I put an e-bike kit on my daily commuter because of the wind, and I am glad I did. However, my recumbent is my summer, recreational, bike. As such I do not have an assist motor on it.

I have had mopeds and motorcycles. They are significantly different in bike feel and operation from my e-bike.

I am in the process of building a solar electric e-trike. However, it is on hold. As a teacher I am going to have my robotics club doing a lot of it (the principal is all for it as a technology/engineering project). As such, the panels are in a box along with the charge controller. It is next years project.
