⚡ Nominal Power

The Touroll B2 City Step-Thru Electric Bike is equipped with a 250 W nominal hub-drive rear motor, which is the standard power level for many European-market e-bikes. In a category where the average nominal motor rating sits at 744 W, the B2’s motor delivers barely one-third of that output. Riders will notice that its peak assistance is calibrated more for steady urban cruising than for rapid acceleration or heavy-duty hauling.

Because its motor delivers 250 W rather than the typical 744 W, the B2 offers gentler throttle response and slightly reduced hill-climbing capability. On flat city streets, it will keep pace with traffic and conserve battery energy, often translating into longer range per charge. However, on steeper slopes or when carrying heavy loads, a bike with a higher-power motor will accelerate faster and maintain speed with less effort from the rider.

This level of motor power matters most to urban commuters and leisure riders who prioritize light weight, low maintenance, and efficiency on mostly level routes. If your daily rides involve steep inclines, frequent highway stretches, or carrying passengers and cargo, you may benefit from models in the 700–800 W range or above. For short to medium-distance city trips on relatively flat ground, the Touroll B2’s 250 W hub motor delivers smooth, efficient assistance exactly where it’s needed.
