Well I had a few spare hours tonight and finished up the frame. Got some nice night time snowy pics. It turned out well. http://www.viragotech.com/junk/pedalpower.html Maybe I can add a side car and paint it yellow??? seriously though, a bike with a side car? Make it pedal like the two person pond boat.
Finally took it for a long ride and the right side crank bearing fell apart. Had to fish them out of the frame as they traveled around. Still one in the frame that won't come out. Gear ratio was way high. I was pedaling like mad, not get very far. originaly was a 52/48 to 36/16 its now a 29/36 to 48/16 I figure about 1.24:3 much better only snag is the middle sprocket in the 3 gear set can't be used so the chain can clear.
Shifter Now all you need is one of those three handle "Lightnin' Rod" shifters from an 83-84 Hurst Olds to shift those sprockets. I modified the thumb shifter on my 3 speed English racer many, many years ago by mounting it on the crossbar and attaching a gear shift lever and knob from an old Ford to it. Looked great and worked (for a while). I always thought it would be neat to take two identical bikes and weld up a cage between them and make a paddle boat type contraption. But then, I'd probably end up putting a motor on it and killing myself. I totalled out 2 bikes as a kid. One slid into a stop sign and the other slid into a gas pump. Going down in limestone really hurts.
Re: Shifter There is no shifting going on with them sprockts. Its a set system. I got a 0.80:3 ratio But I may find a granny bike with a 3 speed plantary internal hub. That will add some gears real easy. Thought I'm sure it will have to be a custome build to lace it into a 20in rim.
