Since its launch in June 2019, Bosch have further refined the Performance Line CX motor’s firmware. The new firmware delivers an extra 10 Nm torque Head over to our big motor group test to find out how the Bosch fared against the competition from Brose, Shimano and more. We also compared the Bosch Performance Line CX, updated with the new software against other popular motors on the market. We’ve been testing the update for several weeks, on different bikes and in different conditions, and compared it against the old software. As a result, the characteristics of each motor, from the Cargo Line all the way to the classic Performance CX, should be more differentiated and provide optimised ride dynamics for where they are used. According to the manufacturer, the latest update allows them to adapt the behaviour of each motor more specifically to its respective area of application. One year after launching their new Performance Line CX 2020, Bosch have released a new software update for all of their current ebike motors.
