⚡ Torque

The Touroll B2 City Step-Thru is equipped with a rear hub-drive motor delivering 50 Nm of torque, noticeably below the 93 Nm average found in this category. Torque is the force that propels you forward when you start pedaling, accelerate from a stop, or tackle inclines. At 50 Nm, you’ll experience more modest off-the-line punch and slower hill-climbing than bikes with higher-torque mid-drive systems or more powerful hub motors.

In practical terms, a 50 Nm torque rating means the B2 will perform smoothly on flat city streets and light rolling terrain, but you may need to put in extra effort on steeper grades or when carrying heavier loads. Compared to bikes pushing close to 100 Nm, it accelerates less aggressively and can feel more leisurely under load. Riders who often encounter long, steep climbs or who regularly haul cargo or passengers will feel the difference most, especially on gradients steeper than 5–7 percent.

For urban commuters and casual riders whose routes stick mainly to flats or mild hills, the Touroll B2’s 50 Nm hub motor still offers reliable, quiet assistance. Its lower-torque setup helps keep weight and mechanical complexity down, making it a good fit if you prioritize ease of use, straightforward maintenance, and a relaxed ride over raw climbing power.
