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
