Developed with ergonomics experts

The Purion 200 is mounted on the left-hand side of the handlebar, in immediate proximity to the thumb. Thanks to its curved shape, the combination of control unit and display fits beautifully onto the handlebar. If the plus and minus buttons are aligned correctly – i.e. almost vertically – this means more comfort for you during operation and a faster reading of the riding data. For example – with just one thumb movement, you can control your eBike and change the riding mode or the display. For the optimal combination of functionality, comfort and design, we have developed the Purion 200 jointly with the ergonomics experts from SQlab.  

Optimal readability

High resolution, more color depth, a clear structure and easy-to-understand symbols ensure that you can quickly read and grasp the information on the Purion 200. The integrated ambient light sensor automatically adjusts the brightness of the display depending on the ambient light. This makes it very easy to read, even in bright sunshine or at night.

Powerful display combinations

If you want more information or a larger display for even better readability, you can use another display in addition to the Purion 200: Have the Kiox 300 or Kiox 500 mounted by a eBike dealer or use your smartphone as a second display using the SmartphoneGrip and eBike Flow app. The additional new main display is controlled via the buttons on the Purion 200. The Purion 200 continues to show you the information that was last selected: You can, for example, display the current speed on the Purion 200 and use your main display for navigation.

Wide range of functions

The Purion 200 offers numerous functions that let you ride and arrive better. In addition to basic functions (such as switching your eBike and the light on and off) you can, for example, also activate the smart walk assist via the Purion 200 buttons to push your eBike more easily when walking. At the touch of a button, you can change the display in seconds and simply select the information that is important to you at that moment: for example, keep an eye on the remaining range, see the distance you have already ridden or check your cadence.

Connected intelligently

Five buttons, one display and lots of options: the Purion 200 is networked in the smart system and connects the eBike with the eBike Flow app. This gives you digital functions that you can easily activate and use via the app – e.g. for greater theft protection, recording your activities or the option of adapting riding modes to your needs. In addition, the Purion 200 is the interface for transferring updates to your eBike. This means that it always stays up-to-date.

FAQs & more

By removing the main display (e.g. Kiox 500), the desired display can be set on Purion 200. After attaching the main display, you can control it using the Purion 200 buttons.

Purion 200 contains a long-life and replaceable 75 mAh lithium-ion battery, which is charged via the eBike battery. Replacement can only be carried out by a dealer.

If your eBike with the smart system is currently equipped with an LED Remote, then a subsequent switch to Purion 200 is possible. Purion 200 then replaces the LED Remote, as your eBike can only ever have one control center. If you want to have this conversion carried out, please talk to your dealer in advance: Only they can carry out the replacement, as software adaptations are also necessary so that the new control center can communicate with your eBike.

Is your eBike with the smart system currently equipped with a System Controller? As this is permanently integrated in the top tube of your eBike, a switch to a different control center, e.g., located in Purion 200, is not possible.
