Me too! Honestly the real problem for singles and clunky twins is the uneven power output causing a push/pull effect on the rear wheel. My issue is only under hard power as the belt on the primary reduction dampens the motor's compression strokes from the drive train and rear wheel during cruising. Secondary reduction is chain only. I might mount a sprocket carrier directly to the hub with as large a bolt pattern as I can and just remember "thrust is not the goal."
