Full power for the ultimate Uphill Flow
The Performance Line CX is a powerful and dynamic drive – for intuitive handling and a unique riding sensation. Thanks to the multi-sensor concept and the innovative Bosch motor control, the Performance Line CX sets new technical standards: It responds flexibly, with great sensitivity, and unfolds its full potential on technically demanding trails. One effective feature is eMTB mode, which applies exactly the right amount of power from Performance Line CX, allowing you to focus all your attention on the ride. In the eBike Flow app, you can adjust the support, dynamics, drive torque and maximum speed of your eBike in the riding modes Eco, Tour, Sport and Turbo, to suit your individual needs.




Strong support
The Performance Line CX is the benchmark among drive units. Weighing 6.3 lbs and with a maximum torque of 85 Nm, it brings more fun to the trail on demanding rides despite its particularly compact size. This drive unit is compact, lightweight and extremely powerful, it combines high-quality materials with high-end sensors.

Powerful support up to 2o mph, even on steep mountain rides
The Performance Line CX - for the smart system

A real powerhouse
The maximum torque of 85 Nm has a noticeable effect on your riding performance when eMTB riding. The powerful motor enables rapid acceleration after tight turns and obstacles at a low cadence and facilitates starting up on the steepest of hills. For fast sprints, the motor also supports you at high cadence.

Intuitive handling
Specially designed for sporty use, eMTB mode offers you optimum control and intuitive handling, as you need to switch less between the different riding modes. With this clever function of the eMTB mode, technical sections can be mastered with confidence and obstacles such as roots and thick branches can be overcome by applying targeted pedal pressure with the Extended Boost.

Sporty and economical
Sporty riding on a hybrid eBike or eMTB: The Tour+ mode of the Performance Line CX allows riders to focus purely on riding. It eliminates the need to manually switch between riding modes and saves energy by increasing rider performance. This provides a natural riding sensation in every situation, even during extended rides.

Smart Walk Assistance
Even on the steepest of trails when riding is no longer an option, the eBike can be pushed more easily using Walk Assist: Simply press and hold the minus button, move the eBike and you will already feel the support. The LED Remote and Kiox 300 also provide you with a visual "guide" to facilitate operation. Walk Assist particularly helps you when eMTB riding uphill in difficult terrain or on stairs.

Wireless speed sensor
In addition to the wired solution, the smart system features an internal speed sensor, which is located in the drive unit. The spoke magnet is now attached directly to the wheel, resulting in a cleaner eBike look.

The riding modes
With the help of the riding modes, the support of the eBike motor can be easily adjusted via the control unit/display. All modes for optimal support in every situation can be found here.
Off | Eco | Tour** | Tour+** | eMTB* | Sport* | Turbo |
---|---|---|---|---|---|---|
No support, all display functions can be called up. | Low support with maximum efficiency for highest range. | Consistent support for longer rides. | Continuous support for energy-saving rides. | Dynamic support for a natural feel and optimal control when eMTB riding. | Powerful support for all types of riding. | Maximum support for challenging rides. |
*In eMTB mode, the assistance level varies between Tour and Turbo riding modes.
**In Tour+ mode, the assistance level varies between Eco and Turbo riding modes.
All available riding modes can be freely combined in the smart system.
The bike manufacturer can activate up to four modes (in addition to the Off mode) and thus perfectly match them to the eBiker (unless changes have been excluded by the bike manufacturer).
With the help of the individual riding modes, you can configure the Eco, Tour, Sport and Turbo modes according to your needs via the eBike Flow app. You can adjust the support, the dynamics, the torque and the maximum speed.
Smart features

Individual riding modes
Adapt the riding mode to your needs with the eBike Flow app: You can fine-tune the Eco, Tour, Sport and Turbo riding modes to give you either more support or 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 the Bluetooth connection, your eBike is less attractive to thieves.

The Performance Line CX - for the Bosch eBike System 2

More torque
Increased to 85 Nm, the torque has a noticeable effect on riding behavior. This results in faster acceleration, particularly at low cadences, and makes uphill starts much easier. The eMTB rider has more power available directly in difficult conditions.

Perfect control
The advanced eMTB mode ensures even better control on the trail, without having to switch riding modes. The motor responds much more sensitively to the rider's effort, especially in low gears, enabling an extremely sensitive start.

Extended Boost
Extended Boost is the unrivalled function for conquering exposed roots, steps and stones with ease, even uphill. The eMTB will respond with agility and ease to even the most demanding trails.

Sporting efficiency
Choosing a sporty riding style can take you further with Tour+ mode. The riding mode rewards your slightly higher effort with energy efficiency: If you pedal harder, the drive offers you greater support. If, on the other hand, the ride is fairly easy, you'll receive less assistance. This means that the battery is discharged more slowly resulting in more range.

Natural riding sensation
The powerful 32-bit processor enables sensor signals to be processed at high speeds. Performance can be controlled precisely, offering eMTB riders the best possible support in all riding situations.

Thermal stability
The drive unit is extremely efficient and, thanks to the completely maintenance-free 16-pin BLDC electric motor featuring the latest bar winding, it is characterised by great thermal stability. This ensures constant performance even under continuous load.

New Ideal comfort every time
E-Live Valve for the Performance Line CX from FOX with Bosch eBike Systems offers eMountain bikers electronically controllable suspension designed for maximum off-road comfort and fun. FOX E-Live Valve can be easily controlled via the Kiox on-board computer and is powered via the Bosch battery. Using a sophisticated system of sensors, the FOX E-Live Valve system determines the conditions of the terrain 1,000 times per second and adjusts the suspension fork and rear shock accordingly within fractions of a second.
