As known, weather conditions affect the performance of any e-bike, such as the range, charging the battery, capacity of the battery and the electric support in general.
Under 20°C the capacity of the battery will drop with 1- to 2% every single °C degree. This means that you have only about 80% capacity left when the temperature of the battery is 0°C.
Store and charge the battery at room temperature. For charging, the battery temperature must be between 0°C and +40°C. When in use between -20°C and +80°C. For storage for a longer period of time between -10°C and +35°C.
Store the battery in a frost-free place and protected against large differences in temperature in a dry, well-ventilated room without direct sunlight.
We advice to take the battery out of the bike and store and charge it at room temperature. Only put the battery back in the bike just before you leave for your next trip to sure the maximum capacity of the battery can be used.
