We bought this bike for our 10 year old son. It was big and the seat height needed to be adjusted by cutting down the rod (the seat did not go down enough). We had a friend assesmble and he said it was a challenge...there was some damage on arrival. I know he will grow into this, but the heaviness of it has him a little gun shy. By summer it will be good. There's just no good in between, his other bike is too small. Otherwise, bike looks good and functions well.
