Torque, also known as torque, describes in the bicycle context the force that acts on the crank or rear wheel to drive the bicycle. It is a physical quantity that is measured in Newton meters (Nm) and significantly influences the acceleration and efficiency of the drive. Torque is calculated from the formula:
Torque (Nm) = Force (N) × Lever arm (m)
E-bike motors :
On e-bikes, the torque indicates how much support the motor offers. Higher values (e.g. 85 Nm) mean more support, which is particularly beneficial on steep climbs or for heavy riders. Lower values (e.g. 40 Nm) are sufficient for city traffic or light terrain.
Power transmission :
Torque affects how efficiently power is transferred from the rider through the crank and chain to the rear wheel. A long lever arm (as in longer cranks) can increase torque.
Maintenance and installation :
When tightening screws, e.g. on cranks or disc brakes, the correct torque is crucial to avoid damage caused by over- or under-tightening. Torque wrenches help to maintain the correct values.
Performance analysis :
Especially in professional sports, torque is often analyzed in combination with cadence to determine a rider's power (in watts). Watts are calculated from torque × cadence.
Torque directly influences driving dynamics and performance. A better understanding of this helps you to use your own power more efficiently, compare e-bike options better or maintain the equipment optimally.
Immer mehr Menschen steigen vom Auto aufs Fahrrad um – und das nicht nur in der Freizeit. Das sogenannte Dienstrad hat sich in den letzten Jahren als attraktive Alternative zum klassischen Firmenwagen etabliert. Insbesondere E-Bikes stehen bei Arbeitnehmern und Arbeitgebern hoch im Kurs. Warum? Sie sind nicht nur nachhaltig, sondern oft auch kostengünstiger und gesünder.
In recent years, a surprising trend has taken over the streets and beaches of the Netherlands: the fat bike. The wide-tired bikes, originally designed for sandy deserts or snowy landscapes, are now a common sight in one of the most bike-friendly countries in the world. But what is behind this boom, and why is the fat bike such a good fit for Holland?
