I'm building a freewheel crank.
Where are the cheapest places to buy the sprockets, I am looking for 50T on up.
Also, how does one calculate, or know, what kind of speed and torque I would have when changing the motor sprocket and the crank sprocket.
I have 2 motors, one is grossly overpowered, 3000W nominal motor, the other motor is a 1500W nominal motor.
I am building a mid-motor ebike, for hill and stair climbing.
