The versatile power source: PowerPacks from Bosch come in a variety of types. Frame batteries are close to the bike's centre of gravity. This has a positive effect on riding behaviour. The rack variant is ideal for step-through models (only available in Bosch eBike system 2), offering greater freedom when mounting or dismounting. Charging is very simple in both variants: for charging with a Bosch charger, the PowerPacks can be easily removed with just one hand movement or conveniently charged on the bike itself. The high-quality, long-lasting eBike batteries from Bosch combine high energy density with a compact size and light weight.
