The range of an eBike is among the first and most common concerns and questions we get asked here at EDEMO Electric Bikes. Fortunately, Bosch is at the forefront of battery development and is constantly innovating to improve range and reduce weight. There are options available to cover most eBike riders.

With the Bosch Range Extender Powermore 250, there comes an option that challenges the existing dual battery range with increased flexibility and options for riders that want to cover extra mileage without worrying about their battery life.

In this article, we’ll cover all the questions we are asked by customers so that you can understand whether a Bosch Range Extender Powermore 250 is the right option for you. If there’s anything else you’d like to know or you’d like to speak to use, we’d love to hear from you.

Bosch Range Extender Compatibility

Are all eBikes compatible with the Bosch Range Extender?

Bosch Smart System Required: The Range Extender is specifically designed for eBikes equipped with the Bosch Smart System. This system was introduced on eBikes from around model year 2024 onwards. Older eBikes using Bosch’s previous systems are not compatible.
Software Updates: Even with the Smart System, you’ll need to ensure your eBike has the latest software updates to communicate with the Range Extender. You can check this through the Bosch eBike Flow app. (details below).
Manufacturer Approval: The manufacturer of your eBike needs to have specifically enabled the Range Extender option. This is because they may need to provide specific mounting points or connections on the bike

How to Check Compatibility:

eBike Flow App: Connect your eBike to the Bosch eBike Flow app. Look in Settings -> My eBike -> Components. If the PowerMore 250 is listed, your bike is likely compatible.
Bosch Dealer: Contact your local Bosch eBike dealer for the most accurate compatibility information and assistance in enabling the feature if needed. We’d be happy to assist with any queries related to Riese and Muller ebikes. Just give us a call.
eBike Manufacturer: Check your eBike manufacturer’s website or customer support.

How is the Range Extender mounted on the bike and what is the connection between it and the motor?

The Range Extender is mounted onto the bottle cage mounts using a bracket. Consult your ebike manufacturer to confirm if you can do this.

The Powermore simply slides into place on the bracket and feels pretty secure when fitted. Of course you’re losing a potential mount for a water bottle.

The Riese and Muller bike pictured (Delite4) shows the connection on the motor and the cable that fits into this. The cable must be purchased in addition to the Powermore battery. The orange circles in the picture show the new clip receptor and the clip on the cable that needs to be present on the bike.

Once in place, it all fits pretty snugly and feels solid. It’s not quite as neat as a dual-battery bike such as the Supercharger, where both batteries are within the frame, so there are no loose cables; however, the system is certainly more flexible.

Functionality

How much extra range does the PowerMore 250 provide?

The Bosch Range Extender offers riders an additional range of approximately 10-25 miles. This extended range, however, is subject to various factors, including the weight of the rider and bike, the level of assistance selected (with Eco mode offering the best range), terrain variations such as hills, and other such considerations.

Can I use the Powermore 250 as a single battery?

The PowerMore 250 can serve as the sole battery on your eBike, but it’s important to be aware that this configuration will result in a decreased range due to its lower capacity. Additionally, the output power of the drive unit will also be diminished.

How does it integrate with my eBike’s existing battery system?

The Bosch Range Extender (PowerMore 250) integrates seamlessly with your eBike’s existing battery system through the Bosch Smart System. Here’s how:

Automatic Connection: Once you mount the Range Extender and plug it into the compatible connection on your bike, the Bosch Smart System automatically recognizes it as an additional power source.

Unified Capacity: The eBike’s display will show the combined capacity of both your main battery and the Range Extender as a single percentage.
Intelligent Power Management: The Smart System manages the discharge of both batteries.
Prioritizing the larger capacity first: The system will consume the battery with the most charge first, once this is depleted to the capacity of the Range Extender the system will then consume both batteries at an equal rate.
Charging: You can use your eBike’s standard charger (up to 4 amps) to charge both the main battery and PowerMore 250. However, you cannot charge them simultaneously unless you have 2 chargers. How much does the Range Extender Weigh?

It weighs approximately 1.6kg (3.3lbs) so it is light enough to maintain the balance of your bike or even to take an additional one in your bag for even more range.

Is the range extender waterproof?

It is IP65 rated, meaning it is highly protected from dust and can withstand rain and low-pressure water jets. However, it is not submersible. Provided it is mounted correctly, it is suitable for off-road use.

Cost and Availability

How much does the Bosch Range Extender cost?

The Bosch Range Extender is available as an extra on selected Riese and Muller bikes for £420 (Delite4 & Charger4) and £466 (Culture including a bag).

Where can I buy the Bosch Range Extender?
