Performance Line CX – The highest performance eBike drive – Bosch eBike Systems

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. Since model year 2021, it offers torque up to 85 Nm, motor control features and an enhanced eMTB mode. For an exciting riding experience: natural, intuitive, powerful and an absolute benchmark in its class.

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.

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.

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 Sporty 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, riding is fairly easy, you'll receive less assistance. This means that the battery is discharged more slowly.

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.

New Sporty riding on an adventure bike or eMTB: the Tour+ riding mode of the Bosch Performance Line CX eliminates the need to switch between support modes, so you can focus entirely on your ride. With the Tour+ mode, you pedal harder on flat sections than with the Tour mode for a more sporty ride. This saves battery power and extends your radius.
Trail or asphalt – the Tour+ mode is constantly adapting to you. Sensors on the motor measure important riding data more than 1,000 times per second resulting in a natural riding sensation and longer range.

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. 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 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.
