Storing or transporting your e-bike without a battery means the battery bay is exposed to the elements. You can easily fit a Bergamont Downtube Cover to protect the interior from rain, dirt or foreign objects. The cover is made from Neoprene and snugly fits over the bike's down tube to cover the battery bay. Please take note of the rules and regulations concerning the transportation of e-bike batteries. These may be considered hazardous materials in your country and may require special precautions when being stored and/or transported outside of the bike.
