I bought this bike for my 10 year old son instead of a similar one at Wal-mart thinking that it would be a better quality bike. Not the case - overall quality was probably the same but the brake adjustments were very complicated!! The bike went together easily but the brakes were not adjusted correctly (the wheels wouldn't even turn) and it took me 2 hours to just get them to work (and I'm a mechanical engineer!). The front brake assembly is still way too loose and I haven't been able to figure out how to adjust it. If I had bought one at Wal-mart, I would not have had to spend time adjusting anything.
