The range of the batteries, i.e. how many kilometers an e-bike battery holds, depends on many different factors. Therefore, only a royal assessment of the range can be given. The average range of a standard battery is between 50 - 70 km. The most important factors that determine how many kilometers a battery lasts are the capacity of the battery and the bike type.
See the average range for each bike with a standard battery in the chart below, this data was collected by field measurements from a number of app users. On the product page of a bike, you can also find the minimum and maximum range at the technical specifications.
