⚡ Torque

The Touroll J1 ST is equipped with a rear hub-drive motor that delivers 45 Nm of torque. In practical terms, this torque rating reflects the twisting force the motor applies directly to the rear wheel, giving you a gentle boost as you pedal. Because the drive unit is housed in the wheel hub, you’ll experience a quiet, low-maintenance setup that doesn’t interfere with the bike’s chain or gears.

Compared with the category average of 93 Nm, the J1 ST’s 45 Nm output is modest—roughly half the typical torque you’ll find on many trekking-style e-bikes. This means the J1 ST excels at steady cruising on flat roads or mild urban inclines, but you may notice slower acceleration from a standstill and extra effort required on steeper hills. Riders who routinely tackle grades above 8–10% will feel the difference most acutely.

This torque characteristic matters most for commuters and leisure cyclists who value a smooth, unobtrusive boost over raw climbing power. If your daily routes are relatively flat or you carry minimal cargo, the J1 ST’s hub-drive motor should meet your needs with reliable, near-silent assistance. However, riders seeking quick launch response or frequent hill climbs might prefer a higher-torque system.
