When the bike first came I put it together and found that the front sprocket had gotten bent in shipping. I called the distributor and they immediately sent me out a new sprocket. I have been riding the bike for a couple of weeks now and it has been great. The dual suspension is wonderful when going over jumps. My only problem with the bike is trying to get to it before my oldest child does. I would recommend this bike for anyone looking for a solid and inexpensive mountain bike.
