Hey, Jeep, or should I call you PorscheDude?
I've d/l'd the plans for making a minibike out of bicycle parts that someone had listed here. Luckily for me, there's a recycled bike shop nearby with just about every kind of part or frame that I could ever need or want, including some VERY hard to find parts. Not only do these guys repair and build bikes, they also use old junked bicycles as the base for bicycle artwork - forks and rims welded together to make a framework for garbage cans, cranks and gears used for flowers, and there's a 10' tall 3-D cactus made out of flattened-out ten-speed rims to create the "ribs" and smaller rims for the shape.
Oops, somewhat off-topic, I suppose ... Okay, back on topic. Bicycle frames fora new minibike. Does anyone else have any other suggestions?
