my brother built a bike using a voilamart 250w 36v kit a while back and the controller packed in. so he got what looks like a brain power contoller with a 4button lcd controller. now its wired up and if i lift the wheel and press the on button the wheel spins for a couple of seconds then stops. so i presume we are nearly there with the wiring etc...the main problem we have is there are no setting instructions with the lcd unit..or parimitor settings . as ive never set one of these before all info would be greatly appreciated
