The Bosch PowerMore 250 is the additional drinks-bottle-sized battery for even more range and longer-lasting trail fun. Only suitable for Bosch SmartSystem eBikes.

Attention: Please note that the does not include a connecting cable for the charging port. You need to order this separately. 

Compact and weighing only 1.6kgs, the range extender can be easily stowed in your rucksack until you need it. If you can manage without it, your water bottle can fit in its holder. For rides with lower energy requirements, you can leave your main battery at home and rely fully on PowerMore 250 – this reduces the weight of your eBike. Please find out in advance from your eBike manufacturer if you can use the range extender for your eBike.

Can I retrofit PowerMore 250?

PowerMore 250 can generally be ordered as a retrofit product. You also need a cable, which must be ordered separately. You can find out the correct cable length from your eBike manufacturer or eBike dealer.

You can find out whether you can retrofit the PowerMore 250 additional battery to your eBike from your eBike manufacturer or via the eBike Flow app (  Settings > My eBike > Components). If you use an eBike display, you can find out via Settings > My eBike: If the menu item "PowerMore" is displayed here, you can retrofit the range extender.

No matter where your e-bike takes you, with the PowerMore 250 battery pack in your luggage, you always have a suitable energy reserve with you when you need to go further than planned. Stowed in your backpack or pannier, the 1.6 kilograms hardly weigh anything. If your main battery starts to run out of power, simply replace your water bottle with the Bosch Range Extender. All you have to do is insert the PowerMore 250 battery into the holder and connect it to your charging socket. Then the eBike fun can continue.


Finding areas of use for the Smart System Range Extender from Bosch is really no problem. On long tours, you will never have to worry about the way home again, on the trail you will be able to climb the hill with full power even after a long day, and in the city you will quickly have an energy reserve ready if you forget to charge your eBike. But the Bosch PowerMore 250 can also prove itself on its own. On short distances, you can use the range extender without the main battery and thus benefit from the significantly lower weight of your eBike.

Whether your e-bike can be equipped with the Smart System Range Extender depends on various factors. In principle, all bikes with the Smart System are compatible. To ensure communication between the PowerMore 250 and your bike, you must have the latest software installed on your system. You can install this software through the Bosch eBike Flow App. Additionally, the manufacturer of your e-bike - for example, KTM - must have enabled the Range Extender option. If this is not the case, please contact a nearby Bosch specialist workshop to enable the option if possible. However, this is only feasible if your e-bike also has the necessary and stable attachments. For this, it is best to directly contact the manufacturer of your e-bike.
