How can I knowl if a torque sensor is used on a power-assisted bicycle? [ 2022-07-25 ]

The most straightforward way to tell if an e-bike is using a torque sensor is to try pedalling continuously with the lightest gear ratio. Generally speaking if the bike is just using a pedal sensor, the power output will not correlate with the pedalling effort, i.e. the bike will keep accelerating.

Design and development of a torque sensor based on ebike mid-mount system [ 2022-07-25 ]

Torque is a fundamental parameter in the performance of a mechanical transmission system [1]. The use of appropriate torque measurement devices to measure and control torque online and in real time is of great importance to ensure the stable operation of the whole system. Most of the current electric bicycles are driven by hub motors, which are placed at the front or rear wheels of the bicycle, causing the centre of gravity to lean forward or backward, which is not in line with people's riding style, and the speed of the bicycle is completely dependent on the handlebar control, which is a major traffic hazard.

What different between torque sensor and cadence sensor ? [ 2023-03-17 ]

Speed Sensor vs Torque Sensor, What Are the Differences? If you are to purchase an ebike and are doing research on which one you should own, you may hear about two kinds of sensors — speed sensor and torque sensor. Different ebikes for sale apply different sensors. As it is an essential component of an ebike, you must understand which one of them fits you and meet your requirements. In this article, we will share with you all the details about both the speed and torque sensors, including their pros and cons and advice for making a choice between them, just stick with us.What Are Ebike Sensors? Whether it is torque or speed sensor, both of them are all about PAS(pedal assist system). They send a signal to ebike motors to activate the PAS, but how they determine the output of PAS is different, which can have a huge impact on ebike performance. We will talk about exactly how they work in detailA speed sensor is called a cadence sensor as well. Basically, an electric bike with a speed sensor is a better choice for amateurs as it requires fewer efforts to reach a higher speed. It determines the output of PAS by setting it on the display. A speed sensor could be pretty flexible as it determines the power output of the PAS based on the display settings. However, if you want to gain more comfort with it, it is recommended to shift to a lower gear because it will take fewer efforts to pedal to send the signal. Taking an example, it has 7 levels of PAS, and the output of each of them can be set on the display. Once you start to pedal, the speed sensor will send a signal to the motor, making it provide the set power output to the ebike.

Explaining the technical principles of electric assisted bicycles [ 2022-10-24 ]

With the release of the electric folding bicycle, interest in this relatively new travel tool has been aroused, but many people do not know much about this type of electric bicycle, and when they hear the price of an electric bicycle they may wonder: why buy a bicycle that requires pedals when three thousand is enough to buy an electric car? This shows that there are some misconceptions about these products, so today we will talk about the technical principles of electric assist bicycles to give you a better understanding of these products. Although electric bicycles and electric assisted bicycles are both electrically assisted vehicles, it is important to realise that there is a strict distinction between electric assisted bicycles and electric bicycles, so they do not belong to the same category of products. The more direct difference is that an electric bicycle does not have a purely electric mode of riding, but rather requires a 'human + electric' hybrid drive, which is fundamentally different from the purely electric mode of an electric car, and the way you ride such a vehicle is no different to riding a bicycle. The electric power provides a solution to the problem of cycling effort, and with the human power, it is possible to go beyond the range of a typical electric bicycle with a modest battery, enabling longer distances to be travelled. The core power technology of electric bicycles Firstly, the electric bicycle was first developed in Japan and uses the 'Power Assist System', a torque sensor-based hybrid power system that can be driven by human power and electricity. It can also be driven by human power alone. The Power Assist bicycle is a personal vehicle that offers the lightness and convenience of a bicycle, while compensating for the burden of cycling up hills, into windy conditions and when carrying loads. It is based on a conventional bicycle and is equipped with a torque sensor-based power system with motor and battery. The main difference from an e-bike (e-donkey) is that instead of adjusting the amount of power through the handlebars, it uses torque sensors to sense how hard the rider is pedalling and, depending on the amount of human effort, to provide the rider with the appropriate power support. At present there are many companies with power assist systems worldwide, but there are only a few that use torque sensors in their power assist systems, such as Bosch and Maha in Germany, Yamaha and Panasonic in Japan. These companies are basically related to the automotive and new energy industries and have a very high technology development threshold, making it difficult for general companies to enter.

E-bike booster sensors [ 2022-10-24 ]

The e-bike booster sensor is used on smart e-bikes and is one of the core components of smart e-bikes. According to the regulations of the European Union and Japan, e-bikes must be pedal-assisted (i.e. smart e-bikes) in order to be classified as a non-motorised vehicle. In China's non-motorised vehicle management, such as Shanghai, Beijing, Shenzhen, Hangzhou and other places require the assembly of a central axle and a booster sensor, in order to achieve the requirements of start-up assistance and power-saving riding. 1. the electric bicycle booster sensor is a national patent technology product with high technical content of electromechanical integration. 2. When riding, the booster sensor detects the pedal torque and sends the detection signal to the PC side of the intelligent controller to synchronously control and adjust the motor speed and output power, so that the riding torque is proportional to the motor output torque, in order to achieve the purpose of doubling the torque. 3. The motor is controlled automatically by the turnbuckle when the pedaling stops; it is safe and energy-saving for leisure and fitness. 4. Effective in increasing the range and extending the life of the battery. The main application of the booster sensor for electric bikes is the detection of the booster signal. It is equipped with a disk of 5-10 magnets, and the sensing distance can reach up to 6.0mm. In China, 5 magnets are generally used, while the 8 piece controller requires special parameters. When the stirrups are rotating, the sensor outputs a low-level pulse and the controller gives the corresponding motor torque according to the pulse frequency. The specific parameters are set by the controller in accordance with the settings! The material used for the disk and the housing is ABS, which has a good toughness and strength at ±40°C. In the existing production enterprises, there are mainly macro ship, crystal Heng and other brands as the mainstream suppliers, its quality has been recognized by the market!
