As you'll see from a previous post, i have a Proflex Animal I'm going to convert. My left leg is mostly paralysed which is why i want an eBike for exercise. I have used the front hub 8Fun kit, but it wont fit the Girvin forks. That to me meant rear hub motor, as i need the thumb throttle to get going in some situations. I read a review of the 8Fun mid drive kit and it had a thumb throttle?? So is the chain ring separate to the pedal arms on a mid drive kit then? As obviously the front chain ring needs to turn under throttle, but does that spin the pedals or not??
