Hey @hi ,

A 500 Watt motor will probably provide a max speed of 20 mph for an electric bike. See: https://www.sixthreezero.com/blogs/bike-advice/whats-the-difference-between-a-250w-and-a-500w-motor-electric-bicycle

Hope that helps.

@hi Yes you could use rotational mechanics but this is a topic commonly taught in Year 13.

However, if you send a link of the wheel that you are looking to purchase, I could write up a blog post on how to calculate it as I am sure it could help many people who are looking into rotational mechanics?
