Good overall.

The main thing, the price, seems high to me, but as the market is, average. Assembly was quick in the store. So fast that I had to do a little review at home. The bike had a defect, a damaged fork sticker, in the store they told me what was wrong and in customer service that they could only give me a solution in the store. That's mainly why I don't give it more stars. The bike, beautiful and adequate, that for the price it has, I expected no less.
