Good day,
does anybody tried to use bicycle fixed gear hub for mid drive system?
If yes, what power you pushed through it (un)successfully? What brand of hub did you use? Hub in pic is just random fixed gear (sealed bearing) hub from internet.
BTW, FYI:
Fixed gear hub which has fixed sprocket threaded with lock ring. It has threads on both sides for hub, - 34mm for sprocket and 29mm for lock ring/nut. Some of these hubs have 34mm&29mm threads on both sides, so you can screw on one side sprocket, and on another disk rotor (via 34mm adapter to 6 bolts). So the question is if these hubs do work for mid drive systems.
If you would ask why fixed gear hub instead regular rear hub... - because fixed hub has lock ring which does not allow unscrew sprocket when motor is cogging (when you don't use freewheel or one way bearing).
Sure there are two sides / two side flanged bicycles 6 bolts (each side has option to screw disk rotor or sprocket via 34mm adapter) hubs which are perfect for mid drive appliacation but these fixed gear hubs are accesable too.
You could point to a topic where somebody is experimented with fixed gear hubs on mid drive system.
