Compatibility answer

Will the Bosch PowerTube 750 horizontal (the smart system) work with the Bosch Performance Line CX drive unit (the smart system)?

Yes. Both use Bosch smart system PowerTube (horizontal-insertion version).

Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.

Why

  • ✓ Both use Bosch smart system PowerTube (horizontal-insertion version).

Good to know

  • PowerTubes are built into the down tube and the frame is designed for one length: Bosch lists smart-system PowerTube 500 at 345 mm, 625 at 415 mm and 750 at 484 mm long. A different capacity only fits if the bike maker approves it for that frame.
  • Horizontal and vertical PowerTubes are separate versions (different part numbers, e.g. PowerTube 750 BBP3770 horizontal / BBP3771 vertical per Bosch's manual); buy the orientation your frame uses.
  • PowerTube 500 and 625 also exist for Bosch eBike System 2 under the same names; those do not fit this interface.
  • 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).
  • Safety: use only batteries and chargers the drive-system maker approves. Lithium batteries that don't match can overheat.
