For many years of service

With our smart system batteries, eBikers 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. 45,000 km. With an average distance travelled of approx. 85 km per week; this means that the battery capacity is still 80% even after more than 10 years of use.²
