My 12 year old daughter was delighted. The quality seems good. It came nearly assembled in the box, just put the seat and wheels and pedals and handlebar on, but the instructions were not so good. No complicated stuff, under an hour with your hex keys. Front disk brake is amazing, but no quick release. Gears worked well without adjustment, and she was able to shift up/down easily.

This is a beautiful bike; however, I am still trying to get all of the gears adjusted. My suggestion is just to take the entire box to a bike store and have them put it together and do all of the adjustments to save a possible headache. Overall it is a great product for the price.
