The first ever custom fabricated bunyip bike, the {unnamed bike} is getting closer to completion! The front triangle is now all mitred, the dropouts are spaced correctly and things are nicely aligned.
Since this is a new blog and there's been plenty of work before this started, I'll explain it's genesis.
The geometry is based on 9 months of playing polo on my current bike, "Lil' Sensenmann". Sensenmann was an exercise in making a short wheelbase 26" bike from readily available parts. Namely, an old 'waterpipe' juvenile road bike (to fit 24" wheelchair wheels), a nice Raleigh cromo MTB fork and a few bits brazed on for frame strength and braking performance.
The new bike as a few tweaks: The main change is to the steering, with a sensible headtube angle and a more respectable amount of trail. There's more BB drop to get closer to the ball and bring the seat down in relation to the handlebar. The chainstays are shorter (with track-ends so the wheel can still be installed). The seat tube is still very relaxed to put the seat back over the rear axle. Turns out the front centre on Sensenmann is just long enough that I don't have issues with toe overlap despite appearing too short.
