I wouldnt buy one, the hubs are crap unsealed cup and cone units and wont see out a winter, the wheel set making up a major part of the expense of a basic fixie, I would be wanting the formula/system EX cartridge bearing hubs or not bother at all unless the frame was really special, which the charge frame isnt.
I have seen Kona Paddywagons and Langsters on sale for less than the Charge and they have the cartridge bearing hubs as well
The Charge is cashing in on courier chic, there is nothing special about the charge bikes over other fixies that you couldnt change yourself with half an hour in the garage
Look beyond the superficial image and at what you get for the money in the running gear department, the charge falls short by a long way.
