Brose S (1.3)

Charlie McCormick

The S motor line is at the very front of the big dog pack - dramatically peppier than most competing systems, with 15% more power than the already strong Brose T. Pushing 90nm of torque and 550 (560 for the Mag version) peak watts, and applied with the signature Brose smooth/natural feeling with low noise/vibration. Brose uses the same motor for leisure, sporty and off road - the tuning is different to suit each experience.

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.

In terms of raw peak power, the Brose S is between the Bosch Performance (street) and top dog Bosch Performance CX (off road) motors - but that is only one part of the ebike performance equation. Torque (or the climbing grunt of a motor) is 20% higher with the Brose S over the CX. Total bike weight is a major factor (deriving from both battery, motor and frame supports), which is where the Brose S starts to really edge out the Bosch,

Brose motors also kick in at lower cadence - you get more power at lower pedal RPMs than the Bosch, so the Brose feels more powerful off the line. There is also more assistance at the higher RPMs so you don’t feel the motor dropping off when you are pedaling all out.

Specialized uses the S motor in the Levo, Como and Vado bikes, but calls it "Turbo 1.3" and there's an app that you can tune motor performance via bluetooth on your smartphone. If you have the latest TCD-W display on a Vado/Como you can connect to the Mission Control 2.0 app.  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. The app allows you to custom tune the assistance levels, or use “Smart Control” to algorithmically budget your power for you based on trip time or distance.
