Yeah. I've dusted it off, straightened the handlebars and put the pedals back on.
Unfortunately, in storage it's bent it's rear mech. So time to upgrade!
This year I have to get out on the bike. I live in the perfect place for it really, I've got a BMX track in the park next door, I'm 10 minutes ride away from urban riding and 10 minutes drive away from the peak district.
If you're looking at buying a bike now, you've missed most of the good sales. It's the start of the season and most bike shops are now in full swing selling 2011 bikes.
Something like on of these :

Realistically, anything that's cheaper than that will look like a bike, but won't ride like one.
