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. The PowerMore would typically be mounted on the eBike down tube. There are 2 cables types, available in various lengths depending on where the charging port is on your eBike. The cable can exit the connector and either go "up" or "down." If in doubt contact your eBike manufacturer.

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.


  • Additional eBike battery pack
  • for Bosch Smart System electric bikes
  • compact water bottle design
  • 6.7Ah, 250Wh additional energy
  • 1.6 kg lightweight
  • Plug & Play installation


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.


  • 1x Bosch PowerMore Range Extender
  • 1x PowerMore battery mount
  • 1x bottle holder
  • 2x M5x12 mounting screws
  • without connection cable


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.

Why do I need an additional cable to retrofit PowerMore 250?

The external cable connects the battery to the eBike system. Because the required cable length and direction varies depending on the frame design, the cable must be ordered separately. 


Attach the PowerMore Battery Mount to the bottle holder mount. This mount remains permanently on your bike and can hold either the additional battery or the specialised bottle holder. If you want to use the PowerMore Battery, simply click it into the holder and connect the battery to your charging port. The appropriate PowerMore connection cable is not included. You have the option to choose from different lengths and cable exits based on where you intend to place your PowerMore 250.

Great company to buy from. Good and timely comms. Prompt delivery and responsive when resolving issues. Would buy from them again, without hesitation.

Received a fantastic service from Matt, he answered all the queries before the purchase and helped with a query once the scooter was delivered! I highly recommend Horizon e-bikes and I wouldn’t look elsewhere in the future when I come to upgrade my mountain bike

Really great buying experience.
The bike was sent off for delivery the same day I confirmed my order, email correspondence was very fast (thanks Matt!), and they partially assembled the bike for me. Would definitely recommend, especially for anyone looking to buy a Tenways bike living in London.

5* star service.
I recently bought estarli 28.8 pro from Horizon eBikes. Though I live in London, I went to Reading to buy my bike because one of my colleague recommended me Horizon eBikes and I wasn't disappointed, Matt is a such nice and helpful person. I was confused with accessories to buy along with the bike and he provided me a detailed list. The bike was ready, fully charged when I got there and I left there riding it.
Reading is a such a beautiful place.
Definitely recommend.

Horizon eBikes are top quality! Matthew was very helpful, friendly and the service was very quick and efficient!
I commend and recommend them! 5 Stars!

London, UK

Simply amazing! I applied to buy a bike through the Green Community initiative and was surprised how easy it was with horizon! I got my bike within a week. Matt was particularly very helpful and I ended up buying more stuff such as an air pump on the day of the delivery. Highly recommend
