Hello.
Im new to this forum.
I have a intrest in EV cars and looking to do a budget build.

But firstly doesn anyone know of in in wheel hub electric motors?
I recent read a article about a university that converted a frwd car to awd and had two in hub motors in the rear tires. Supposedley only costing $3000. $3000 sounds very low for this type of build but i was intrested in the in wheel motors.

Anyone know where to start looking for one?

Or maybe even a motor that would connect to the drive shaft of a rwd.

Im intrested in keeping the engine in place and having some type of hybrid build.

Has anyone done this successfully?

Any belp would be appreciated.

They don't exist (in a practical sense), or work for anything much larger than a bicycle.

Bad idea.

Lack of gearing means you need big heavy motor, which means big heavy hub and high unsprung weight.

Big heavy motor needs cooling, how is that dealt with?

Ditto brakes, regenerative braking is not enough, where do you put the brakes?
