The Bosch PowerTube 500 Horizontal (BBP3750) provides 500Wh of capacity in a horizontal frame-integrated format for Bosch Smart System eBikes. Designed for frames that orient the battery tunnel horizontally — common in step-through, specific full-suspension, and some cargo frame designs — it delivers reliable range with a compact, integrated profile.

  • 500Wh capacity offers solid range for commuting, trail riding, and everyday Smart System use
  • Horizontal mounting orientation — designed for frames with a sideways battery tunnel
  • Bosch Smart System exclusive — integrates fully with Smart System motors and displays
  • Supplied with hazardous-goods compliant transport packaging and operating instructions
  • Supplied without mounting plates — confirm frame compatibility before ordering

The PowerTube 500 Horizontal is fully enclosed within the frame for a clean silhouette. Its 500Wh capacity suits riders who cover regular distances and want a lighter battery option while still getting meaningful range from their Smart System drive unit.

Compatible with Bosch Smart System eBikes only. Not compatible with older Bosch systems. Always confirm part number BBP3750 against your frame's battery specification — horizontal and vertical batteries are not interchangeable between frames.

Bosch provides a 2-year warranty on eBike batteries. Warranty claims for this product should be directed to Tune Cycles. Return the item to us with proof of purchase and we will manage the warranty process with the brand on your behalf.
