A new era for electric mountain bike riders
Performance Line CX provides a unique eMTB experience. Compact, lightweight and with more power, it combines high-quality materials with an enormously powerful drive and sophisticated sensors. It adds a whole new dimension to eMTB riding on the trail. With the model year 2021 software update, it offers torque up to 85 Nm, new motor control features and an enhanced eMTB mode. For an exciting riding experience: natural, intuitive, powerful and an absolute benchmark in its class.
Highlights
New More torque
More powerful than ever: Increased to 85 Nm, the torque has a noticeable effect on riding behavior. It accelerates faster, particularly at low cadences, and makes uphill starts much easier. The eMTB rider has more power available for whenever it's needed.
New Extended Boost
Impressive performance on the trail: Extended Boost is a unique function that helps you ride smoothly over roots, steps and stones, even when going uphill. With this function you can maneuver with greater ease and agility on challenging trails.
New 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.
Maximum agility
Extraordinary sensitivity: Thanks to the multi-sensor concept that takes more than 1,000 measurements per second, the Drive Unit is characterized by an extremely sensitive response.
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 eMTB riders 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 characterized by great thermal stability. This ensures constant performance even under continuous load.
Performance upgrade and new features
New A riding experience that sets new standards: As of model year 2021, Performance Line CX provides even greater riding enjoyment on the trail thanks to enhanced software and a maximum torque of 85 Nm. The increased torque delivers a performance boost for even more powerful support, especially at low cadences. This provides noticeably faster acceleration in eMTB and Turbo mode and makes starting off on steep sections much easier. The wider cadence range makes it easier to handle unforeseeable riding situations – as can happen in the case of late gear shifting or when accelerating out of a tight corner. The ride remains smooth and controlled when out of the saddle and in Turbo mode.
Next-level eMTB mode
New The progressive riding mode for every occasion: Advanced eMTB mode ensures eMTB riders are well-prepared for whatever riding situation the trail may have in store. New sensor and motor control functions give eMTB riders 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 behavior 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
New 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.
Retrofitting and availability
The software update is available from specialist retailers and is available for all eBikes with the Performance Line CX from model year 2020 onwards. New eBike models from model year 2021 onwards are available with the update from specialist bike dealers.

Frequently asked questions about the Perfomance Line CX
eBikes with the Drive Unit Performance Line Speed or Cargo Speed cannot be retrofitted, but new models with the 85 Nm update will be available from specialist dealers from fall 2020. This is due to the fact that the Speed version with the new software must undergo homologation.
The 85 Nm upgrade is available from specialist dealers as a software update from now on.
The Performance Line CX from MY2020 onwards is based on a completely new platform with new electronics, new electric motor and new gearbox. The software of the older model (up to MY2019) therefore also differs from the software of the new model (from MY2020 onwards) and is not compatible with the MY2021 software update.
