I just bought myself a bike and noticed that the bottom bracket was wobbling quite a bit. The whole assembly is wobbling actually. Watch this video:
I'd like to avoid changing stuff like bearings etc. I don't know much about bikes but I'm quite handy with cars so hopefully it shouldn't be too big of a challenge to fix this.
The bike itself isn't worth much. I bought it to get myself to and from work, and I'd like to do it safely without ending up on the floor.
What I did notice (don't know if it makes any difference) is the huge gap between the crank and the frame on the non-chain side.
