I took the back wheel off from the bike itself so that I could take out the old innertubes and replace them with new ones. That I did, but in doing that had to take the chain off the bits at the back but I don't know how to put the whole thing back together again. The geary bit is still on and there is still a chain through it.
God I just wish I had one of those old bikes without all this - much simpler as it just goes round one thing!
