Packed with power

Bosch eBike batteries

Bosch eBike batteries are efficient, long-life energy sources. They combine low weight with ergonomic design and simple handling. Thanks to their impressive mileage, long service life and an intelligent battery management system (BMS), which protects the battery from damage, they are among the most modern and safest on the market.

Find the suitable Bosch lithium-ion battery for any requirement and for every eBike type: DualBattery is two batteries combined – ideal for heavy loads, extensive rides and long commutes.

PowerMore 250 is the drink-bottle-sized range extender for eBikes with the smart system.

Powerful in every design

Different battery positions

Frame battery

Because it is a frame battery, the PowerPack is easy to access and remove. Thanks to its low center of gravity, it ensures balanced weight distribution.

The versatile power sources: PowerPacks from Bosch are visibly mounted on the eBike frame or rear rack. Charging is very simple with both variants: For charging with a Bosch charger, the PowerPacks can be removed easily, or charged directly on the bike itself. The high-quality, long-life frame or rack batteries have a high energy density combined with compact size and light weight.

PowerPack Frame

The PowerPack Frame models are usually installed on the outside of the frame, on the seat tube or downtube. They feature a carrying handle, so they are easy to remove and convenient to carry. In addition, frame batteries are close to the bike's center of gravity: This has a positive effect on riding behavior.

Because all PowerPack Frame variants for the smart system have the same mount, you can simply insert a different battery pack – provided the geometry of your eBike allows this.

PowerPack400 Frame is available in the smart system.

PowerPack Rack

Rack-variant PowerPacks are positioned on or under the rear rack. For eBikes with a step-though frame this battery position has advantages – greater freedom, for example, when mounting or dismounting. In addition, thanks to their higher position on the eBike, the powerful batteries can be easily and conveniently attached and removed. The greater distance to the ground also protects them from water splashes and any impact from stones.

In the smart system are the PowerPack 400 Rack and PowerPack 500 Rack available.

For the highest demands in terms of performance and aesthetics: Bosch PowerTubes blend ideally into the clean design of the eBike – they are integrated into the frame tube. They come in two variants, horizontal or vertical. Both are installed directly by the manufacturer to match the relevant eBike model. A safety catch prevents the battery from falling out. Where provided for, however, the batteries can be easily and conveniently removed.

PowerTube

Discreetly integrated into the frame tube, these high-quality power sources are barely noticeable. Bosch offers numerous PowerTube variants, with different energy contents, in the smart system and in the Bosch eBike system 2. So you're prepared for any challenge – whether it's sporty riding on trails with your eMTB, energy-sapping uphill riding with a fully loaded Cargo bike, or shorter, everyday rides in the city.

CompactTube 400

Slim, integrated, compact and delivering 400 watt hours at a weight of only around 4.4 lbs, it's a real energy champion: The CompactTube 400 with innovative battery cell technology offers the highest energy density of all Bosch eBike batteries. This makes the extra-lightweight battery the ideal choice for sporty, light eMTBs, minimalist Gravel eBikes or design-oriented Urban eBikes – in short, for anyone who loves the sleek appearance of conventional bikes but doesn't want to do without electric support.

Battery combinations and additional batteries: One battery alone is not always enough. Cargo bikes put a lot of strain on the battery due to their higher weight, especially with a heavy load on board. On tours lasting several days with completely filled saddle bags, a full battery makes for more carefree riding. You've discovered another trail you simply don't want to miss? For these and other cases, Bosch eBike Systems has developed solutions to maximize range.

DualBattery

Use two batteries at the same time: DualBattery is the perfect solution for tours, long distances or transporting heavy goods that require large energy reserves. The system switches intelligently between the batteries, so they are charged and discharged evenly, which increases the service life. In cases where you need less power, you can simply leave one of the two batteries at home.

DualBattery will be available for the smart system from 2024. Please find out in advance, from eBike dealers, whether you can use DualBattery or not.

DualBattery for the Bosch eBike system 2: The combination of two batteries delivers up to 1,250 watt hours and can be installed in almost all battery combinations from the eBike manufacturer.

Batteries and recycling

Maximum service life

The ecological footprint of an eBike is determined by the production, use and recycling of the battery. That's why we do everything possible to maximize their service life and to ensure proper disposal. You can find more on the subject of batteries in our battery guide.
