I live about 2 miles away from my office and the other day i found this little gem.
I've dubbed it the Hipster Speical.
Generic hipster bike, but nearly everything on its been upgraded, cranks, pedals, bars, seat, etc.
I got it for $80, and put another $80 into it for new bearings, tires, a tune up at the local shop and a few other little goodies.
I've been puttering around on it for a few days, and today I rode it to work, it was nice, but man, single speeds suck for commuting.
I love the clean look of a fixie, and its light weight ( aprox 20lbs, don't have a scale ) but if I keep up on it I may sell it and buy a road bike in the 500 range.
