For XC and roadies in Hobart, it gets even better...
We have a group that rides at lunchtime everyday from somewhere in the CBD. The ability to ride from the capital and be in the bush on any number of XC trails (and the possibilities are almost endless) or be on any number of great roads on the roadie is unmatched. Mt Wellington hanging over the city really is an asset for DH, XC and roadies alike. I still find it hard to believe that I am so lucky to be able to go bush at lunchtime every single day of the week, on different trails all the time, from the centre of the city!
Our group have so many XC and road circuits in our arsenal that fit into a lunch break at work it is almost too good to be true!
The weather (contrary to popular belief) is pretty temperate all year round and rarely is the weather bad enough to cancel a ride.
Weekends and outside working hours is a whole other world of opportunities (as mentioned by others) with things such as Glenorchy and Clarence MTB parks, endless bush trails, more single trails than you could poke a stick at, fire trails criss crossing the state and awesome ride locations everywhere within 2 hours driving distance (usually a lot less than 2 hours). So many 50 to 100km scenic road ride circuits, the mouth waters!
Events: XC, enduro and multisport events galore! DH and 4X too. If you're into track, road, crit, audax, then there's all that too. Even MTB orienteering if that's your thing.
I love the bush (bushwalking is massive down here)... just getting carried away now, better stop
Spend a few weeks riding with some locals and you will not be disappointed
