System Controller
Minimalist, robust control unit
Reduced to the essentials, the System Controller is the control unit for eBikes with the smart system. The scope of functions and information is deliberately limited – so you have a quick overview that won't distract you when riding. The System Controller is seamlessly integrated into the top tube – this gives the already robust companion additional protection, is hardly noticeable and is perfect for sporty tours and design-oriented eBike fans.

Quick overview
Register important information quickly: The functions of the System Controller are reduced to the essentials. The different colours of the riding mode LED each represent a different riding mode. You can also check the charge status of your battery via the LEDs. If they all light up blue, the battery charge level is 100 percent. If an LED turns white, it means the charge level has decreased by ten percent.
Smart control unit
Benefit from connected riding with the smart system: As part of the new system generation, the System Controller is the connecting element between your eBike and the eBike Flow app. It serves as an interface for transferring software updates from the eBike Flow app via Bluetooth to your eBike and is an alternative to the LED Remote. The System Controller also lets you use smart functions like eBike Lock.
Cleaner look
Enjoy the understated design of your control unit: Since the System Controller is permanently installed in the frame of the eBike, it is barely noticeable at first glance. In addition, its hard material surface makes it particularly robust. The clean bike look is maintained and you have a strong companion on trails that scratches and impacts can't harm. Its battery is durable and can be replaced in an environmentally responsible way.
Good operability
Control the most important functions of your eBike with just two buttons. These let you turn your eBike on or off and change the riding mode. The buttons are arranged and designed so that you don't need to take your eyes off the track while riding. The soft-touch surface prevents slipping and enables intuitive, error-free operation.
A perfect addition: Mini Remote
Use the Mini Remote to operate your control unit even more safely and comfortably: The Mini Remote can be easily retrofitted to the System Controller and mounted by you independently on the handlebar. Now you never need to take your hand off the handlebars while riding and have three more buttons that expand the range of functions. Once the Mini Remote is in place, you can also control a display or use your smartphone as a display.
Optimal readability
Always recognise immediately which riding mode is currently in use and how much battery energy is still available: The integrated ambient light sensor automatically adjusts the brightness of the LEDs to the current lighting conditions. This way, you can easily read the LED signals even in direct sunlight and won't be dazzled in the dark thanks to dimmed LEDs.
Individual riding modes
You can fine-tune the riding modes of the smart system so that they offer you more support or enable longer range.
eBike Lock with the smart system
Activating the eBike Lock function via the eBike Flow app lets you use your smartphone as a digital key. Because motor support can only be activated with your smartphone and Bluetooth connection, your eBike holds no attraction for thieves. You can also set up your Kiox 300 or Kiox 500 as a key for your eBike.
Even better protected with eBike Alarm
The Flow+ eBike Alarm premium service protects your eBike even more effectively against theft. In interaction with eBike Lock, it expands the locking of the drive unit with a comprehensive alarm function. When you switch off your eBike, eBike Alarm activates automatically. In the event of attempted theft, eBike Alarm reacts with alarm signals. If the eBike is moved, tracking is started.
You can control all functions of the smart system via the eBike Flow app. It allows you to adapt the eBike to your needs, upgrade it and keep it up to date. You simply download new features and services. You can conveniently install updates via Bluetooth. This keeps your eBike up to date and continuously upgraded with new features. Want greater theft protection? With Flow+ you get access to the eBike Alarm premium service to give your eBike even better protection.
eBike AlarmLess reason to worry when you park your eBike: With Flow+ and ConnectModule you can use eBike Alarm. Alarm signals deter thieves. If things get serious, location tracking is activated.

Route planning and navigationMini Remote and Mini Remote Dropbar
The Mini Remote and Mini Remote Dropbar complement the System Controller
As an additional control unit, the Mini Remote or the Mini Remote Dropbar complement the System Controller. They allow you to operate the eBike and display more safely, access more functions and use practical additional features such as the smart walk assist. You can also switch the eBike light on or off. Wirelessly connected to the System Controller, they can be flexibly attached to the handlebar: the Mini Remote for standard handlebars such as eMTBs, the Mini Remote Dropbar for handlebars with a larger diameter, e.g. for eGravel and eRoad bikes.

A perfect addition
Use the Mini Remote or Mini Remote Dropbar as a practical addition to the System Controller. The smart ergonomics ensure intuitive handling. For example, you can change the riding mode without taking your hand off the handlebars and therefore ride even more safely – whether on the trail or in the city.
Wireless design
Avoid cables that disrupt the clean eBike look: the Mini Remote and Mini Remote Dropbar are connected to the System Controller via Bluetooth and therefore don't require a cable connection. Despite the minimalist design and only three buttons, you can use the full range of functions.
Simple operation
You can quickly find the right function on the easy-to-grip, tactile buttons with a soft-touch surface thanks to the icons. Each button is assigned two functions. You can choose between them with a long or brief press of the button, which facilitates intuitive operation.
Hill Hold
The Hill Hold function prevents your eBike from rolling back unintentionally when pushing it on steep slopes or on steps. It complements smart walk assist. If you intentionally or accidentally release the minus button of the control unit while pushing, it automatically engages. Hill Hold prevents your eBike from rolling back for about ten seconds – without you having to apply the brake.
Mini Remote Dropbar
Now use the features and advantages of the Mini Remote with eGravel bikes and eRoad bikes: The Mini Remote Dropbar variant was specially developed for dropbar handlebars with a diameter of 31.8 mm and is mounted to the left of the stem. In conjunction with the System Controller, the CompactTube 400 battery and the Performance Line SX drive, it is the ideal control unit for particularly light and sporty eBikes.
FAQ & more
The five charge level LEDs indicate the charge level. A pale blue bar corresponds to approx. 20%, a white bar approx. 10 %. In addition, the display turns orange below 30% and red below 10%. Flashing red flashing at 0 % indicates that motor support is no longer available, but that there is still reserve power for light.
