⚡ Torque

The Touroll S2 and S2 Pro are equipped with a rear hub-drive motor that delivers 57 Newton-meters of torque. In plain terms, torque is the twisting force that the motor applies to the wheel axle—higher numbers generally translate to stronger hill-climbing ability and more immediate acceleration off the line. At 57 Nm, the Touroll’s motor sits well below the category average of 93 Nm, meaning it won’t offer quite the same shove as many mid-drive or higher-torque hub motors when you push the throttle at a standstill or tackle steep inclines.

For the everyday rider, 57 Nm is still sufficient for moderate grades and urban cruising. Commuters on relatively flat routes will find the S2 smooth and responsive, with enough pull to get up to speed quickly in traffic. However, if your route features sustained hills or if you’re frequently hauling heavy cargo—think loaded panniers or a passenger—the reduced torque output may translate to slower climbs and more reliance on pedal assist. You may need to stand on the pedals or shift to a lower gear sooner than you would on a higher-torque e-bike.

This torque profile particularly matters if you prioritize off-road riding or have a heavier build. Riders who regularly tackle steep gravel paths or who weigh over 200 lbs should be aware that the S2’s 57 Nm won’t match the brisk hill-hiking feel of a 90 Nm-plus motor. On the other hand, those seeking a lighter, more affordable folding fat-tire bike for mostly flat terrain will appreciate the S2’s balanced performance, compact design, and the ample—but not overwhelming—torque it provides.
