Bosch Performance CX Review

With 75 Nm of torque, the CX pulls strongly and doesn’t seem to get affected by inconsistent pedalling. You can feel the motor engaging, but not to the point that it will bother you. At speeds above 25 km/h the internal gearbox creates a substantial drag that holds you back. There are four support levels with a range between 50 and 300%. The new eMTB mode replaces the previous Sport mode, and its progressive power delivery (120-300% depending on the pressure on the pedals) eliminates the need for a constant change of support levels. This allows you to finely modulate the motor during starts. Unfortunately, the motor releases huge amounts of support even with a more moderate pedal pressure, making it difficult to save battery in the eMTB mode. The Bosch’s dimensions are also rather large. This may restrict the manufacturer’s freedom in designing geometries and frames and has already resulted in some daring frame designs.

From this year Bosh offers the integrated PowerTube battery with a 500 Wh capacity, providing many 2018 bike models with a facelift replacing the classic external PowerPack battery. There is a choice of three displays, where the big Nyon model provides you with a huge amount of information and therefore appeals mainly to commuters and trekkers, while the compact Purion is the optimal choice for eMTBers.
