We've had a hellish summer here on the west half of the united states.. it's been hot, dry, polluted, and everything's been on fire. Riding a bike has been the last thing on my mind for months.. finally it's looking like we're in the clear.
There is a nut on the freewheel side that made my YTW-06 about 142mm wide or so. Take the nut off, and the motor is 135mm wide but a 7 speed freewheel extrudes past the axle and contacts the frame..
And the axle has almost nothing for a shoulder, so forget just throwing a washer on there..
I have an aluminum road bike frame here, so i sure as hell am not going to stretch the drops far..
So being that the nut is maybe.. 8mm? i hit it with an angle grinder and hand file and took almost half the width off the nut.
Now i only need to bend my frame about 3-4mm or so to fit the dropout in.
It's off to get spoked and i'll have some feedback on it's power at low levels soonish.
