[trikes] hubless wheel trike

[Colin Bryant]

Certainly, you couldn't ride on anything but a hard surface, with their prototype and not above 2.4mph but they are a bunch of engineering students, not trike riders.  The trike has a ton of other problems too (no sweep back of cross member, right brake exposed etc.).

I can see using rim mounted ring style disk brakes, like some Honda motorcycles in the 80's, to deal with brakes.  Perhaps a shaft drive, with a pinion gear working on the enclosed edge of the wheel.

The chain out at the rim thing looks troublesome.

I've seen sketches of bicycles and motorcycles, with hubless wheels, for years, but it always seemed to be a solution, looking for a problem.  Given the high side loads on trike hubs and spokes, this could actually be a solution, to a problem.
