Hello everyone, I am a student from Taiwan and I am wondering:
1.How to convert the wheel speed(rad/s or RPM) to the e-bike(two wheel drive) speed(m/s or km/hr)?
2.Is there any formula or equation that can represent the relationship between wheel speed(rad/s or RPM) and e-bike(two wheel drive) speed(m/s or km/hr)?
3.I had saw a formula : v=(n*60*L)/1000 where v is e-bike speed, n is wheel's rpm and L is the perimeter of the wheel. Can this formula used for two wheel drive e-bike?

PS:Assume that two wheel's speed are synchronous.
thanks for your answer!!
