I'm considering upgrading my fixed gear to something with fatter tires. Current bike is a Motobecane Messenger which can barely fit 28mm tires. I'd like to run at least 32's maybe bigger. The closer to free ti is, the closer it is to my price range. I'm familiar with the BikesDirect offerings (both their "track bikes and 29er mtb's) but I'm wondering if there are other inexpensive fixed gear bikes I should be aware of that can clear big tires. Again cheap is king here- I know several 'bike shop brands' offer SS cross bikes and recreational bikes but i can't afford another $600+ bike.
