What do you think about using a car starter motor on a bike ?
I've build a motorized bike with a old Lawn-boy 2cycle engine, it work well and do 27 miles/liter of fuel.
With the gas engine, I was able to go up to 53 mph but now I want to convert it to electric power.
I have a Bosch starter motor form a jetta diesel with permanent magnets and internal gear reduction.
This motor turn around 6000 rpm at 12v and draw something like 40 amps at no-load.
On my bike the motor won't be able to turn faster than 3000 - 3500 rpm and will be controlled with a homebuild pwm controller.
I have some doubts about the efficiency of this motor on my setup.
