Power meets control: Bosch sets new standards in eMTB with latest Performance Line CX
More dynamic, more agile and quieter than ever
- The next evolutionary step of the Performance Line CX combines power, dynamics, efficiency and range in an ideal ratio
- Even better riding dynamics and agility thanks to optimised sensor technology
- Reduced noise and lower weight
- Sporty ecosystem: Bosch eBike ABS Pro, Purion 400 display and PowerTube 600 and PowerTube 800 batteries complement the new drive unit
Bosch eBike Systems introduces the latest generation of Performance Line CX motors, bringing more dynamics and more agility on mountainous trails. With the latest motor, power meets control. In conjunction with the Bosch eBike ABS Pro, the Purion 400 display, powerful PowerTube batteries, Bosch presents a comprehensive sporty ecosystem for the ultimate eMountain bike experience.
The ideal balance of power, efficiency and range
For eMountain bikers, it is not just performance data that is crucial, but the precise fine-tuning of the motor. This determines the flow factor on the trail. “With 85 Newton metres of torque, a maximum power of 600 watts and up to 340 percent support, the new Performance Line CX delivers the ideal balance of power, dynamics, efficiency and range.” says Claus Fleischer, CEO of Bosch eBike Systems. “Whether for sensitive starts on steep trails or powerful, perfectly controlled exits from corners: With its precise, sensitive response behaviour, our new drive unit allows sporty eBikers to experience unique riding dynamics for the perfect eMTB experience.” A variety of different riding modes are available for Performance Line CX, which can be selected and customised in the eBike Flow app.

Sensitive sensor technology and dynamics on a new level
The power of the new Performance Line CX is precisely matched to the relevant riding manoeuvre and accurately follows the pedal input. This is made possible by re-engineered sensor technology. Several high-performance sensors precisely measure the pedal input – more than 1,000 times per second. The many sensors used include a high-resolution cadence sensor and precise torque measurement technology. Inertial sensors (IMU) also measure acceleration and rotation speeds in six dimensions, recognising inclination and tilt angles as well as vibrations. This means that the eMTB “knows” how steep the ascent is and whether eBikers are on a forest path or a root-covered trail. The drive unit is highly sensitive, responding to changes in acceleration, rider’s pedal power and current speed. Thanks to the newly interpreted sensor signals, eBikers always receive the right motor power – sensitive, controlled and immediate, or gentle, restrained and reliable for long rides. The Performance Line CX is an all-rounder.
The sound of the trail and nothing else
Many cyclists want a motor that is as quiet as possible, combined with a natural riding experience. Bosch has optimised the gearbox of the new Performance Line CX with a view to achieving a good balance between power, efficiency and noise levels. When riding downhill, the external drivetrain (chain, chainring, cassette) is decoupled from the internal drivetrain (freewheel, gearbox, motor). This further reduces the mechanical noise generated by comparable drive units, and the full focus remains on the trail and nature.
The weight of the Performance Line CX has also been reduced by around 100 grams compared to the previous version. The drive unit is extremely robust, with a magnesium housing that withstands the toughest conditions. A black powder coating protects against stone chips and damage as well as corrosion.
The motor that defined eMountain biking: Performance Line CX
If there is one eBike motor that is synonymous with eMountain biking, it’s the Bosch Performance Line CX. Specially developed for eMTBs, it has established itself as a permanent fixture in the mountain bike scene since its launch almost ten years ago (2015) and has defined performance eBiking as a field in its own right. Since then, the drive unit has undergone several stages of evolution and continues to set standards in terms of riding experience and motor characteristics. The pioneering, progressive/dynamic eMTB mode and many other technical developments complement the Performance Line CX, making the riding experience on the eMountain bike unique.
Full support right up to the summit: useful features for steep sections
With the new hill start assist riders can tackle challenging uphill terrain in a controlled manner and with full traction. Thanks to the sensors, the eMTB knows how steep the slope is and provides optimum support. A new walk assistance feature allows the drive unit to adapt to walking speed whilst pushing the bike.
Maximum braking performance: the new Bosch eBike ABS Pro
On the downhill trail, demanding mountain bikers want to focus more on their riding line and less on their braking. The new Bosch eBike ABS Pro increases riding stability by allowing late and powerful braking without the front wheel slipping. During development, Bosch incorporated experience and technology from eMTB racing, resulting in two ABS Pro modes: ABS Trail Pro for performance-led mountain bikers and ABS Race for enduro racers. The new eBike ABS Pro achieves the optimum balance between riding stability and maximum braking performance.
Perfect eMTB display: introducing the Purion 400
The new Purion 400 display is part of the updated ecosystem and complements the Performance Line CX with a minimalist look adapted for eMTBs. Optimally protected in the handlebar triangle, the transmissive 1.6-inch display offers a good overview of the essential riding and fitness data such as speed, range, power and total distance.
Battery innovation for even longer rides: PowerTube 600 and 800
Energy reserves play a decisive role on demanding, multi-day rides covering many metres of elevation gain. For this purpose, Bosch has developed the PowerTube 800 – the largest PowerTube battery in the smart system to date, perfectly matched to the new Performance Line CX. At around 205 Wh/kg, the battery has the highest energy density in the portfolio. The portfolio is complemented by the new PowerTube 600.
Bosch uses battery cells with an optimised energy density and a newly developed aluminium housing for both batteries. Integrated into the frame tube, they blend seamlessly into the eBike design. Thanks to their identical length, they can be easily removed and replaced by the eBike manufacturer. They are also DualBattery-capable. eMTB enthusiasts can use two PowerTube 800s to achieve a total capacity of 1,600 Wh to master even the most challenging route sections, and achieve many metres of elevation gain even when there is no possibility of intermediate charging. Alternatively, you can use the drinking bottle- sized range extender PowerMore 250 as an additional battery.
Focus on sustainability in production
Bosch aims to continuously improve the sustainability of all eBike systems throughout the entire product life cycle. To produce the Performance Line CX and the PowerTube 600 and PowerTube 800 batteries, Bosch eBike Systems uses partially recycled materials, for the first time seeing the largest plastic part being the drive unit as well as in the battery holder and the battery housing1. Furthermore, the amount of material used for the rechargeable batteries has been reduced2 and the black colour coating has been omitted from the PowerTube 600 and PowerTube 800. Bosch eBike Systems is focussing on purchasing components that were produced using electricity from renewable sources in a further milestone for the brand. This applies to the aluminium of the PowerTube 600 and the PowerTube 800 as well as to the housing of the Performance Line CX.
