Rat Ebike
Hi Just finished my first home built ebike, the motor controller and throttle off a 2001 shopper, with some cutting grinding and filing of the hub so I could fit a 7 speed sprocket, then build a 26" wheel and get the wheel to fit an old frame I had in the shed, the controller had a little restrictor screw type joby fitted to it if you tune it the motor speeded up the other way it slowed down when i took it out altogether the speed of the motor increased at least 2 fold.

Took it out today with my Daughter on a wisper 905e which is good for 18mph with her 48kg weight, over took her at a guess I was doing close to 20mph not bad four a bike that cost less than 60 pounds to build (not including the battery) which came off my heinzmann mtb.
