I have a brand new bike and I am installing a Skyhawk motor.
I installed the rear sprocket using a pineapple hub. I am not sure how this could have tightened anything unless it happened while reinstalling onto the bike, maybe overtightened one of the nuts or something.
In any case, what can I try before having to save and then spend another $40.00 to get to the bike shop and back? I am on a pension and it took me almost 2 years to save enough money to buy this stuff. Can anyone help?
