I've had a few questions about the pedals. They do not move. They are basically footpegs. The crank arms are attached to a fixed shaft. The driven pulley and driver sprocket are brazed together and float on the fixed shaft on two bearings.

If you notice my inspiration for this is from Mike Krumpe's The New Frontier.


I just had the bike out for the first time tonight. No real bug's at all.

Thank you Mike for taking the time to explain the choices you made in your bike.

Cheers, Perry
