#1353: Hingebike

I’m always impressed by people who make working technology using junk.

Today’s invention is a bikeframe that can be built using a few planks and a hinge or two.

Three wooden triangles (blue and grey) made of planks, or whatever else is lying around, are bolted together and hinged where they meet (blue/grey interface).

You get some odd handling but your cerebellum will solve the dynamics problem quickly and your wallet will appreciate not having paid out £2k for the latest highly-stealable, magnesium/duralumin, hand forged sculpture from Cremola or whoever.
