Bosch is currently launching the new generation of its "Performance Line CX" MTB motor line. The hard facts are provided by the new battery, which, with its 800 watt hours, has significantly more power. There is also a lighter version of this battery with 600 watt hours, which is compatible in design with its more powerful brother. This means that it can be easily replaced. With around 205 watt hours per kilogram, the battery has once again improved significantly in terms of energy density. Speaking of weight: the CX motor has been slimmed down in the latest generation and is 100 grams lighter than its predecessor.

More sensitivity thanks to additional sensors 

The real innovations in the CX motor are not in the naked performance data, but in the soft factors. This is due to the additional sensors that have been integrated into the drive unit. These include cadence or inertial sensors, which measure acceleration and rotation rates in six dimensions and also record inclination and tilt angles as well as vibrations. The sensors deliver over 1000 measured values per second to the control software, resulting in a significantly more sensitive drive that comes a lot closer to "natural" cycling.

Bosch is using the new measurement data to launch a new feature: hill start assist. The drive unit recognizes the steepness of the slope, keeps the rider in position with a measured application of force and then accelerates smoothly but powerfully as soon as pressure is applied to the pedals. The hill start assist is a new development from Bosch, which will be one of the central features of an electric drive in the future. The pushing aid has also been revised: the drive now adapts the power supplied to the walking speed.

Fighting noise pollution

Another soft factor of an electric motor is noise emissions. The new CX motor is audibly quieter. Above all, however, the familiar rattling noise that many Bosch mountain bikers are familiar with is gone. One of the reasons for this is that the external drivetrain (chain, chainring, cassette) is decoupled from the internal drivetrain (freewheel, gearbox, motor) when riding downhill.

The new CX motor is already rolling off the assembly lines, and the first manufacturers are currently presenting their new e-mountainbikes with the significantly improved drive unit.

Together with the new CX motor, Bosch has also presented its new ABS technology for tough trail use. This is an integral part of the new Bosch motor generation. Further information: ride-mtb.com/news/now-comes-abs-for-tough-trail-use
