The Performance Line CX reacts more sensitively to your input than ever before.

Bosch has reinterpreted and improved the signals from the sensors.

The cadence sensor measures how fast the cranks are turning.

The torque sensor measures how much force is exerted on the pedals.

Acceleration and position sensors detect how the e-bike is moving.

The Drive Unit does exactly what you want - sensitively, controlled and directly.

All options. Your choice
The higher torque ensures stronger acceleration. The increased maximum power makes best times possible. The increased support quadruples your own power.

eMTB+ mode
With the built-in "Dynamic Control", you ride with full control, even if you have increased your performance values. In steep, bumpy riding situations, you have superior propulsion and on loose or wet surfaces it is like traction control.

eMTB mode and Extended Boost
The eMTB mode reacts progressively to you and recognizes in a flash how much power you want based on your pedal pressure - dynamically, with maximum traction and always in control. With the integrated Extended Boost, all it takes is a targeted kick on the pedal and the Drive Unit pushes you effortlessly over steps and stones.

Push assist and hill start assist
With the push assist, you can easily push your eMTB, while the Drive Unit automatically adjusts the pushing speed to the incline and surface. In addition, the hill start assist enables a controlled and high-traction start, even on steep terrain. Hill Hold is active in both cases: your eMTB stays in place and does not roll back unexpectedly.

Bosch eBike ABS Pro
ABS Pro is ideal for professional eBikers: designed for fast, sporty downhill riding and braking. You can make full use of your braking skills and still feel how the system increases performance.

eShift with TRP
You can decide whether you want eShift with TRP to shift gears automatically for you or whether you want to change gears yourself on varied terrain with fast maneuvers - simply at the touch of a button. With eShift, gear changes are efficient and precise.

PowerMore 250
Compact and 1.5 kilograms in weight, the range extender can be easily attached to the water bottle holder. It can be combined with all batteries in the smart system. Please find out in advance whether you can use the range extender for your eBike.

Individual riding modes
Your trail, your riding experience, your mode: with the help of four parameters, you can easily adapt the riding modes to your needs using the slider in the eBike Flow app. Support, dynamics, maximum torque and maximum speed - you decide what you need.

Bosch eBike Flow app

Extend the eBike
Use the eBike Flow app to download new functions and updates for components such as the battery or motor and send them to your eBike via Bluetooth. This keeps it up to date and gives you more options.

Record activities
Record your tour and fitness data as soon as you set off. For iPhone users, Activity Tracking also synchronizes all data automatically with Apple Health if desired. If you take a break, the recording stops automatically.

Individualize riding modes
Customize the riding mode exactly to your needs: You can fine-tune the Eco, Tour, Sport and Turbo riding modes so that they offer you more support or consume less power.

Keep an eye on everything
Get a quick overview of everything important on the home screen. Whether battery status, remaining range, distance already ridden or next service appointment - the home screen shows you everything you need to know with constantly updated eBike data.

Bosch Kiox 300 display

Fun features
The robust display is an intelligent companion for sporty rides to determine fitness data and to optimise your training. Kiox 300 always stays up-to-date thanks to regular updates over the air and ensures optimal flow with further future offers and new features via the eBike Flow app.

Easy to read, sleek design
Small but powerful. Kiox 300 impresses not only because of its compact size, but for its colour display which ensures optimum readability by day and night. Operation via the LED remote is simple and is visually supported by animations and images. The handy display underlines the sleek eBike look and is protected against water splashes and dust.

Helpful support
An end to tedious pushing. The new Walk Assist function can be activated via the LED remote and supports the rider on particularly steep climbs. Kiox 300 provides clear, visual guidance and facilitates intuitive operation. The display also supports you before or during the ride by clearly showing you the remaining range for all riding modes. This allows you to better assess which riding mode can be used to reach your destination.

Positioning as desired
The display mount allows for centralised positioning of the display on the handlebar and is adjusted as per your personal preference. The tilt angle of the display can also be individually adjusted — for optimum readability during the ride.

Bosch LED remote

Optimal readability
For less distraction and more safety. All important information can be captured quickly and easily thanks to the LED remote. The LEDs are also highly visible in sunlight, and the brightness of the display adapts flexibly to the ambient light: This means that readability is maintained even in changing light conditions and you are never dazzled. You can also quickly recognise the selected riding mode by the respective colour.

Smart connectivity
Greater flexibility, comfort, and safety: The LED remote connects the eBike with the eBike Flow app. This enables you to call up all important riding data, such as the duration of your ride or the distance covered, using your smartphone and to share this with other users. It is also possible to carry out software updates independently.

Smart Walk Assist
Even on the steepest of trails, when riding is no longer an option, you can push your eBike more easily with the help of Walk Assist: Simply press the minus button, move the eBike and you will already feel the support. The LED remote also acts as your guide, making handling easier for you. Walk Assist is especially helpful when eMountain biking in challenging terrain.

Ergonomic handling
The LED remote can be individually adjusted to you and, in addition to an attractive design, boasts optimal ergonomics and intuitive operation. Thanks to the ergonomic 'L' design, the LED remote can be attached to the handlebar so that you can reach and operate all buttons perfectly with your thumb.

Sustainably on the move
Reach your destination safer and more sustainably: The long-life rechargeable battery of the LED remote means that you can rely on the control centre on every single eBike ride. If the battery does ever need to be replaced, it can be ordered by a specialist dealer because the next route is already waiting to be discovered!
