The optimal e-bike battery protection for a longer battery range on cool days. These neoprene e-bike battery protective covers ensure that the operating temperature is maintained on cool days, such as in winter, and optimally adapt to the shape of the battery. This reduces the self-discharge of the battery, which is why you achieve a longer range with the e-bike. This ensures even more riding fun on the next bike tour. 

Electric Bike Battery Tip: The battery should be stored at room temperature and only inserted into the e-bike shortly before the start of the journey.
