I have been searching for an affordable single speed 29er for a year, and I finally found one. The Gravity G29 is a great bike, very affordable, large, stable front forks, dual disc brakes, all I've ever wanted in a bike. Shipping was 2-3 days, assembly was simple, runs like a charm. I may buy another one and put street tires on it to get around town as a commuter bike. The tires on it are the best mountain bike tires I've ever seen. I got the Size 21, because I am 6/3,200 lbs. Fits perfect. Recommend this to anybody who doesn't want to spend an arm and a leg on a bike and still get first class quality!
