Bike used only 20h, broken belt, the company provides no ULTRASPORT service despite the validity of warranty, no repair info, not even able to respond to emails in French, it sends you a copy / paste, and no news. You understand the politics of this seller. Belt made in China ... Knock! Product rotten. The company sells ULTRASPORT bike apart as if she was selling bread sticks dissociate herself totally customer service. One wonders why Amazon is taking the risk of this partnership and to deliver their product. STAY AWAY if ABSOLUTELY do not want to regret, and do not you be fooled by the attractive price. Some users seem satisfied (me too, the early days), we should be able to interview a few months after use .... We had to buy another better product elsewhere ....
The company responds Ultrasport later by sending a new bike, so everything is ok, this comment is closed and obsolete, thank you to Ultrasport for responsiveness and service.
