Dig that Swingbike. I want to build one.
I ridden 2 of them.
The 1st was Locojoe's, he built it, 20" stingray based, I think . He had it at the the 1st Midwest Bicycle Fest. After trying for about 10ft, I new I was going to kill myself and quit, later I was riding the path with a kid,13-14, friend of randys who could ride that swingbike, and seeing how he rode (steer with your body moreso than your arms), I tried again, and rode all the way around the park. wow. fun and challenging.
The other swingbike was factory made 26", owned by one of the Coasters, just get on and ride, it was eazy, different geometry .
Going to build one.
Looks like you got it going.
My thought,,,,, Bend a seatpost to set back a little more and give yourself even more leg clearance to get it crossedup. I also wonder what it would be like to turn the frame around, the hump may give more leg room. Compare the way it rides with the frame both ways.
Loooks like a cool project, keep us in formed. Dangerous Dan
