Building an Electric Bike

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...

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!

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.

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.

[@olivertrevellyan9789]

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.

[@jhsevs]

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.

[@robmac3702]

Agree with this comment completely. Please say that these are private roads otherwise what you are doing is illegal. Also, as this is a new kit, a throttle is also illegal. I do like how you are designing new ways for an electric bike but maybe look at being more efficient by powering the crank rather than just the rear wheel. There are kits out there for a crank with a freewheel in them so when powering the crank, the crank arms wont spin.

it's very rarely my "DAD" will be glued to any video i show him on You-Tube... i recently bought an E-bike! and it was absolutely the best money iv ever spent in my life."EVER" I'd recommend one to anyone. but my god... 'TOM MY MAN" THAT WAS AWESOME & LORD COULD IT MOVE.. : ) when i think of my 30kg bike with its 20inch wheels running out of battery, & im still 5 miles away from home.. it make's me want one like that. IV SAW LOAD'S OF 'MAKE YOUR OWN EBIKE VIDEOS BUT... THIS WIN'S : ) HANDS DOWN.... PURE CLASS! : )

[@friendlynomad9840]

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.

[@kettlefuryyt]

He spot welds, check out a few videos showing the process. He doesn't solder them.

[@RingingResonance]

You 'can' solder them, but I don't recommend it. You would need a very hot soldering iron and a lot of patience.

[@extrastuff9463]

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.

Seen this before, loved watching it from the start again. Amazing the work that you've done and with a 3d printer

@@thecube5861 Yes, but unless you are "name greedy corporation like apple" your design should have longest possible utility life, of course balanced between quality, what it is designed to do, price and such factors.

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 !
