I recently got a rebranded onebot s6, sold under the commercial name ocean drive ora. AFAIK it's all the same except for the fact that there is no throttle grip. Since the bike has no mechanical gears, and i live in a hilly area, moving uphill without a throttle is a pain. Does anyone know where can I get a compatible throttle grip and it there's anything else to it than just hooking it up to the motor controller and running the wires? thank you..
