Stuttgart/Reutlingen – Starting in summer 2020 eMountain bikers can ride trails with even more dynamism, agility and intuitive handling: Developed for athletic applications, the Performance Line CX from Bosch eBike Systems is getting a comprehensive software update with features that will make a significant difference when trail riding. Extra power comes from an increased maximum torque of up to 85 Nm. Extended Boost increases trail performance on difficult sections, while an advanced eMTB mode provides noticeably more sensitive start-up behaviour on rough surfaces. Software and sensors perfectly combine to optimise the output of the powerful and highly efficient CX drive unit – giving eMountain bikers an unrivalled riding sensation.

Master challenging riding situations

As the benchmark in the eMTB sector, the Performance Line CX typifies pure trail riding enjoyment. This includes the ability to accelerate quickly and powerfully even at low cadences, as well as being able to perform standing starts on the steepest of terrains. These characteristics are getting better still with maximum torque increased to 85 Nm in both eMTB and Turbo modes. The performance upgrade offers full power over a broad cadence range. "This enables unpredictable riding situations to be mastered even more effectively," explains Claus Fleischer, CEO of Bosch eBike Systems. "Delayed gear shifting, for example, is better compensated and acceleration out of tight turns is much more powerful and dynamic." This also means eMountain bikers will have more power readily available in particularly technical sections. In addition, the riding experience feels absolutely natural and free from jolts, even when standing on the pedals or in Turbo mode.

Feel the Flow over a wide range of cadences

In eMTB mode, motor support progressively adapts to the eBiker's individual riding style, depending on the pedal pressure. The software update includes refinements to eMTB mode. New sensor and motor control functions provide even more dynamic and natural support over an extended range of cadences. Claus Fleischer explains: "The retuned eMTB mode gives a further noticeable improvement of the bike's handling on the trails. There is greater traction control and start-up behaviour is much finer and more sensitive, especially in low gears." Consistent with the increased torque, the drive unit supports a wider cadence range and eMTB mode delivers the right power at any given moment – for that ultimate flow.

Negotiate obstacles smoothly

Extended Boost ensures improved performance on challenging sections of trails. This helps eMountain bikers to negotiate exposed roots, steps and stones, even uphill: With appropriate pressure applied to the pedal, the system responds in a fraction of a second and provides the decisive thrust for negotiating an obstacle. This enables the eMTB to be manoeuvred with agility and ease through technically intricate sections of trail. Extended Boost eases pedal management and ensures that the pedals rarely, if ever, jam. The function comes into play in eMTB mode and can be controlled with ease in all riding situations.

Get greater riding enjoyment at all times

Claus Fleischer explains why the Performance Line CX is the ideal drive system for eMountain bikers: "The drive offers maximum thermal stability and extremely high efficiency. Software and sensors perfectly combine to eliminate the often complicated customisation of software characteristic curves. Regular updates combined with our award-winning service enable eMountain bikers to experience a new dimension in riding enjoyment at all times."

The software update will be installable by specialist retailers starting in summer 2020 and is available for all eBikes fitted with Performance Line CX from model year 2020 onwards. Maximum torque is also being increased to 85 Nm for the Cargo Line, Cargo Line Speed and Performance Line Speed drive systems.
