Also known as integrated batteries, these models excel in both performance and aesthetics: Bosch PowerTube batteries deliver the required energy while remaining nearly invisible on the e-bike thanks to their compact and minimalist design. The battery can be mounted either horizontally or vertically. This year, two new models are being released: the PowerTube 400 and the PowerTube 625. These lithium-ion power sources rely on sophisticated, frame-integrated technology to ensure worry-free rides, and safety features keep them securely in place even on rough terrain—while still being easily removable when needed.

DualBattery
Twice the energy
Nothing is too far: DualBattery is the ideal solution for touring cyclists, long-distance commuters, cargo bikes, and electric mountain bikes. Two Bosch batteries can deliver up to 1250 Wh combined, and the system can be configured from nearly any battery combination*. The system intelligently switches between batteries during charging and discharging.
- An energy management system ensures proper charging of both batteries
- Combining two batteries lets you travel twice as far
- Compatible combinations include: two PowerTube batteries, two PowerPack batteries, or one of each
- The Battery Management System protects the DualBattery setup from overcharging, deep discharge, overheating, and short-circuiting—while also extending battery life.
*Only the PowerPack 300 and PowerTube 400 cannot be used in combination with other batteries in a DualBattery setup.
