Hello! I have been researching parts for a while and I cant wait to start building. I will be purchasing an Enertion R - SPEC motor and Enertion's motor mount. I will also be purchasing the ADS 32T Kegel Hub Driver. I'm not sure about what type of belt to buy and what pulley I should buy to go on the motor. Any help about a belt size or pulley size would be appreciated. Thanks!
