My good old ( was free ) trusty Schiwe is broken and I can't fix it, I got a $220 quote for fixing it. So I think the $ is better off putting toward a new one.
The thing is I have idea about bikes … what should I look for ?
I found an old topic about Road bike sizing advice, how do you even measure the frame ? I'm 168cm tall.
Here are a few bikes I found on gumtree.
Avanti
16 speed Giant
Avanti Pista
Merida Juliet Road 904
EDIT: Don't worry about the sizing, as I only use the bike as to get me from A to B.
If I were you I would buy a new Cell or Reid bike.
They're decent enough, have free servicing, and if you buy in store you will get one thats fit you properly, which is important regardless of how much you're riding.
