Hackspace BMX

I'm in the process of building a BMX for the Hackspace from various donated parts. We had a Mongoose frame, forks, stem, bars, one-piece crank, chainring, levers, most of an Oddessy Gyro, but lacking wheels and tyres. I was lucky enough to find a bunch of parts on ebay including wheels and tyres and after some negotiation I was able to swap them for an old-style XBox (of which I had a spare) instead of cash (which is never spare!) It turns out that these newly obtained parts are an almost complete bike too! And quite decent components as well.

TODO

chainring size limit

The 44 and 45 tooth chainrings snag on the dropouts so we need a smaller one - perhaps 30T

To fit the one piece crank it needs a 24mm hole (well, the old chainring I measured had a 24mm hole anyhow)

Gyro & Potts Mod

The stem we have is a fangled fork-top thing and has no hollow stem bolt.

I don't know how to mount a gyro on this thing!
