Building an electric bike isn't easy, especially when using unconventional electronics, such as a drone motor. After 3 years of development, I have a bike that I'm finally happy with... but who knows what I'll change next...

You have to rewind those cheap motors anyway with thicker wire for efficiency, and to modulate kV, dependent on the windings-number.

Mate, you are probably not reading comments a year after the video is realised ... but for real, what you are doing is inspiring. You provide a lot of honest knowledge to the public, and on top of it share the fruits of your journey. You upload the results, the final CAD files, the methods and the means. Hats off to you, sir. May your channel be as plentiful as your great work.
yes thank you to him, i am building one right now
@@bhx7527 how did it go? did you succeed?
This was absolutely fascinating!!!! I LOVE all of the thought and consideration that went into your various iterations of the project.

And a usefull brain and not a waste off skull space. That being said, i don’t see any use for the pedals anymore.......

"This is my homemade electric bike. It isn't powered by a battery, instead a turbine fed by a pressurized tank creates the electricity needed to turn the motor. The fuel efficiency is pretty good as I only have to get off and pump the tank full with a bicycle pump every 30 feet."
Maybe you could mount the pump to a flywheel, so you can use the pedals to pump the pressure tank.
@@kalleguld well that sounds like a regular pedal powered bicycle

The closest you can get to this is using liquid nitrogen engines.They are real and the energy density is about the same (terrible) magnitude as Li-ion.
I love Vedder’s speed controller project, it was a big inspiration for my university capstone project. Thanks for sharing your whole process, failures and successes alike :)
This is one of the most useful DIY electric vehicle videos I've ever seen. The explanation of gear ratios and kV rating was very helpful.
8:01 that edit was absolutely amazing
Ikr its simple but cool
I went to type this exact thing but thought I’d check the comments first. Such a slick edit!
Bro I didn't even notice
It was okay...
"I Know most of you are engineers" Sir, i'm a useless 20 year old.
I wouldn't say you're useless ! You're at the beginning of many challenges. You have many options and choises. Choose wisely, do the right thing !
Your youtube channel shows evidence to the contrary, You are quite a skilled engineer of digital vehicles!
*_useless 19yo noises_*
Hahahaha! I'm a useless 23 year old!
Bah, think of yourself as a battery looking for it’s pack.
Interesting watching you work thru all the unforeseen issues as you went along. Don't know anything about companies who build electric bikes for sale, but if TOM decided to go into the business, they might find they will eventually have some stiff competition in the future.
I could see how this would create a huge amount of gratification. Great job.
8:04 wow, that was smooth
yup
Amazing engineering work Tom! Love the dedication to the project and your constant strive for optimizing performance! Just don't forget about safety, your batteries are aimed directly at your valuables!
How to make freewheel? Much needed for this project!
Your intellligence facinates me immensly. I can't stop watching your videos.
Very well done, i like that you included the failures, well i believe failures are the only way you can learn the best ways that work. I am impressed and certainly think you have all the right stuff to succeed in any project you choose. A lot of what i see you working with can be "reverse engineered" into other fields, i wish we were neighbors i need your expertise to combine with my wind turbine projects to make power like nobody else can.
The editing in this video is incredible, particularly the transitions. You also did a great job of packing a ton of clear, concise narrative along with explanations and data into just 14 minutes.

Not boring! Good spec coverage and some really great engineering skills and tips! Cheers . . . 🧐🤓
you have learned a lot by doing „mistakes“ - While my long time in sports car industrie I really liked to have engineers like you around me - which burn for what they do. Talented and inspiring !
Sensational, thanks for sharing - clearly a lot of time spent improving, and we all get to benefit from your past issues!
3:06 : haha, perfect timing with the jet aircraft going overhead.
Seen this before, loved watching it from the start again. Amazing the work that you've done and with a 3d printer
well done. A good understanding of electric engineering and hands on skills simultaneously
Tom. Thanks for this highly useful video. It progressed quickly but not too fast. You explained key points without unnecessary detail. It was perfect! - Steve, Utah USA
Have you considered adding a gearbox, so that you could possibly have decent acceleration as well as maximum speed?
That would be awesome :D
Or you know..... you could make a pedal bike and not get lazy with a electric bike. Were all gonna become fat
Much more fun to just strap a 2 stroke engine to a bike and it makes a much cooler sound
@@harrisonsmetana2506 yesssss
i think modified gearbox of a bike using a drive shaft will be nice..just a imagination
Wow! Your problem solving skills are impressive and diverse! Well done!
I love how you casually speak about, I just redesigned this and built one of these as if it's simple. Your a very talented guy Tom.
I would love to see you making proper electric motocross bike in collaboration with colinfurze, you in charge of making battery and electronics and he making the frame.
Love a bit of Furze. I saw this and thought Colin could do something like this, then wondered if he had as I haven't watched all his videos yet!
that would be an amazing collab
Mira, yo tengo el motor central Aston Rider y lo vengo usando bastante bien. Lo he cambiado de mi rodado 16 plegable a mtb 26 y ahora en una 24. El kit lo cambia mi marido en unos instantes apretando un tornillo viene todo conectado y la pantalla tiene cargador de celular
u mean making the flame
colinfurze is an absolute douche and not to be taken seriously. He is aimed at a younger audience.
I actually like the sound of your belted setup vs. the hub motor. Gives it a bit of character.
dude this is amazing. i wish i had the tools and material to make something like that
I built a display similar to yours, which keeps track of amps and volts (watts) vs time, so the battery charge can be tracked. It also allows converting the controller from a speed control throttle to a watts controlled throttle, as you mentioned you did. I like that, it is more motorcycle like and you can then set preset power assist wattage amounts- speed might change but watts can stay at the preset level. My motor is a Bafang BBSHD with the internal controller.
Thank you for sharing all the details, including failures - so instructive!
What a great transition at 8:00 :D Awesome video as always!
xD
Superb job man!!!! A real pleasure to watch your vids!
Great project, i hope someday develope something like that. Thank's for share it !!
At 6:59 Tom said, “a lot has changed since then. Suddenly and seamlessly, I am seeing a fat wheel bicycle sliding sideways. The rider isn’t Tom. Took me a second to realize that KZhead had transitioned me to an ad for a bicycle.

This is everything YOU need to get up to speed on electrical bikes!
why do people like electric bikes? Im nolan and this is wheelhouse
Why did I read that in his voice?
I’m attempting to build a mountain bike wheelchair for my buddy... it’s a lot of math. I like the idea of an electronic motor to assist with the uphill and rough terrains. This was very informative and cheaper for me to watch your trial and errors lol. Thanks
Thanks for the EDUCATION on DIY e bike building. Got some ideas from your explainations!
Hey Tom, absolutly great video! That could be a start up for selling pre-installed parts ;-). Hopefully more to come, Greetings, Marc
Hi Tom, Really nice video recab of your learning curve during the build of your own ideal electric bike. I can imagine your feeling of gratification when you had reached your desired result after 3 years of work. It's not about having an electric bike, then you just buy one, its about knowing how everything works and creating your own optimal design. Pushing your own knowledge to get the most out of every mechanical and electrical detail for optimal results. People who even take time to create a video about there years of work and contribute by sharing their knowledge deserve at least a thumb up. Again, impressive piece of engineering Tom, thanks for sharing. Not one second of my time was wasted watching this video.
Yep. This is why I watch this video for the 11th time. There is no e-bike without some drawbacks I don't want. I'm investigating building a bike that can take cargo and possibly be charged with solar, that can be locked in a way that no one would like to put the effort into stealing it.
Thanks for this research, your work and your videos
Probably one of the most interesting KZhead channels out there
i did not seen this much passionate and dedicated person in my entire life..he never gives up..!
I have not seen? Or I did not see.
Thats because he is an engineer.
Tom, you're really gifted. You'll do well in life! Keep it up pall!
That is awesome! You have a bright future, Tom. Love your Videos
i think the next best idea for the new version would be to have a functional gearbox type arrangement, therefor you can have lots of torque down low but still a fast max speed. Whether is is through a servo that can mesh a gear to the belt, I would love to see how you would do it.
I think you are spot on with this video, as well as your assumptions on your audience. I’ve gasping at name brand electric bike prices and what you get for the money. Of course there is trial and error + hundreds of hours work involved in doing this DIY, but when it’s a hobby, all that matters is the enjoyment (and cost of parts). The idea that I can convert my existing bike to electric is tempting in so many ways, and your videos have shown that while it is a lot of work, it’s not black magic.
Check out the BBSHD series if you want something of a kit-form diy thing. I have the weaker, older bbs02 and it's a trooper. over 3k miles so far. i've seen people put 10k miles on them with only the sprocket wearing out. The HD versions are beefed up in every regard.
@@cho4d I'll check it out, thanks for the tip!
Yo I've seen your first build...it was inspiring....came across this video and WOW awesome! I got to see all up till now. Keep it up!
Thank you for what you are doing, and what you have found. I'm helpless, your know-how is impressive. I really only need to maintain 20M.P.H. on the side walk when I ride.
This video has given me a ton of inspiration and ideas. One of which being using the crank as the speed controller, either by using an encoder directly, or passing the crank through a back sprung differential with a potentiometer mounted to the differential bell. The latter would allow for you to use another pot on the handlebars to set the max amount of electric assist, and your additional pedal pressure while cycling normally would propel you forward electrically. This way you would still have to cycle for the sake of working out, but you would get additional range and some help up the steepest hills. This could motivate some to get on the bicycle seat more often.
How to make freewheel? Much needed for this project!
In my opinion your the tony stark of electric bikes. GOOD JOB! thanks for the brief tuts and inclusive data on mount designs and formulas.
I just starting seeing vid's w multiple motor's. Usually 775's and it seemed like there could be some problems there. Your application answered that!
Thanks for all this Data and Tips, might help someday with a similar project in Future
As an engineer this was very cool and inspiring, definitely worth subscribing. Keep up the good work young man and become a great inspiration for today's younger generation.
I wish I was as good as you at not only documenting my projects, but being able to summarize them in such a nice presentation. good work man, genuinely envious of your editing and build skills lmao
Awsome vid! Cant wait to see some more projects!
Thank you for this video..It was very useful and nice illustration about the whole things
This is amazing. You're really passionate and I wish you find sponsor to start up your own e-bike company.
What they've done isn't legal on UK roads. Fine for a KZhead video, not commercially viable.
Its because of too much power/speed or?
This guy is setting new goals for DIY projects!
Amazing work Tom! Thanks!
Really great design and innovative idea. I had the same idea but watching your video cleared a lot of my doubts and buy the way bicycle design is really nice. I will build myself one oneday👍👍👍

An engineer would consider the wasted energy converting electric to mechanical force.
Fascinating discussion and demonstration. By the way, Harley Davidson uses the two belt system, with the motor driving the tranny, and the second belt driving the rear wheel. I wonder if it's to make up for an underpowered motor.
Harley designed the 2 belt system to reduce sideways torque and its a lot quieter. A 1200cc Harley has 85 horsepower and up. The 125 cubic inch engine produces 130hp. Similar hp to a Toyota Prius. Custom engines can be 2.5 liter or 3 liter beasts. Also a large rear sprocket increases power too. For a 1000 pound bike they haul arse!

waaaaaaaaaat, 1M view in 4 days Tom!!!! ok simple, it is a cool video mate! watched it 2 times😉
Really good! I admire your tenacious, constantly changing/improving/refining your design - true development engineering. I don't know why you don't go on Dragons Den, patent all this, or work collaboratively with Dyson!
it's called Bafang Motor. Or from a series of BBSHD Mid Drives. He's trying to re invent the wheel. Motor at frame, small gear. motor on wheel, big gear.
Wonderful info. Thank you!
Great detailed vid. Thank you
Hi Tom Awesome Engineering skills, I was wondering what kind of CNC router you have? and how did you cut out most of the motor bracket profiles, did you make it yourself or purchase?, I am working on some modifications to e bike conversion myself and will need to make some brackets for support. Any info would be really appreciated. Thanks, are really talented and keep up the great inspiring work ! :)
Yes, I am an engineer, but only watch this kind of content when relaxing. Do plenty of engineering any other time... Thanks or your effort though!!
Great project well done.I have a home made (250 watt) Hub install, it goes well but unfortunately my forks are broke, I think the weighjt of the hub is a factor here.So, I will repair it eventually.I have also ordered a Murtisol 250 watt (14 inch Wheel) ebike, as I want to try a ready made off the shelf ebike, should arrive any day now and I can test it and write a review. Rob
Hope you never fall off at those speeds, great work.
You make some awesome engineering video's, keep up the good work!! :p I have a question about the motor kV - gear ratio. Were did you find that this ratio has to be a factor of 10? I am currently converting a minibike from petrol to electric, and i calculated this ratio for my build and it's around 16.9. I guess this will be really slugish then. Does this apply to all sizes of motors? Or is it just for the smaller ones?
14:00 is such a good feeling
Nice info. Tom. Keep going. 👏👍
Most original coolest thing I have seen in a long time sooo sooo cool
Hey, I love your videos Tom! Just saw a video of a guy making an ebike with a solar trailer, recovering power continually. Would be cool to see your take on something like this, not necessarily a bike or solar but a recharging manned vehicle. How far could you get from one full charge and whatever recharging you can achieve on route.

@@leviahamefula3994 Yes I think it was him
This dude could have just bought a nice electric motorcycle but looks like he had fun doing this
true but he did at home, what some companies spend 1000s on and hire a $100,000/yr engineer. Sure he spent more money than it would be to just buy a kit or an electric motorcycle but what he did is actually amazing, for just using Google and his own, non professional engineering mind.
Now, let's try it with a vespa, and a starter motor. ^_^
Plus electric motorcycles are pretty expensive already.
It's about chasing your dream
He did well!
Thanks so much for sharing. 😎👌🏼
For the filter on the motor there are hobby filters for RC cars. That material would work great
Damn, you’ve put in a lot of revisions!
Sometimes "engineering" is admitting that that thing you did was stupid and fixing it. Over and over and over again. Failure is always an option.
Amazing work! Your fabrication skills are impressive. How do you solder those large terminals on the batteries? It's always a disaster when I try.
He spot welds, check out a few videos showing the process. He doesn't solder them.
You 'can' solder them, but I don't recommend it. You would need a very hot soldering iron and a lot of patience.
If you want an affordable setup (relatively speaking to professional setups), look at the kWeld kit. They have various options just the bare essentials or also an added capacitor bank in case you don't have suitable batteries or whatever to power it from. It's still not cheap, one of the things that's pretty high on my wishlist for a few planned projects that involve more than 2-3 batteries (so far it has been low current/voltage stuff and I can get by with inserting batteries in standard plastic holders). For the occasional higher power stuff just taking a suitable lipo pack aimed at the remote controlled vehicle market can also work, as a bonus if you design them for that swapping batteries is fast and you get a standard connector to hook up to your charger out of the box. But when going for something large like a battery pack for an ebike I wouldn't want to go that route.
Awesome! Thanks for sharing.
Great work. I wish I was a student of Electrical Engineering one more time! 😃
