Impossible Wheel

Building an impossible wheel is quite impossible.

However, the hangers for a BC Wheel could be made from old
crank arms with a bit of pipe 3/8" inside diameter and 5/8"
outside diameter, and big flat washers to secure the crank
arms tightly to the bicycle wheel axle (3/8" diameter). Next
simply add wide pedals.

Using cottered cranks also allows the possibility of cutting
flats into the pipe for the use of cotter pins which could
be used to hold the cranks to the axle even tighter.

Going further, pipe with a smaller inside diameter could be
used and threads could be tapped inside them so the pipe
would actually screw onto the axle ends for an even more
secure fit. Lock nuts on the axle ends could thus be avoided
and be one less odd bit of metal sticking out.
