My 14 year old son was happy with the bike at first, and does not ride his bike "hard". My older son remarked on the frame welds being sloppy and not ground down. Within 2 weeks a pedal broke(plastic), the sprocket is warped and the bearing in the rear hub is shot and he can't pedal it until we put more money into it and get it repaired. To replace what's broken it will cost us another $85.00 (on the low side). My son is not happy now - nor am I.
