Re: Ok, I give up. How do you start these things?!
Yes, by running a larger rear sprocket.
Larger sprocket = more torque and slower top speed.
I have a 40 tooth on mine and I am impressed by the hill climbing torque it has although I do have to pedal assist it. It will not climb up the hill all on it's own.
