I ordered a friction roller drive kit from www.bikemotorparts.com/ today. They're also called Formula Bike Engines. I plan on putting it on my yellow bike (see picture gallery) or the Cranbrook Huffy.
Question to the roller drive users: How long have you traveled in one trip with this type of drive? Do you have to stop to let the tire cool, or is that a non-issue?
