The Bikechef app paired with our Bikechef connector allows full control of your e-bike battery. This gives you an overview of how much has already been charged and you can also limit this charge to a certain % range. This protects the expensive lithium-ion battery of your e-bike optimally and can therefore last for years longer. You can also plan a charge using the charging timer and monitor your charges using our charging statistics. With our winter mode you can store your e-bike with an optimal charge level over the winter and you don't have to worry about "battery aging" over the winter.
