I am so dissapointed....I just got my motor kit and had my cruiser bicycle ready to except it...so I thought. As I was following the steps and getting ready to mount my sprocket I find that it won't fit over the coaster brake arm. So clever me decides to loosen the nut over the coaster brake arm so I can pull the arm off. In doing so I pulled the whole bolt contraption out and falling to the ground was bearings and maybe something else but I couldnt find anything. Now that I have put it back together the wheel doesn't spinn right. Should I take the wheel to a bike repair shop and maybe they can fix it or do I need to buy a brand new rear wheel? I am so pissed at myself!
