My neighbor had an electric bicycle he got in a trade a while back. It's a brushed Aotema front hub motor, with two 12v10AH batteries in the back. The controller has nothing but chinese on it, and it says "24v". It's extremely slow, it can't go up any grade of hill without pedal support and it maintains probably 8 mph on a flat. One battery shows 13.2v right after a charge, the other shows 13.0v. When I connect the battery directly to the motor, it turns the same speed noload as when I run it through the controller at wide open throttle. The battery sack has room for a third battery, but is currently filled with white packing foam!
The goal is to have something I can commute with that maintains 20-25 mph on flats and be able to tackle medium hills at about 10 mph. (This isn't San Fransisco!)
Any thoughts on what my next step should be? Should I scrap this thing and start from scratch, or is the performance available from this kit? Can I go 36v? Can I go 48v?
