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 drinks-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 centre of gravity, it ensures balanced weight distribution.

PowerPack batteries

The versatile power sources: PowerPacks from Bosch are visibly mounted on the eBike frame or luggage 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 batteries are located on the outside of eBike frame, on the seat tube or downtube. They feature a carrying handle so that you can remove them easily and carry them conveniently.

All frame batteries of the smart system use the same mount. You can simply insert another battery, provided the geometry of the eBike allows it. You can use a smaller battery to reduce the weight or a larger one to increase the range.

PowerPack 800 Frame is available in the smart system.

PowerPack Rack

Rack-variant PowerPacks are positioned on or under the luggage 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.

PowerTube and CompactTube batteries

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 eCargo bike, or shorter, everyday rides in the city.
 

CompactTube 400

Slim, integrated, compact and delivering 400 watt hours at a weight of only around 2 kilograms, 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 eGravel bikes or design-oriented eUrban bikes – in short, for anyone who loves the sleek appearance of conventional bikes but doesn't want to do without electric support.

Extended range

Battery combinations and additional batteries: One battery alone is not always enough. eCargo bikes put a lot of strain on the battery due to their higher weight, especially with a heavy load on board. On treks 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 maximise range.  

DualBattery

Use two batteries at once – for even more range: DualBattery is ideal if you want to travel long distances or ride an eBike that uses more energy, e.g. a Cargo eBike or speed eBike.

You can combine PowerPacks or two PowerTubes from the smart system. With two PowerPacks 800 Frame, you get up to 1,600 watt hours – and can travel up to around 188 miles*! From spring 2024, you will also be able to combine a PowerTube with a PowerPack.

DualBattery for the Bosch eBike system 2: The combination of two batteries delivers up to 1,250 watt hours.

FAQs

Range Extender PowerMore 250

Portable energy reserve: PowerMore 250 is the additional battery the size of a drinks bottle for even greater range and longer-lasting trail fun. Compact in size and weighing just 1.5 kilograms, the Range Extender can be easily mounted in the water bottle holder. The Range Extender can be combined with all batteries of the smart system. Please find out in advance, from specialist dealers, if you can use the Range Extender for your eBike.

FAQs & more

The range of Bosch eBike batteries depends on numerous different factors.

To achieve the highest possible range, consider the following:

Battery & temperature: With decreasing temperature, the performance of a battery is temporarily reduced because the electrical resistance increases. In winter, you can therefore expect a reduction in the normal range.

Cadence: Cadences of between 60-90 revolutions per minute are ideal.

Starting & braking: As with a car, frequent starting and stopping is less economical than long distances at (almost) constant speed.

Gear shifting: Correct gear shifting also makes eBiking more efficient: A low gear should be used when starting and on inclines, followed by upshifts according to the terrain and speed.

Tyre pressure: In order to maximise the range, ride with the maximum permissible tyre pressure.

Weight: The mass should be minimised by keeping the total weight of the bicycle and luggage from being unnecessarily high.

You can find out what range you can achieve with your eBike using our  range assistant.

When purchasing used batteries, it is essential to ensure that these are taken on without any damage from their previous owner. Damaged batteries are offered online from time to time; these pose a high risk and can lead to dangerous malfunctions. Sometimes, illegal goods e.g., from thefts, are offered online as well. No ownership can be legally acquired in such goods in accordance with section 935 of the German Civil Code.

You can hand in your old or defective eBike battery free of charge to any bicycle retailer, who will recycle it in an environmentally friendly way. No purchase of a new battery is required to do so.

Please note that heavily damaged batteries should not be touched with bare hands, as electrolyte may leak out, causing skin irritation. Please keep any defective batteries in a safe place outdoors, with the contacts taped off, and take them to your bicycle retailer for proper disposal as quickly as possible.
