The problems I have with this bike was first; the bolts, washers and nuts were not in a bag. They were just loose inside the box. I had to search for every item that I needed. I had just originally thought that the pieces weren't included until I found one of the washers lying on the floor. Then I started searching inside the box until I found everything. The second problem I had with the bike was that the tires were flat. So I would not recommend this product.
