What size, outer diameter tires do you have? And can you fit larger? The reason I ask is that if you can fit larger tires this will have the affect of a larger chainring.When everything was tightened it was touching. I emailed California Ebikes and they recommended a 42T chainring so I ordered that. I think I will be happy.
The 42-T Bling Ring does not pull in the chain line as much as the 48. This is good because it is less likely to rub but you still may loose the lowest gear in the rear. That is okay also, because you will have plenty of power on tap.
