No distance is too far. Dual Battery upgrade is the ideal solution for tour riders, long-distance commuters, cargo bike users and eMTB riders. The combination of two Bosch rechargeable batteries delivers up to 1,250 Wh and can be installed by the bike manufacturer in almost any battery combination*. The system switches intelligently between the two batteries during charging and discharging. This ensures that both batteries are charged and discharged uniformly, which significantly extends their service life. You can also use just one battery depending on your requirements.
* PowerTube 400 cannot be used in a DualBattery combination.
