Reliable All-round Protection: Scratches, stone chips and dirt are now a thing of the past. The neoprene cover provides reliable protection and can be easily washed at low water temperatures.
Increase Your E-Bike Performance: Similar to your smartphone, the lithium-ion battery does not last as long it usually in low temperatures. A cold protection cover made from 4.5 mm thick insulating neoprene is therefore the best solution, if you do not want to run out of power on cold days.
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.
