Good to know
  • Only fits bikes whose rear rack is built for the smart-system PowerPack Rack; Bosch's page does not state that every rack takes both the 400 and 500 Rack, so confirm with the bike maker or dealer.
  • Not interchangeable with frame PowerPacks or with System 2 rack PowerPacks.
  • Bosch: 'Use only original Bosch batteries that the manufacturer has approved for your eBike' and 'Only charge the battery using original Bosch chargers'; Bosch warns other batteries/chargers can be a fire hazard (Bosch PowerTube 750 operating instructions, as hosted on ManualsLib).
