Human powered bikes used to be my passion.
The bike I'll never forget was a humble Schwinn. It was based on the frame Schwinn used for Mountain Bike racing in 1995 with slightly less aggressive hardware and no suspension at all. I put thousands of miles on that bike; it was my main transportation through college and the first half of grad school, and my main source of recreation. One of those bikes that felt so comfortable it was like an extension of my body and I could feel every tube flex and knew the uniqueness of ever tooth in the gearset.
Shortly after being married it was stolen from me. I took it as kind of a compliment actually. In an upscale neighborhood in St Louis where people rode around on $1500 European bikes with the latest hardware, someone went to the effort of breaking the bricks in my carport to free the anchors that were cable locked to my bike. At least the thief had an eye for quality.
Not having any money and not being satisfied with a cheap bike, I decided it was time to try my hand at building. Buying parts on e-bay and wherever I could find them, I managed to assemble what I think is a pretty sweet urban assault bike. It's an aluminum Canondale frame from the mid-90s. I couldn't afford an XTR derailleur so I bought junk ones and rebuilt them into a working unit, added a light crankset, rigid Bridgestone fork, SRAM shifters, wide semi-slicks, and assorted other hardware. I also picked up a pair of wheels with twisted spokes that just look cool, but are a bitch to keep true.
The end result cost me under $200 and absolutely rips through Urban traffic while handling shortcuts off-road and through parks easily.
It was my first experience assembling a vehicle from scratch and gave me the confidence to start building a motorcycle. Surprisingly it's never been as special to me as my store-bought Schwinn, but it does the trick. I still have dreams of adding an oversized chainring with a third "overdrive" shifter for those times I'm riding with traffic and need to get up in the 30mph range for long runs. At this point though, the motorized projects seem to have taken precedence. Someday...
I'll have to get a better picture, but this one at least gives an idea.
