1. Manual controller: The manual controller is one of the common control devices on electric bicycles. Typically mounted on a bicycle's handlebars, hand controls allow the rider to operate the electric power-assist system with a simple button or handle. This control method is simple and intuitive, and the rider can adjust the level of electric assistance at any time as needed to better adapt to different riding environments and personal preferences.
Some manual controllers are also equipped with a display screen, which can display information such as the current power assist mode, speed and remaining power in real time, providing a more intuitive riding experience and control operations.
2. Cadence sensor: The cadence sensor is a device that can detect the rider's cadence and is often used to control the electric power assist system of electric bicycles. When the rider starts to step on the pedals, the cadence sensor will sense the change in cadence and activate the electric assist system according to the set assist mode. Generally speaking, the cadence sensor responds quickly and can achieve instant electric assist response and provide a smooth riding experience.
In addition, the cadence sensor can also help save battery energy because it only activates the electric power assist system when the rider steps on the pedals, avoiding unnecessary waste of energy.
3. Torque sensor: The torque sensor is an advanced control device commonly used in the electric assistance system of high-end electric bicycles. The torque sensor senses the amount of force the rider exerts on the pedals and adjusts the output level of the electric assist according to the amount of force. This control method is more intelligent and precise, and can dynamically adjust the electric power assist according to real-time riding status and road conditions, providing a more comfortable and efficient riding experience.
The torque sensor can also realize adaptive adjustment, that is, intelligent adjustment according to the force application of different riders, so that the electric power assist system can better adapt to different riding habits and preferences.
4. Electric power assist mode selector: The electric power assist mode selector is a device used to adjust the electric power assist output level. It is usually equipped on the control panel of an electric bicycle, and the rider can switch between different assist modes through a selector, such as economy mode, standard mode and sport mode.
Each assist mode corresponds to a different level of electric assist output. Economy mode provides weaker assistance and is suitable for long-distance riding or energy-saving mode, while sports mode provides stronger assistance and is suitable for climbing hills or accelerating. The electric power assist mode selector can flexibly adjust the power assist level according to riding needs and environment, providing a more personalized and comfortable riding experience.
