An interesting Potato.

This guy makes some really interesting frames, wheels, etc.

I like his take on the Aerospoke.

thats pretty rad
would take a sh!tload of work

No chain is the new no brakes

I like his other take on the spok. A home made version where he welds 5 lengths of pipe between hub and rim. Then removes all the spokes. theres a thread about it on some finnish bike forum. weighs in at about 2kg
