The energy is returning slowly. I did get the drive completed yesterday. It appears to work satisfactorily. With the small 6" wheel, it will fit one most any bike I think. By keeping it down to 24v the need for complicated electronics is pretty much eliminated. Even so it is still pretty darn effective.

I have lots of tests to run on the bike for a while but this one is much simpler than my big bike. I have high hopes for it, which is usually the kiss of death for a device I build. We shall see.
