Jules said:I am making an electric bicycle using a Sinclair 12 volt motor, gearbox and 12 volt battery. I have found several PWM speed controllers around, but none to control the high currents involved. Has anyone a schematic or helpful link ? Thanks

(60 amps? or so) Because of this, and/or the possibility of Mos-Fet Failure, A fuseable link is highly recommended and it can be easily made using a 1 inch long piece of a smaller copper wire, (maybe a 20 AWG) inserted into the Anode lead coming from the battery positive.
