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!

Manufacturers reserve the right to vary specifiations, including colors, with or without notice at such times in such manner as deemed appropriate. Major as well as minor changes may be involved.

This presentation shall not constitute - under any circumstances whatsoever - an offer by the Company to any individual. All sales are made by the Distributor or Dealer subject to and with the benefit of the standard Conditions of Sale and Warranty provided by the Distributor or Dealer, copies of which may be obtained upon request. While efforts are made to ensure specification accuracy cannot always immediately reflect either change in specification or in some isolated cases the provision of a particular feature. 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.
