Enhance your ride, expand your adventure, the eBikemotion X35 range extender for use on any eBike with the eBikemotion X35 system. Orbea Gain, Pinarello Dyodo,  Wilier Cento1 Hybrid, Bianchi Aria. Nothing about these units is specific to a particular brand. Go farther with the new external charger for Gain and Optima. This new charger makes bigger challenges and longer adventures possible, providing nearly 2 hours of additional boost at maximum power assist — something unheard of in the industry.

When attached to Gain or Optima, the external device charges the bike's main internal battery, which has a current capacity of 248W / h, and adds an additional 208W / h to the Ebikemotion X35 systems. This brings the total battery capacity to 450W / h, giving a 70% boost to the internal battery's charge.
