E-Bike: Cadence Control vs. Torque Control

When it comes to selecting an E-bike motor, there are many factors to consider. One significant factor is the type of motor control. E-bike motors can be operated using either cadence or torque control, and both have their advantages and disadvantages...

Cadence Control:

Cadence control, also known as speed control, is the control used in Bafang BBS01/02/HD motors. In this mode, the motor provides assistance based on pedal revolutions. As soon as the crank arms start moving, the motor assists up to the power or speed limit (whichever is reached first) of the selected assistance level. The crank arms can be moved without applying force - the motor only supports because of the pedal movement.

Advantages:

• Easy to use: Cadence control is easy to understand and use, making it particularly attractive for beginners.
• Maximum support without effort: Since the motor's power is based on pedal movement, it doesn't matter whether the rider is pedaling with a lot of force or lightly.
• Extended battery life: The constant power setting can help extend the battery life since the motor is not as heavily stressed.

Disadvantages:

• Less dynamic: Cadence control may not respond as well to changes in riding style, such as in off-road terrain.
• May be less intuitive: Motor assistance remains the same regardless of whether the rider is exerting a lot or minimal effort.

Torque Control:

In contrast, torque control is based on the force applied to the pedals. The harder you pedal, the more power the motor generates. With torque control, it's much easier to fine-tune the motor's power output. Even in the highest assistance level (max power and speed), the E-bike can be ridden slowly with minimal pedal effort - something that cadence control cannot achieve, as the motor aims to meet the power and speed requirements of the highest assistance levels with crank movement. CYC Motors feature torque control.

Advantages:

• Intuitive control: Torque control allows you to intuitively adjust the motor's power with your pedal pressure. The harder you pedal, the more power you receive.
• Excellent for hilly terrain: This control method is particularly well-suited for rides in hilly terrain, as the motor dynamically responds to inclines.
• More enjoyable riding: Many riders appreciate the sportier and more dynamic nature of torque control.

Disadvantages:

• Slightly more complex: Torque control may require a bit more practice and fine-tuning to find the optimal riding style.
• Can reduce battery range: Since the motor is under more strain, using torque control may result in slightly shorter battery range (motor power varies).

Conventional E-bikes use torque control. This type of control is considered more modern and natural. Cadence control was popular, especially in the early years, but is gradually being replaced by torque control.
