I had the idea for a fixed gear tallbike about 3 years ago. Not an original idea, I'm sure someone had done it, but this was when the "fixie" thing was first starting to really blow up, and I felt it necessary to poke some fun at it. Also the Drop Out Bicycle Club, of which I am a member was invited to have a booth at the first Oregon Handmade Bike Show. I was a bit dumbfounded when we were approached, as it was entirely professional builders, of which I have the most admiration and respect. I knew I had to do something special. I had Mizutani Seraph that I got at Goodwill and a Bridgestone Kabuki from a yard sale, so I had two lugged mild steel frames from which to build a tallbike. I always start with the steerer tube, and I set it up to both the top and bottom headsets, so the tube in between is more of a stem extension. Four bearings are sturdier than two, and once the neck extension is fabricated it acts as a jig, holding the top frame in place. I also did a monostay, and placed a substantial gusset at the bottom bracket. It also got track ends that line up with the bottom bracket for maximum chain adjustment. I finished it off with a big 52 tooth chainring. The most recent addtion is the bum bars, which a very comfortable. So here it is, the Suicycle.
Brakeless? Check. No foot retention? Check. No lockring? Check. (welded 5sp. cluster)
27" rear wheel & 26" front wheel (for teh barspinz)
Here you can see the sprocket gusset, and triangle gusset
The rather precarious monostay, made from part of a fork leg.
Seat lug with seat stays carefully cut away, cut and laced Brooks saddle.
Rear dropout cut from a Schwinn Varsity and grafted to what was a vertical dropout.
