Hi John

So the rubber coating is a waste of time ? I'll defer to your greater experience here and try some fine grip tape
I took the bike out for a quick spin after work . I tightened the spring right up until the motor was constantly touching the tyre and it worked 80 % of the time
. There was a little drag from the motor but it wasn't an issue. I had strived to set this up so it was the initial kick from the motor that initiated contact with the tyre.It would seem that this initial kick isn't sufficient on this size of motor ? Is there a way to increase the initial startup input to overcome this ?
On another point,and I don't know if it's specific to my bike geometry,but I find I cannot remove the rear wheel with the drive in place.Obviously, I can just undo the 3 bolts to rotate the drive out of the way, but they would then need set up again. Could be an issue should I puncture.
I shoudn't imagine I'll need an extension bracket as it's probably the opposite that's required on this bike (Cannondale caad 10). Is ther an ideal setup ? ie should the axle and pivots points of the bracket line up to the rear wheel axle ?
I'll await your diagnosis if the video works
Thanks for all the help and advice!
