Bosch batteries are an efficient energy provider and the most modern eBike batteries on the market. They combine impressive mileage performance, a long lifetime and low weight with an ergonomic design and simple handling. The high-quality lithium-ion batteries are equipped with a Battery Management System, which recognizes potential sources of error and protects the cells from overload.With the PowerTube 500, Bosch offers a rechargeable battery that can be optimally integrated in the bike frame. There are two options for installing the battery, positioning it either vertically or horizontally. Minimalist design opens up new possibilities for integration into the frame for bike manufacturers. The battery is concealed and perfectly protected by the frame. A convenient function means that the battery pops approx. 2 cm out of the frame when unlocked, making it easier to handle. In addition, a safety mechanism prevents the battery from falling out. The battery is also optimally protected by the frame. Recesses in the top surface are suitable for attaching bottle holders or design trims.
