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.

About Bosch eBike Systems

A new generation of bikes is taking town and country by storm and is already a part of everyday life. eBikes are a modern means of transport for modern people: people in a hurry and people who prefer to take it easy, the fit and the comfort lovers, commuters and pleasure cyclists and, of course, young and old. The tailwind of technology-leading eBikes made by what are already more than 70 leading brands in Europe is powered by components that Bosch is developing to perfection. The Bosch portfolio ranges from the highly efficient drive unit (motor and gearbox) and high-quality batteries to a smart on-board and cycle computer that can be used intuitively. Perfect coordination of components holds the key to typical Bosch performance in terms of both comfort and efficiency.
Like other Bosch products, the eBike systems benefit from the Bosch Group’s technology and production know-how. From conception and engineering to manufacturing, marketing and after-sales service, Bosch eBike Systems constantly set new standards for the eBike industry. The Bosch Group’s experience in the areas of electric motors, sensor technology, displays and lithium-ion batteries ensures that Bosch eBike systems use technology that is invented for life and that eBike users have their fun.
