I was looking for a bicycle online for Carol. Some rat bat turd stole her bike right out of her garage in broad day light. I ran across thatsdax's web site. I was in love, enthroled and addicted at first site! 15 or so builds later and man! Love em even more.
So far I have learned small engine repair. Bicycle repair and maintenance. Complex math to create reduction gears. To machine parts with out complex tools or skills. But mostly, motorized bicycles gave me you guys. You all ain't all that fun to look at, but a blast to know.
(and I wonder why I get so many hate PMs, snork)
