150A Continuous BMS / Balancer. The build is quite expensive. I was wondering, the motor drive pulley 20T & motor driven pulley 40T did you go with HTD 5M 15/20/25mm Width & the 20T to 180T wheel pulley did you go with HTD 5M 15mm pulley's & belts? They are 5mm pitch 20T 8mm bore pulleys & I'm guessing you used 5mm pitch 20T & 40T 10mm bore pulleys because I've not found a 5mm pitch 40T 8mm bore pulley yet. Tom, I don't have access to a 3D printer to make the 180 Teeth 5mm pitch 16mm internal diameter wide plastic wheel pulley that mounts onto the back wheel. Is there any way we could work something out where you print up a pulley & I can pay you for materials & shipping using Western Union? I can make up all the aluminium brackets & frames to put it on, I just need the pulley with it's holes ready for tapping M5 so you would only need to locate the holes with a 3mm drill & I can sort the proper tapping drill size & threads. Thanks. Mark, Perth, Western Australia
It has pretty similar performance to a Sur-Ron. the Sur-Ron has a longer range interesting. the Sur-Ron has forks and rear suspension similar to motorcycle. same with the wheels and tires. the Sur-Ron also has regenerative braking.
Looks very good indeed. I would be inclined to cover the primary and secondary drives near the motor for when winter comes and you ride with trousers. You wouldn't want them dragged into the pinches between the belt and any pulleys.
Seems like you figured all the Electrical/Mechanical glitches out. Well done. Seem to ride well. Would have liked to see the top speed and wattage on a level/smooth asphalt or cement non dirt or gravel road.
Cant find words right now, but one thing for sure, you're awesome ! I am looking for ways to also do it Id love to have this setup. Way more convenient than getting a heavy wheel with motor.
Hey I'm a recent subscriber, binged watched a few project videos of yours but the issue with Lenz's law drove me to commenting. It's something that makes perfect sense when you think about it but I honestly would have never thought about that if designing a similar motor mount! You learn something new every day eh
Excellent build, very impressed. How feasible would it be to have a display with real time data mounted on the handlebars?power/speed/voltage/remaining distance etc?
Great video, I am not into bikes, not even electric bikes but I do enjoy your technology and the detail of the information you put into your projects so an excellent video to watch for the information you have provided and visually a great day out anyway 😊😊😊😊
Have you thought to use two spider gear vertical, one mounted on the motor and one one the back wheel? I'm a physicist not an engineer, but engineering is a very tempting field of science, so it's just an idea and I would appreciate if you answer...Thanx in advance and your idea for the E bike is the best I've seen till now!
This bike is incredible! Awesome build, would be worth while to get a full face helmet, this bike is pretty quick and it could save your bacon if you crash!
I’ve also had my ebike handle grip separate from the throttle body and it slipped off the bars. It would be good to check your design, I dremmeled off the last 5mm of the handle and put on an “ODI” lock on grip so even if the handle breaks again, it’s stuck on the bars
Its hartd too imagine this project really came outr thisd great! Have good fun to ride it and you can get your self a basic bike computer which can come very cheap and also gives you real time accuate speed too.
Pretty awesome bike. Now just hook up a dyno to pull charge off the wheels/use regen and dump that juice back into a large cap. bank. Use that cap bank to handle initial acceleration to prevent voltage sag on the battery.
Excellent video and work Tom! You're an inspiration mate! I an designing my own ebike and your information is so valuable! Thank you so much for sharing Sir!
Do another one of this E-Bike but place a motor that will regenerate power whilst running. Maybe put it in the front and use one way diodes to prevent backflow of electricity. Also please program the motor that is driving the wheel to also regenerate power when you are off the throttle
Hi from a fellow engineer from Spain What is the configuration of the battery? (Like 5s2p and so) Great proyect, for sure the cleanest here; and also well explained. Thanks in advance
This is super cleanly done. Excellent job! Not sure if it's possible with your current design, but some kind of a clutch for the motor would probably help so that you can pedal when you want to without fighting the electric belt drive system.
The whole project is clean and the result is stunning. I would propose a new version, which has a ordinary chain hooked up to the biggest cog (there are cassetes with 50 tooth now) of the rear cassette on the right, instead of the rear pulley + belt. Essentially it will have 2 chains on the right side. One downside i guess it would need to have an ever bigger reduction on the right side (will probably need to be transferred to the left side also) from 2 to 1. Also you won't be able to use the highest gear which will be always reserved for the motor. This way you eliminate the need for a pulley construction and belt system. Imho a quality bike chain is enough from experience i have with 1500W off road system. Hoping you see my comment!
Thanks for the proposition! I had actually considered a similar idea, however the issue is that the pedals will always spin when the motor is running. I know you can buy freewheel pedal crank sprockets for ebikes, but I'm not sure they'd fit on this bike as the frame only allows a very small crank sprocket.
Yes you are correct, the rear cassette freewheel is not helping in this situation. For simplicity sake and solely for assistance on pedaling, i am thinking to create a similar system as i am fascinated with that. Best solution to this is indeed some kind of freewheel cog on the crank.
Best one: your deep taking breath before starting the hill climb ... felt really like you were preparing doing that performance on your own - not the battery.
Great job, I envy your design skills. I would love to build a bike like this. I have been looking at suitable bike and motor option. I want to try fitting it to a bike with mid gears instead. Also maybe you should try to design a two speed gearbox so I don't have to.😉
Nice job! But i do wonder just how long it will be before electric bikes will require registration, licensing, insuring and driving licence? Seems to me that a decent electric bike will out perform a lot of mopeds etc that do require all of the above. I am sure the authorities will be onto it before too long, but i think they are busy at the moment trying to decide what to do with the airspace below 400 feet .
It’s not pedal assisted. It’s not restricted to 16mph. So technically it is a moped. If caught he could be pulled up for riding without MOT, registration, insurance, a helmet, and all the things it’s missing like brake lights, indicators etc, as well as riding where motorbikes aren’t allowed.
Yup, in reality, many things are illegal, but if they aren't enforced they are in essence legal. Keep in mind that "not being enforced" is not the same as just "not getting caught", as with these bikes you can ride right by police and they don't give a shit unless you are flying through packed pedestrian areas at high speeds.
This is a moped. There are multi classes of ebikes with each their own restrictions and freedoms. The class system depends on the nation (and some countries only have one class), but this wouldn't fit any of them.
How much would it cost to make this I haven't got the technical know how on how to take something like this but if you ever go into manufacturing a kit like this I would buy it if it wasn't to expensive it looks a lot better than other kits I've seen.
I've just realised it may seem like I wasn't wearing a helmet, but it turns out the GoPro is mounted to the helmet and therefore I had to briefly remove it to check the GoPro battery! Thanks
Do a burnout!! :D
Do a barrel roll!!
Mehh You should get a safety tie like Colin Furze.
I know people get bent out of shape about helmets, but bike helmets are generally rated for falling of a stationary bike, or maybe walking pace. They offer little in the way of protection at 45kph, especially vs a tree. You might want to look at using a helmet designed for a motorbike... or just not wearing one and enjoy the wind in your hair.

Think that is the best ebike build I ever seen. Clean, cool and clever!
Thanks!!
Yes I must agree I want one I prefer the other model looks a bit more sexy
Its a hub motor, discrete and almost silent

Thanks for km/h Tom. I know it was as mistake but much more comprehensible for most of us cyclists (global perspective). Keep it that way! That's a real machine well done!
Yes Metric all the way, should keep it that way. Only yankies do MPH. :P
Outstanding engineering and development. Humble presentation of a great work. Thank you.
Brilliant. I want one.With only one leg that works I can see the benefits of an e-bike....especially one as well engineered and thought out as this.
I have to say, I'm extremely impressed, you've articulated your adventure beautifully. I really appreciate how you're open to disclosing problems & your thought processes to fix them.
All the very best to you (from Australia) young man, you're a champion. 👍
Great job, you should add a USB port to the battery pack so you can charge your Go-pro when it gets low.
Yeas
Hey Tom, I can't recall if you ever mentioned much about those batteries in any of your videos? I'm considering building something similar to this myself, and I am very interested in how you wired up those batteries and how you balance all the cells! What charger do you use?
I was waiting for this demo. An achievement indeed. The speed is pretty high. Your design is above the average Tom. Thanks for sharing it.
dude u deserve to have your own electric bike company !!! this is a great job love you Tom !! from Sénégal !
Atleast like sell it as a kit or something.
yeah sure !! something like that would be awesome !!
Foooooookin hell! That is amazing. I built a 1000w hub fastest I've had is 56kph going down hill and it felt like 100kph. This is next level. Love it! Your acceleration is scary

That engine just peaked at 5 horsepower, quite impressive.
Awesome job Tom! That looks like a quality speed controller you chose as well.

wow that looks fun! I've so got to build one :D
Not as much fun as my Suzuki
When are you selling kits for this eMotor ? ⚡️ 🚲
Never
Isn’t 800 watts for sustaining 18-20 kph a bit too inefficient????
Pro cyclists average 40km/h on 400 watts in normal conditions
I get about 220w at around 30km/hr on my ebike. Maybe your watt readings aren’t calibrated ?
My bike dont need that much either. Under 200w @ 20kmh and goes 40kmh whit 36v and 15amp current limit.
It depends heavily on conditions. We don't know how soft the trail is or if there is a gradient. He noted in the video that the gradient is GPS based... which is just about worthless.
It's mph. Not kph. He left a note at the beginning say he doesn't know why it's displaying kph. He set it to mph.
That rear pulley is very clever, never would have thought 3d printed plastic would handle that application
I love seeing the progression of these. Also your motor design is so awesome. I love it. Id like to do something similar for my project.
Tom by the time you reach version 10 you'll just have a zero motorcycle.
Wow, I wish I had such beautiful places to ride as you do.
yeeeeaaahh! So much powerrrrrrr!!!!! nice job guy!
Your log shows kph because it knows that kph is superior.
kph just means you think your going faster. :P
na, its just the better unit, esier to convert into its lower units and is much better for phyiscal calculations

This version of the ebike is really great, it made me start an electric minibike build ;)
Absolutely wonderful presentation! Great job!
What happens if god forbid, you have to pedal it?
Can you disengage the drive system so you don’t have to pedal against the motor and belt friction?
Green Silver with motor braking or regen turned off then there will be only a tiny amount of resistance. You’d probably notice the weight of all those batteries more

Cheers Tom. The rocket is still some months away from launch. Love your channel by the way, you have some very nice projects. Keep up the great work!
best diy ebike i've seen so far...wouldn't mind building one exactly like yours
To prevent overheating of the motor, you should cut out ventilation holes on the motor guard (or design a new version with holes).
Maybe an easily cleanable mess cap of some sort???
Hey Tom, really great video to the series of updates on version 4.0. I spent all day today getting cheap prices on all the parts to do this myself using my Carbon Fibre 26" Mountain Bike, a 12s 8p battery 50.4v 20 Ah & I found a 44V 48V 50.4V 12S 150A Continuous BMS / Balancer.

Hi from a fellow engineer from Spain
What is the configuration of the battery? (Like 5s2p and so)
Great proyect, for sure the cleanest here; and also well explained.
Thanks in advance
It's a 12s5p battery. So 44.4v 15ah. Thanks!
Wow! A real life application of Lenz's Law.
This is a brilliant piece of engineering and ingenuity. You young man are going places.
When are you going to be producing a kit to purchase ?
This is super cleanly done. Excellent job!

Very impressive - well done.
Say, could you implement a regenerative/electromagnetic braking system where the motor charges the battery when coasting on inertia?
Awesome bike! You really got some speed on it!
Very interesting build, thanks for sharing.
A lot of power for such a compact motor, but I don't think I could put up with the noise for very long!

It would be brilliant if you had a summer school workshop !
Hey, is it possible to use that data overlay .fit file with final cut? Thanks :)
Great build!
Unfortunately stuff like this wouldn’t be legal to make oneself where I live...
lenz law is a formula to figure out induced current, its eddy currents that act on the motor to counter it spinning.
Best one: your deep taking breath before starting the hill climb ... felt really like you were preparing doing that performance on your own - not the battery.
Great and clean work.thanks for sharing your experience..
You should add regenerative breaking to change the batteries mid ride!
Great job, I envy your design skills. I would love to build a bike like this. I have been looking at suitable bike and motor option. I want to try fitting it to a bike with mid gears instead. Also maybe you should try to design a two speed gearbox so I don't have to.😉

Nice job! But i do wonder just how long it will be before electric bikes will require registration, licensing, insuring and driving licence? Seems to me that a decent electric bike will out perform a lot of mopeds etc that do require all of the above. I am sure the authorities will be onto it before too long, but i think they are busy at the moment trying to decide what to do with the airspace below 400 feet .
They already do lol if it is over a set amount of watts or can go above 15mph.
It’s not pedal assisted. It’s not restricted to 16mph. So technically it is a moped. If caught he could be pulled up for riding without MOT, registration, insurance, a helmet, and all the things it’s missing like brake lights, indicators etc, as well as riding where motorbikes aren’t allowed.
This bike is not street legal.
Yup, in reality, many things are illegal, but if they aren't enforced they are in essence legal. Keep in mind that "not being enforced" is not the same as just "not getting caught", as with these bikes you can ride right by police and they don't give a shit unless you are flying through packed pedestrian areas at high speeds.
This is a moped. There are multi classes of ebikes with each their own restrictions and freedoms. The class system depends on the nation (and some countries only have one class), but this wouldn't fit any of them.
Downhills were invented to go FAST! >8^)
I'm enjoying your channel .... The bike stuff in particular ..... 👍👍
Noyce! Have you considered designing a motor cover with vents for cooling?
Eddie currents
From the aluminum plate?

You should lift the motor further away from the frame to stop the currents being induced their too.
How much would it cost to make this I haven't got the technical know how on how to take something like this but if you ever go into manufacturing a kit like this I would buy it if it wasn't to expensive it looks a lot better than other kits I've seen.
sound is awesome
Very impressive.
Awesome job, now for the regenerative braking into some ultra caps :)
