Bike actually fast and simple to install. Seems solid, and beautiful finish compared to other products. Pedaling force into 8 average maximum strength, but still adequate. Silent. Saves space, stands alone in vertically and runs great, easy to handle. However, I also met a length of wire problem between the two connectors. Thinking he was stuck inside the tube, I pulled a little on it to seal ... Well, it holds for now, but it is clear he lacks a good centimeter wire. .. Surprising as workmanship!
