Performance Line CX: the most sporty Bosch motor for eMTBs

The Performance Line CX offers a unique eMTB experience: Compact, lightweight and with more power, it combines high-quality materials, an extremely powerful drive and high-end sensors. This brings eMountain biking on the trail to a whole new level. From model year 2021 with a torque of up to 85 Nm, features in the motor control and a further development of eMTB mode - all as a software update. For a thrilling riding experience: more natural, intuitive and powerful and an absolute benchmark in its class.

The Tour+ riding mode for the Performance Line CX with derailleur system (from model year 2020) and eMTB mode will be available from summer 2021.

Contact your specialist dealer directly to find out whether your eBike can be retrofitted with Tour+ mode.

More torque

More powerful than ever: Increased to 85 Nm, the torque has a noticeable effect on riding behaviour. It accelerates faster, particularly at low cadences, and makes uphill starts much easier. The eMountain biker has more power available for whenever it's needed.

Extended Boost

Impressive performance on the trail: Extended Boost is the unrivalled function for negotiating exposed roots, steps and stones with ease, even uphill. This function enables you to manoeuvre with greater agility and ease on even the most technically demanding trails.

Perfect control

Ready for every challenge: 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.

New Sporting efficiency

Choosing a sporty riding style can take you further with Tour+ mode. The riding mode rewards your slightly increased power input with greater energy efficiency: The harder you pedal, the more the drive will support you. If, on the other hand, the going is fairly easy, you'll receive less assistance. This means that the battery is discharged more slowly. This will extend your rides, as well as your riding enjoyment.

Natural riding dynamism

Perfectly controlled support: The powerful 32-bit processor enables sensor signals to be processed at high speeds. Performance can be controlled precisely, offering eMountain bikers the best possible support in all riding situations.

Thermal stability

For extreme loads: 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 Sporty riding on a trekking bike or eMTB: The Tour+ mode of the Bosch Performance Line CX always focuses on riding enjoyment. It eliminates the need to switch between support modes, so you can focus entirely on the eBiking. Tour+ mode requires you to pedal harder on flat tracks than Tour mode - thus saving power and extending your boundaries for even more riding enjoyment!
Whether off-road or on asphalt, Tour+ mode is always the perfect choice. That's because it constantly adapts to you. Sensors on the motor measure important riding data more than 1,000 times per second, enabling Tour+ mode to determine optimum support for you. It delivers the additional power so sensitively that you not only experience a natural riding sensation, but also enjoy a longer range by applying more power.

A riding experience that sets the benchmark: From model year 2021, the Performance Line CX ensures even more riding enjoyment on the trail - with further developed software and a maximum torque of 85 Nm. The increased torque ensures greater performance, supporting you with even more power, especially in low cadences. In eMTB and Turbo mode, this leads to significantly faster acceleration and makes hill starts much easier. Thanks to a broader cadence range, unpredictable riding situations can be mastered even more effectively - for example in the case of late gear shifting or accelerating out of tight corners. Riding remains smooth and free from jolts, even when out of the saddle or in Turbo mode.

The progressive riding mode for every occasion: Advanced eMTB mode ensures eMountain bikers are well-prepared for whatever riding situation the trail may have in store. Sensor and motor control functions give eMountain bikers a much wider range of dynamic and natural support. Riders continue to benefit from the proven technology of eMTB mode: Depending on pedal pressure, progressive motor support adapts perfectly to the riding situation. The improved adjustment of eMTB mode ensures optimum traction control in all gears and enables organic handling (AKA 'power on demand'). Start-up behaviour is much finer and more sensitive - especially in low gears. Due to the increased torque, the drive unit supports an even wider cadence range.

Extended Boost is the unrivalled function for negotiating exposed roots, steps and stones on the trail with ease, even uphill. The eMTB can be maneuvered with much greater agility and ease on technical sections. The unique dynamism means that obstacles can be overcome with ease by applying the right amount of pressure to the pedal. The pedals rarely, if ever, jam. The new, innovative function in eMTB mode can be controlled to optimum effect in all riding situations. If the front wheel is already on the step, a slight pedal pressure is all it takes to give the decisive "kick". This takes pedal management to a whole new level.

The software update is available from specialist retailers and is available for all eBikes with the Performance Line CX from model year 2020 onwards. eBike models from model year 2021 onwards are available with the update from specialist bike dealers.
