Technically, this isn't the first bicycle I made. It is, however the first bicycle that A. I made completely on my own, and B. is completely rideable. So, it get's the official "No. 1" stamp. We won't count the class bikes and screw-ups.
There's certainly something about one's first. I still ride this bike nearly every day, to and fro. I'll never get rid of it. It is comfortable and fuss-free—a 650B x 42mm porteur-style commuter that goes wherever I point. It is bronze fillet-brazed, made from (mostly) True Temper OX Platinum tubing, and features a wet-paint finish. The parts are largely US-made: Paul Components brakes; Chris King headset; Phil Wood hubs and bottom bracket; Velocity rims; and White Industries cranks.
