2021 NOTE: Due to the pandemic and difficulties in the delivery chain arising worldwide & extreme demand for our bikes at the same time, we reserve the right to replace some parts with those at the same level of performance (e.g. different brand, the same level of parts) to keep the overall quality of our bicycles. We’re sorry about that. At the end of the day, riding a bike is the best way of #staypositive ever, no matter what brand your handlebar or any other part is!

Customers are always advised to discuss specific details with the supplying Dealer, especially if a selection is dependent upon one of the features advertised.* The range of the e-bike depends on many factors such as the rider's weight, the track profile, the level of assistance, gear settings, the wind, etc., so the information is indicative and may vary.
