Thanks for the reply 2Old,
During the four years that you have had your ebikes:
How often do you ride each one?
How far would you say you ride on a weekly basis?
Do you ride up a lot of steep hills?
Do you ride in the winter, with below freezing temperatures?
How fast can your bikes take you?
And what motors do you have? Make and model?
currently I'm doing a minimum of 26 miles per day without a motor, 7 days a week. with some steep hills on my commute.
