Experience everything that your eBike can do! This update for the eBike Flow app is full of helpful functions that make your eBike more versatile – and every ride more enjoyable. With the performance upgrade and the new eMTB+ riding mode, you can choose your riding experience – from gentle and long-lasting to powerful and dynamic. We are also adding four new premium services to our Flow+ subscription: Easily share your eBike with up to five people and protect your battery with Battery Lock. Keep track of everything with the new annual overview and an optimised 3D map display for the ride screen.

More power when it counts. In everyday life and for your adventures.

Our drive units are getting stronger: more power, more torque or more support. When you want it, or all the time. Because you can decide whether and when to set these performance values in the eBike Flow app. You can customise your motor precisely to meet your needs and the distance you are travelling.

You can adjust the performance values for the following drive units of the smart system:¹

Cargo Line (BDU384Y)
Performance Line PX (BDU347Y)
Performance Line Speed (BDU388Y)
Performance Line CX (BDU384Y)
Performance Line CX (BDU374Y)
Performance Line SX (BDU314Y) (from autumn 2025)

This is how it works: After you have updated your eBike, you can set the performance values via the custom riding modes in the eBike Flow app. You can adjust each value using sliders. One new feature is the "Max. power (watts)" tile. It appears automatically as soon as you have updated your eBike. Here you can customise the maximum power in 25-watt increments.

Note: If you have an eBike with Performance Line CX (BDU384Y), you may need to take some additional steps. For this, follow the instructions in the eBike Flow app.

Power meets Control. The best of both worlds.

With the new eMTB+ riding mode, you can experience dynamic support to the limit. It combines the precise controllability of eMTB mode with the full power of Race mode and closes the gap between the two modes – with maximum support of 400%. The Extended Boost can be sensitively controlled as in eMTB mode and can develop the full power as in Race mode. This is because it develops its power in a natural and agile way, depending on your pedal input. Transfer the eMTB+ mode to your eBike via the custom riding modes in the eBike Flow app and configure it to meet your needs.

The eMTB+ mode is available for the Performance Line CX (BDU384Y), Performance Line CX (BDU374Y), Performance Line CX-R (BDU386Y) and Performance Line CX Race Limited Edition (BDU376Y). For the Performance Line SX (BDU314Y) from autumn 2025.

Share your eBike. With family and friends.

Sharing is fun. And that's true of eBiking too. You can now share your eBike with up to five people. This way, they too can enjoy an even better riding experience with the eBike Flow app. To share your eBike with friends and family, only you need a Flow+ subscription – but not your invited secondary users. As the main user, you retain control. Only you can enable and disable important functions, adjust basic settings, install updates over-the-air and store data in the eBike Pass.

It's so simple: You send the invitation via a link that you can create directly in the eBike Flow app. To send the invitation link, open the "Share eBike" menu item in the eBike settings and tap on "Create invitation". The secondary users you have invited simply have to accept the invitation and connect the eBike – then they can use the functions of the eBike Flow app.

Lock your battery digitally and relax when you park your eBike.

With Battery Lock, you can also protect your eBike battery digitally. If your battery is stolen, this function disables it and makes it useless to thieves. This means you can protect one of the most expensive components of your eBike and park your eBike with even more peace of mind. Battery Lock comes exclusively with the Flow+ subscription.

This is how it works: In the "Lock & Alarm" settings, you can select the battery you want to lock. Battery Lock is automatically enabled as soon as you switch off your eBike or remove your display – in just the same way as with eBike Lock.

The different digital keys that you can use at the same time give you flexibility: your smartphone with the eBike Flow app and your Kiox 300 or Kiox 500. With the eBike Flow app, you can manage your digital keys at any time – or switch off Battery Lock again in the "Lock & Alarm" settings if you want to share your battery with friends, for example.

Your annual overview at a glance:

Flow+ gives you an annual overview of your rides. This allows you to track your progress over the years. You'll find an overview of the most important ride data each year at the top of your statistics. It includes the number of rides, the distance travelled, the riding time and the elevation. You can also see how much CO₂you have saved. These useful statistics are linked to your account and apply to all the eBikes registered in the eBike Flow app.

Your route. In 3D.

The ride screen now offers you a 3D map display of the terrain. Regardless of whether you are tackling a mountain or enjoying nature on flat terrain: You can see a graphical visualisation of the elevation graph of your immediate surroundings. The three-dimensional display of prominent buildings makes it even easier to navigate through cities. You can also use the 3D map display without active navigation and for route planning. This premium service is available with the Flow+ subscription.

Adjust the traction control to your riding style now – for more control on technical sections. You can switch the Drivetrain Tensioner on and off for each riding mode, and with Trick Check, recorded tricks remain visible for longer. The remaining charging time for your battery appears on your display while you are charging.

With this update, you can fine-tune your setup for noticeably more precise control on the trail. You manage Extended Boost in the eBike Flow app, while Drivetrain Tensioner transforms your power into propulsion. The eBike Assistant answers your questions, and eShift lets you skip multiple gears at once.

The trail becomes a challenge, the route an adventure. The new Trick Check function automatically recognises your tricks, shows them on your display and saves them in the eBike Flow app. You can now also see your heart rate data and save your favourite places as favourites. We are also expanding the eShift portfolio.
