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.

WORKS

chainring size limit

The 44 and 45 tooth chainrings snagged on the dropouts so I needed to source a smaller one. To fit the one piece crank it needs a 24mm hole (well, the old chainring I measured had a 24mm hole anyhow). I obtained a 30T WeThePeople Supreme Sprocket from Winstanleys BMX: -

...aaaand it didn't fit!

So we got it on the lathe and milled out the centre until it fit the OPC!

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 - need to make a plate
