Post subject:  Pinion gear vs. motor vs. top speed

Hello,

just in case that any more are interestet in which component(s) to pick for a designated top speed, I would like to post a simplified formula below.


pinion gear = spur gear * internal ratio * 5050 * designated top speed / motor rpm / 60


- 5050 is specific for 63mm tyres
- Top speed is needed in km/h


Please don't forget to check the 'fastest' allowed gear ratio for the used motor.
Just ask if you want to have the detailed formula or a formula for mph and/or other tyre diameters.
