Ok so I finally got my motor yesterday, and I attempted to start the installation. It wasn't easy, I ended up only taking off the rear wheel and disassembling the axle because it has a peice of metal that attached the rear wheel to the frame that had to go inorder to put the sproket on. I don't know if this is a peice that has to be on the bike in order to work properly but I had no choice but to take it off. But the only problem is I cant get it off, I ended up unscrewing the bolts and finally got the greasy axle off but wasnt able to get the other bolt off so I can take that metal peice off. I ended working till midnight last night and only got as far as taking the wheel off, Im weak! Please help me what do I have to do to get this thing off?
