I've always wanted to make a circular frame out of alumnium tubing maybe like 1/2in or 3/4 in diameter. The shape would make for an easy drivetrain setup and would make it hard for people to push you. Done right it would also have pretty solid stability. We never have the time to protoype something like this and the resources aren't there to bend the tube that specific. We'd have to find someone or someplace who can. Another cool design is a octagon check out 180 Spam 2004. Finally I liked 67's 2005 chasis a horseshoe it was definitely a great concept. Just some thoughts.

Good luck,
Drew
