Bike Hack – How to Build an Electric Bike! (or Trike Is it?)
I have to say that although I’ve seen slew of electric bikes on the market these days, this homemade electric trike is probably the one I would want to get or build at the least.
Check out the video, this thing ROCKS:

It looks pretty simple enough to build as you can see above with 2 batteries, fuse, switches, bunch of wires, and what looks like a control unit of some sort for the motors.
Here’s the parts list:
This part of the project was a strange mixture of quality and last minute bodging.
- I used two 12v 32amp batteries
- A 75amp 24V speed controller made by 4QD in England- quite pricey but really reliable
- 5 LED battery condition meter
- Plunger pot for throttle
- Lots of cable
- Connectors for batteries
- Two 24v 300W DC motors
