I’m very late picking up this thread, but thought I’d throw some info in, Pigface.
WonnyJ is pretty much spot on – head towards the west of the city to live. I’d personally avoid Mumbles like the plague – full of tourists and daytrippers whenever the sun comes out, with only one main road in and out!
There are loads, and I mean LOADS of bike routes around the edge of the city. My work has has just moved to the north of the city and I’ve found miles of bike paths that I had no idea about. I barely have to touch a road in my 4 mile commute.
There is also plenty of very technical riding within a few miles of the city centre. WonnyJ mentioned Kilvey – my most local trails. It’s like a mini trail centre with added GNARRR (if you’ll excuse me 😳 ) and minus the numpty crowds. Normally! Add in riding in Clyne, Gower, up in the mountains, easy access to quite a few trails centres, and you have to ask why Swansea isn’t marketed as the base for MTBing in S Wales?
The city centre isn’t great but it has just enough to be able to call itself a ‘city’.

We’ll show you the trails and have a weekly thursday night ride and pint. There is normally someone riding somewhere during the week.
