It was everything my son was looking for. The bike was deliverd ontime and in great shape. If you've never put a bike like this together I would suggest you take it to a bike shop like I did. Only $35 to have the bike put together. The bike shop had the same bike for much more $$$$$ than what I paid on Amazon.
