Hill climbing performance in-depth showdown: Why is motor torque crucial in European cities?

Unlike the flat and open urban new arterial roads in China, many historic cities in Europe (such as Montmartre in Paris, the rolling neighborhoods of Lisbon, or the volcanic hills of Edinburgh) are full of continuous uphill slopes with extremely steep angles. When riding on these road sections, it is not the wattage marked on the motor (the wattage mainly determines the maximum speed on flat roads) that determines whether you will be sweating and flushed, but the **torque (Nm, Nm)**. The EIP power evaluation team conducted a hill-climbing showdown on a number of models with different torque specifications on steep slopes. Actual measurements show that for a lightweight urban rear-wheel-drive vehicle with a nominal power of 250W but a torque of only 35Nm, when facing a steep slope with a gradient greater than 12%, the motor’s assistance strength declines significantly, and the rider must stand up and pedal hard to keep moving forward. However, high-end models equipped with DJI’s Avinox mid-mounted motor system and with industrial-grade terrifying torque of up to 105Nm can run on the same slope as if they were on the ground. Even a weak woman can easily reach the top with an elegant and light pedaling frequency at the full auxiliary speed limit of 25 kilometers. This fully proves that European consumers with complex terrain should unswervingly regard high-torque mid-mounted motors as their first choice.
