The new Bosch Performance CX Race is a limited edition motor. Only a few consumer ebike models will get it. The motor is developed for the ebike racers. It’s been that way for long in other bike sports, or even for cars. A lot of the development happens in the racing teams. The the upgrades reach the consumer market a while later. Check out Rob’s video, or keep reading below for a few highlights.
Same power, but for longer
The new Performance CX Race has the same 85Nm torque as the Performance CX. But it amplifies the rider input more, up from 340 to 400%. And the weight is reduced from about 2.9 to 2.75 kg.
The Performance CX Race is still a legal motor with 250W nominal power and the 25km/h cut-off speed. But Bosch have maximized the time we get full motor power. When racing, there is no time to wait for the motor to activate carefully and smoothly. Therefore, the motor activates quickly and with a lot of power. And it remains powerful untill you pedal over 120 rpm. And it’s maximum motor power all the way up tp 25km/h. Accessing the motor power is more important than having a motor that ramps down comfortably when approaching cut-off speed. Also, it’s got a bit of motor overrun, so it continues to push if you have to stop pedaling briefly to avoid a pedal strike.
