NEW BOSCH PERFORMANCE LINE CX
Bosch’s flagship power plant now has more range and power with less noise.
Press release
You’re going to be seeing a lot of new bikes with the new Performance Line CX power plant from Bosch, so here’s some info about the updated e-bike system from the German company. The top line numbers for Bosch’s updated Performance Line CX power plant are 85NM maximum torque, 600W maximum power and up to 340 per cent support.
The new motor system also features new larger capacity battery options at reduced weight, decoupled drive unit for less drag, ABS braking (TRP and Magura brakes) for improved control, and a new hill start mode that holds the bike on steep pitches.
Sensitive sensor technology and dynamics
The power of the new Performance Line CX unfolds dynamically and is precisely matched to rider demands. This is made possible by re-engineered sensor technology. Several high-performance sensors precisely measure the pedal input – more than 1000 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, and recognise inclination and tilt angles as well as vibrations.
This means that the eMTB can sense the grade and roughness of terrain. The drive unit responds highly sensitively to changes in acceleration, rider’s pedal power and speed. Thanks to the newly interpreted sensor signals, riders always receive the right amount of motor power.
The sound of the trail and nothing else
Bosch has optimised the gearbox of the new Performance Line CX to balance power delivery, efficiency and noise levels. When riding downhill, the external drivetrain (chain, chainring, cassette) is decoupled from the internal drivetrain (freewheel, gearbox, motor) reducing mechanical noise.
The weight of the Performance Line CX has also been reduced by about 100g compared to the previous version. The drive unit is extremely robust. Its magnesium housing withstands the toughest conditions. A black powder coating protects against stone chips and damage as well as corrosion.
Bosch eBike ABS Pro
Bosch eBike ABS Pro increases riding stability by allowing late and powerful braking without front wheel wash. During development, Bosch incorporated experience and technology from eMTB racing. This has resulted in two ABS Pro modes: ABS Trail Pro and ABS Race for enduro racers. The new eBike ABS Pro achieves the optimum balance between riding stability and maximum braking performance.
Hill start and walk mode
If e-Bikers have to stop on challenging uphill terrain, it is important to get out of this situation in a controlled manner. With the new hill start assist you can ride off in relaxed manner and with full traction. Thanks to the sensors, the eMTB knows how steep the slope is and provides optimum support. Also new: With the walk assistance feature, the drive unit adapts the pushing speed to the walking speed.
New Purion 400 display
With a minimalist look and safely tucked behind the handlebar, the Purion 400’s new 4cm display offers a good overview of the essential riding and fitness data such as speed, range, power and total distance.
PowerTube 600 and 800 batteries
Bosch’s new PowerTube 800 is the largest PowerTube battery in the smart system to date. At about 205 Wh/kg, the PowerTube 800 has the highest energy density in the Bosch battery line up. The PowerTube 600 is the lighter alternative for riders who want less weight and need less range.
Bosch uses battery cells with an optimised energy density and a newly developed aluminium housing for both batteries. Thanks to their identical length, they can be easily removed and replaced – if provided for by the eBike manufacturer. They are also DualBattery-capable and can be combined. eMTB enthusiasts, for example, can use two PowerTube 800s to achieve a total capacity of 1600Wh.
Alternatively, you can use the water-bottle-sized range extender PowerMore 250 as an additional battery.
