I was supposed to be hauling off some of the scrap bikes and tubing I've got stashed around but while digging through my scrap tubing box I got sidetracked and instead built another swing bike. I don't need another swing bike. I guess when I found the 2 head/down tubes from the girls bikes I couldn't resist. Used the rear triangle off of the tandem MTB I made years ago.

This is an eccentric/offset wheeled bike. The wheels are 16" rims welded inside of 20" rims. The frame is a Stingray which I removed the fender bracket between the 2 rear stays to make room for the tire when in it's longest position. I replaced the front fork with a 26" fork to give clearance for the tire. Put on a really short crank, seat and bars from the parts bin.

Finally got the rear eccentric wheel finished and put a bike together using the wheels. The wheels are 16" rims welded inside of 20" rims. The frame is a Stingray which I removed the fender bracket between the 2 rear stays to make room for the tire when in it's longest position. I replaced the front fork with a 26" fork to give clearance for the tire. Put on a really short crank, seat and bars from the parts bin.

My lazy man version of an eccentric wheel. It's a 16" rim inside a 20". The ride was kinda cool. Now to do a back one.

This swing bike was made from two 26" girls frames. A Schwinn and a Raleigh. Added a banana seat and ape hangers and gave to a neighbor kid.
