SL Motor
Motor Power & Torque
You can measure the power of a motor in the maximum watts it can produce. A motor that produces more watts will make it easier for you to maintain a certain speed while riding. All Specialized motors offer optimal support over a broad range of pedaling cadences – even beyond 100 rpm. This helps provide a more natural feel.
- The original SL motor provides 240w of nominal/peak output and 35 Nm of torque
- The SL 1.2 motor provides 250w nominal power with 320w of peak output and 50 Nm of torque
This is equivalent to about 180% of rider power or 2 x you.
Efficiency
To get maximum range, riders should pedal smoothly at cadences of 75 rpm and higher. This is also the most knee/leg-friendly way of pedaling.
Warranty
All motors are covered under warranty for 2 years from date of purchase.
