Brose CB (1.2E)

Charlie McCormick

Brose produced a special motor just for Specialized’s entry level eBikes (Specialized calls it the Turbo 1.2E) It is geared toward efficiency for excellent range, while still providing plenty of torque at low rpms so fully loaded commuters can flatten their hills out, applied with the Brose signature natural feeling smoothness.

An array of internal sensors means the motor intuitively reacts to the force of your pedaling, so the harder you pedal, the more power it delivers. The internal carbon fiber belt drive design keeps motor noise and vibration to a minimum for the smoothest ride possible.

The motor peaks at 50nm and 420 watts, on par wit both the Shimano Steps 6100 and the Bosch Active line. It gives more power at lower pedal rpms (20-70) than the Bosch, so the Brose feels more supportive in city stop and starts. Specialized has there's an app (MIssion Control) where you can tune motor performance via bluetooth on your smartphone. The “Smart Control” feature allows you to algorithmically manage your power from a set trip time or distance. 

Raw power is exhilarating and addictive - but full power all the time can also meaning depleting your battery very quickly, so judicious use of power is something eBikers value more over time - that is where the ability of the Brose motor to be fully custom tuned by the manufacturer via firmware (or in a more limited way with the bluetooth app), comes into play, a feature that Bosch does not have yet.
