I'm looking at buying a used eBike. It has a Tongsheng 500w motor installed already. I'm told that not all Tongsheng setups can use a throttle. Is there some way to tell if this particular Tongsheng can do it?
It is not the motor but the controller that the throttle hooks up to, you would need to know what kind of controller it has and the controller could always be changed to one that does accept a throttle.
