I bought this bike for my 13 year old son for Christmas, and the front wheel bearing failed after 2 weeks. The manufacturer sent out a new front wheel right away, but it was the wrong size for the bike we purchased. Now, after 4 months, we still do not have a new wheel and the bike has been sitting in my garage collecting dust. There are no local shops that carry the parts we need. I found an online store that would ship the new tire, and the manufacturer even agreed to pay the fee, because they could not procure the part. After waiting 3 weeks for the new wheel to arrive, we found out that it is coming from the same manufacturer, and cannot be shipped because the parts are not in stock. My son is devastated that he cannot use his new bike. His favorite Christmas present is now upsetting to look at everyday we pass it in the garage. Do not buy one of these bikes. Get something local that you can find parts and support for, if needed. I would suggest visiting a local bike shop and getting advice from them prior to purchasing.
