Q100cst rear hub motor and disc brakes question

[bmc]

Has anyone fitted this motor to a disk brake frame ? I tried mine in a frame with inboard post mounts, and the rotor fouled the mount. I'm just wondering if it'll fit on an outboard post or IS mounting ?

Love to hear from anyone who has done this, regarding rotor size etc.

You need a washer or two on the axle. Whenever you fit a rear motor with a disc brake, your first task should be to set the spacing on the disc side so that the disc lines up with the caliper. When you have that right, you sort out the spacing on the other side to keep the sprocket and chain off the frame.
