I am planning to build an e-bike and I realized that a car starter motor would be a good motor, as it has enough power (1kW, enough for my bike) and the voltage is practical enough. Will it handle the stress?
A mechanic told me that the coil in it would be destroyed after 30 seconds, as it isn't meant to be used a lot. I am only interested in the motor, not the solenoid. I will be using it at 75% of its power, at most, so not too much stress. Will it work? It's going to replace a 50cc motor of a piaggio ciao.
