About Torque Sensor

Cadence Sensor

a cadence sensor measures the speed at which the pedals are turning. It provides feedback to the electric motor, allowing it to adjust the level of assistance provided based on the rider's pedaling speed. Cadence sensors are generally less expensive than torque sensors, but they can provide a less natural riding experience. With cadence sensors, the motor output is based solely on the rider's pedaling speed, so the rider may experience a lag in assistance when starting from a standstill or when riding uphill.

Torque Sensor

A torque sensor measures the amount of force applied to the pedals by the rider. It provides feedback to the electric motor, allowing it to adjust the level of assistance provided based on the rider's effort. Torque sensors are considered to be more advanced than cadence sensors because they provide a more natural riding experience, with power assistance that feels more like traditional cycling. With torque sensors, the motor output is proportional to the rider's effort, so the harder the rider pedals, the more assistance the motor provides. This means that torque sensors are ideal for riders who want to maintain a consistent level of effort throughout their ride, regardless of terrain or incline.

Why torque sensor?

  1. More natural riding experience: Torque sensors provide electric assistance that is proportional to the rider's effort, making it feel more like traditional cycling. With cadence sensors, the motor output is based solely on pedaling speed, which can feel less natural.
  2. More precise assistance: Torque sensors can detect even small changes in the rider's effort and adjust the electric assistance accordingly. This means that riders can maintain a consistent level of effort throughout their ride, regardless of terrain or incline.
  3. Better battery efficiency: Torque sensors can help to conserve battery life by providing assistance only when needed. With cadence sensors, the motor may continue to provide assistance even when the rider is not exerting much effort, which can drain the battery more quickly.
  4. Easier to start from a standstill: Torque sensors can provide immediate assistance when starting from a standstill, making it easier to get going. With cadence sensors, there may be a lag in assistance when starting from a stop.
  5. Safer and more stable ride: Torque sensors can provide a safer and more stable ride by adjusting the electric assistance based on the rider's effort. This means that riders can maintain better control of their bike, especially when riding at higher speeds or on uneven terrain.
