The Bosch PowerTube 800 Vertical (BBP3881) delivers 800Wh of capacity in a vertical frame-integrated tube format — Bosch's highest-capacity Smart System battery in the vertical orientation. It suits full-suspension eMTBs, trekking eBikes, and cargo designs where the battery tunnel is oriented vertically and riders want the absolute maximum range from their Smart System eBike.

  • 800Wh capacity — Bosch's top-tier Smart System battery capacity in a vertical format
  • Vertical mounting orientation — fits the most common Smart System frame battery tunnel designs
  • Bosch Smart System exclusive — integrates with all Smart System motors, displays, and chargers
  • Supplied with hazardous-goods compliant transport packaging and operating instructions
  • Supplied without screw-on plates — confirm frame compatibility before ordering

The PowerTube 800 Vertical sits fully inside the frame down tube for an integrated, low-profile look. Its class-leading 800Wh rating makes it the go-to choice for multi-day tours, long eMTB stages, and heavy-duty daily commutes where range is non-negotiable.

Compatible with Bosch Smart System eBikes only. Not compatible with older Bosch systems. Always confirm part number BBP3881 against your frame's battery specification before ordering — vertical and horizontal variants are not interchangeable. Available in black or silver based on stock availability.
