The Performance Line CX and eMTB mode from Bosch enable eMountain bikes to master challenging mountain passes and ambitious mountain trails more easily. For Model Year 2019, Bosch eBike Systems has two additional new features in store for its powerful drive: The more powerful walk assistance enables sharp increases to be mastered easier, and a new application optimises power transmission - even on eMountain bikes with short cranks.

Improved walk assistance for steep terrain

If neither motor power nor riding technique allows them to keep going, eMountain bikers need walk assistance that offers significant support - especially on steep slopes. The MY2019 update enables eMountain bikes to be manoeuvred even more efficiently and evenly uphill: Thanks to a gradient sensor, the walk assistance automatically adapts to the slope and so the target speed is reached much quicker. The optimised walk assistance also makes it easier to make progress, even if the wheel briefly encounters resistance or an obstacle.

New application for short cranks

Things can sometimes get difficult on technical uphill sections when negotiating rocks and roots. The pedals can ground which could lead to a fall. That's why more and more riders choose shorter cranks and thus more ground clearance. These are also ideal for smaller riders. However, short cranks change the power transmission of the eMountain bike and thus the maximum support from the motor, also influencing the motor characteristics in eMTB mode. The new software has allowed Bosch eBike Systems to adapt the progression curve in eMTB mode and increase support in ‘Tour’ mode. This ensures maximum power on uphill sections. The new software for cranks of 165 millimetres and shorter can be installed by dealers from MY2019 onwards.

Both eMTB innovations will be introduced for the 2019 Model Year and can be retrofitted for all eBike models with the Performance Line CX from the 2016 model year onwards.
