For many years of service

With our smart system batteries, eBike riders still have 80% of the original battery capacity available after 1,000 charging cycles.¹ 1,000 charging cycles correspond to a mileage of approx. 28,000 miles (45,000 km). With an average distance traveled of approx. 53 miles (85 km) per week; this means the battery capacity is still at 80% even after more than 10 years of use.²
