I bought this bike to explore the sport of mountain biking on the local single tracks. I had to adjust the rear mech slightly to avoid the chain from falling off and had to adjust the brake tension slightly. I also got some no-flat tubes and another layer if rubber between the tube and rim as the spoke needles poke out a bit and would have caused a flat on the first real bump. Of course this bike will not compare to one with better components that usually start in the 700.00 range, but after about 150 miles of relatively rough terrain, it is holding up well. Gears are slow to respond and brakes need constant adjustments. However, it is a reliable hardtail that has helped me learn that i love mtb as much as road biking. I will upgrade eventually, but this is the best 80.00 i have spent on a bike. I have dropped it, crashed it, jumped it, mash it in the back of the suv and it still keeps on ticking. If you are going to ride every day or on trails, get thw upgraded tubes, another layer of protection under the tube, and the brakes right. Otherwise, beat it up while you save the remaining 1,000.00 for the next level up. I also put a road bike seat on, but that is only because i had it. The one that came with it was fine.
