ED20: Upgrade your cycling experience at a quite small cost

Unlike the traditional eBike system that uses mechanical finger shifting, Magene includes electronic shifting for the first time. ED20 can be integrated into your eBike system through wired connection and powered by the eBike battery. The performance will be more stable through a wired connection and can improve the cycling experience significantly at a very small cost.

The ED20 small-volume wire actuator solution can realize gear shifting via buttons, which can effectively reduce finger fatigue or pain and is more accurate. Moreover, the handlebar is more concise by removing the mechanical shifting. The product is small in size, easier to install and hide, and the cycling experience can be upgraded without any bike modification.

In addition, ED20 electronic shifting is also an excellent choice for users or clients who want to improve the riding experience at a low cost. Compared with a direct electronic drive, the cost of the small volume wire actuator can be reduced by 80%, greatly reducing the upgrade cost. As a separate component, the ED20 is also very convenient to disassemble and use and can be installed in any position of the eBike, or hidden in the bike frame.

Torque Sensor vs. Cadence Sensor: which is better?

On an e-Bike, the Torque Sensor or the Cadence Sensor is important in the e-bike system for improving performance and operation. Below, we will briefly compare and analyze them.

Torque Sensor

The torque sensor is a device that senses changes in the rider’s outgoing force acting on the pedals, cranks, and bottom bracket. It measures the torque or force changes generated during riding. The torque sensor senses the changes in real time and transmits the signal to the controller to adjust the motor’s output. For example, in the case of climbing a hill at a low speed, although the speed and pedaling frequency are not high, the rider will need more power to pedal, and then the motor receives the feedback from the torque sensor and will output more to assist the rider. Therefore, the torque sensor can help to provide more precise power output, thus optimizing the riding experience.

Cadence Sensor

The cadence sensor is more focused on monitoring how often the rider pedals. It can sense the rhythm and speed of the rider’s pedaling in real-time and transmit this signal to the controller. The working principle of cadence sensors is generally through physical contact, such as via metal contacts or magnetic induction, to detect the pedaling frequency. There is also some new cadence sensor that adopts non-contact design, such as through infrared or ultrasonic wave to detect the pedaling frequency. The cadence sensor is critical in speed control and mileage calculation. For example, when calculating the total mileage, it is necessary to multiply the distance and the number of times of each pedal stroke, and the number of times of each pedal stroke needs to be provided by the pedaling frequency sensor. In addition, the cadence sensor can also help control the power output at a specific pedaling frequency to adapt to different riding needs.

In summary, torque and cadence sensors are critical in adjusting the electric assist during the riding. Their main difference lies in the different physical quantities they measure: the torque sensor mainly measures the torque or force during riding. However, the cadence sensor focuses on the frequency of the rider’s pedaling. With its help, the motor’s power output will be precisely adjusted during the riding, providing a better riding experience. At the same time, their presence also makes e-Bike much more intelligent and better to meet the various needs of users.
