when i want to stop pedalling i usually just stop pedalling
That’s a solution in search of a problem.
It looks cool, but its too heavy, you’re stuffed if you lose the chain, and (critically) it only brakes the back wheel. If you’re only going to run one brake, then … yada, yada,
also prob your pads would get fouled due to grease…
maybe if they ran a disc on the non drive side crank… or maybe just the rear hub
Still, its pretty funny / nerdy / retarded.
