Thanks for the responses.

The7, I'm not familiar with different hub motors. I've read that BionX uses a freewheel, but other than that, I'm ignorant.

Lowell, There is a dealer with demo bikes about 400 miles south, Electric Cyclery in Laguna Beach, CA (http://www.electriccyclery.com/catalog/). I would like to get down there but haven't found the time. I searched Crystlalyte Kits on the net, bit I can't find any with Li power packs. Is this a mix and match thing that I would do myself?

Thanks,
Tom
