Relatively Simple Rear Wheel Issue
Hey guys, I just dove into fixing up an old bike about a week ago. I'm new to cycling and probably wouldn't have this question otherwise, so I figure someone here will know what's wrong:
I'm trying to put the rear wheel back onto the bike after replacing the tire tubes. It's not a quick-release, it's just two slots that the axel has to slide into. Here's a picture:
First problem is that the axel has to practically be beat into the slots because they're super-tight. Barely big enough for the axel. Don't know if that's normal, but I'm using the same wheels that came with the frame. Second, axel is in the slots I'm not sure exactly how to align it right. Third, and MOST importantly... How can I make sure it stays on? Last night I got the wheel on, tightened the bolts, and went outside to try it out, and the force of the chain alone pulling on the wheel's cogs pulled it right off the frame. I really feel like I'm missing something here. Either a step I'm not taking or a part I'm not using... Because it's clearly not safe the way I'm doing it. Anyone care to advise? Thanks in advance!
