Important Note: We recommend that you only use the cover, when the outside temperature is below 15 °C. Furthermore, you should also remove it when charging to avoid overheating the battery.
Elegant Design: The battery protection from Wheeloo is well made and precisely adapted to your e-bike battery. The black matte material fits wonderfully to the conventional shape of the battery and therefore fits perfectly with your bike.
100% Perfect Fit for your E-Bike: The Wheeloo Neopre cover is precisely tailored to your battery. Whether Bosch Powerpack 300, 400 or 500 and regardless of the CX, Performance or Active Line product series, the battery protection fits perfectly and cannot slip while driving.
