Dave Tass' SWB

Dave Tass built this clever SWB from a junked bike and muffler pipe. It's a bit of a prototype, as he wants to make several for friends and family. Unlike the typical TE clone, using joints from an existing frame didn't force any unpleasant compromises that would affect ergonomics or handling.

Dave used crossover drive, like a tandem or most of Dave Krafft's bikes. This means the front cranks get swapped, leaving the pedal threads reversed. So he drilled and tapped new holes to get correct threading, and shorten the cranks to 155mm.

Seatpost from an upright bike does double duty. A section of tubing welded to the front supports the backrest, and the old seat clamp holds aluminum rods that support the fender.
