    I haven't seen where a sprocket is attached to a hub like a brake disc is on the left side. Seems like a great solution to the clam shell sprocket. Anyone have a link or site where there's pics of such setup? Is a disc brake hub beefy enough to handle the torque of the motor?

    sprockets are available that have both the usual 9 holes and also have an extra 6 holes that fit a disk brake mount (you need to remove the disk tho)

    i have heard of people having issues with mounting that way because of torque.

    yeah, those holes are really small - got one here but never tried it

    if I were to try, I think I'd drill out both the hub & sprocket to take larger bolts

    a better solution for a single speed bike is to just get a moped drum brake hub. puch and pugeot hubs are dirt cheap, have a sprocket on one side and provisions for a freewheel on the other, and even have good brakes already on them

    like my sprocket with both 6 & 9 holes already in it, that adapter depends on those 6 tiny brake disk bolts
