The function of your bike battery depends on a good connection to the respective points on the bike. The Basil Downtube Electric Cap for Shimano Steps/Yamaha ensures that you protect this battery connection when the battery is removed – a must-have when transporting your bike on a bike rack, for example. The cover also protects the battery connection against splashing rain and dirt. The cover is made of 4.5 mm thick neoprene and offers reliable protection. The Electric Cap can be used on frame batteries of electric bikes with Shimano Steps or Yamaha batteries and comes in a slick black and lime colour scheme.
