E-bikes are divided into fully electric bicycles and electrically powered bicycles, as well as a mixture of these two ways of electric bicycles. Full electric bicycle we have seen more, commonly known as an electric bicycle with a turntable, twist the turntable is like a motorcycle gas door, the electric car starts to move forward;
Electrically-assisted bicycles add sensors to the pedal section, the e bike sensors will feedback your pedaling to the controller, and then the controller controls the motor to work, to achieve the mode of assisted forward motion, simply put, you pedal the motor to help you ride. We may have discussed e-bike battery replacement many times. In this article will detail the types of e bike sensor and compare the advantages and disadvantages to help you choose a more suitable e bike for you.

What is an e bike sensor
The sensor is installed at the five-way pipe in the pedal part of the two wheeler electric bike, and its function is to transmit information such as the cyclist’s pedaling frequency and pedaling force to the controller. After the sensor signal is transmitted to the controller, the controller will adjust the torque or power of the motor according to the size of the signal, and adjust the auxiliary rate, which is conducive to extending the range.
The key component of the electrically assisted bicycle is the booster sensor, which is mounted on the pedal part of the e-bike, and its function is to transmit to the controller information such as the current pedaling frequency and pedaling force of the cyclist. After the power sensor signal is transmitted to the controller, the controller will control the motor according to the size of the signal.
E bike sensor classification and working principle
At present, power bike sensors are roughly divided into two categories, one is speed e bike sensor, which transmits the pedaling frequency information, and the other is torque e bike sensor, which can be understood as transmitting the pedaling force.
The principle of speed e bike sensor is to measure the pedaling frequency to determine the need for assistance, the faster the pedaling frequency, the stronger the assistance, the slower the pedaling frequency, the weaker the assistance. The other type of bike sensor is the torque e bike sensor, which has torque type and pressure type torque, and transmits the pedaling force of the cyclist.
The principle of the torque e bike sensor is to obtain highly accurate torque values by measuring the subtle deformation of the metal surface that occurs after the pedal force is applied. By sensing the changes in the rider’s force on the pedals, cranks, and center shaft, it provides more realistic feedback on the actual riding conditions.
For example, in the case of low-speed climbing, although the speed and pedaling frequency are not high, but the pedaling is harder, then the motor receives the feedback from the torque e bike sensor, it should output more power to assist. This is closer to the real situation than just a pedaling frequency sensor.
Pros and cons of speed e bike sensor
Advantages of speed e bike sensor: instantaneous power can reach the maximum power, constant and smooth boost output. It is simple and not easy to be damaged compared with the torque tradition.
Disadvantages of the speed e bike sensor: it is power hungry compared to the torque one, and the motor may be over-assisted in fast rides, leading to stepping on empty laps.
The pain point of the speed e bike sensor: a single sensing of the assistance, a simple example, for example, when climbing or encountering a headwind, the human pedaling frequency and speed slows down, while the motor defaults to the rider does not need too much assistance. At this time, we can only rely on the screen to adjust the power level to match the power.
Pros and cons of torque e bike sensor
The torque e bike sensor is also mounted at the crank position, which transmits not the frequency of pedaling, but the force of pedaling, and compared to the speed e bike sensor, the boost is more precise, which means that the motor’s output is greatest when you pedal the hardest.
Advantages of torque e bike sensor: the most power-saving power-assisted motor system on the market, you can easily control the speed of the car with the pedal speed, that is, step on the car, the foot stops also stops, do not need to disconnect the power brakes, safer, when going uphill or want to accelerate, step on the foot a little bit harder, the torque sends out the signal of the added force, easy to go uphill.
Disadvantages of torque e bike sensor: expensive to build.
The speed e bike sensor is relatively simple and consists of an inductive contact and a magnetic steel ring, which is mounted on the foot hopping crank and rotates with the crank, and the small magnets on the figure sense with the inductive contact, thus transmitting information such as pedaling speed to the controller.
Comparison of torque e bike sensor vs speed e bike sensor
Torque e bike sensor is more complex and precise than speed e bike sensor, suitable for mountain bikes and other suitable for climbing the situation, in the uphill, the stampede force is larger, the need for greater motor power, and the speed can not keep up, so speed e bike sensor is not suitable. The torque e bike sensor matches this scene better.The speed e bike sensor has the advantages and disadvantages of simple structure and cheap price, which is more suitable for urban cars and road cars.
With speed e bike sensor, the motor output power is very small when riding on flat ground, which can save power and produce better driving experience. The torque e bike sensor measures the pedaling force exerted on the crank by the human foot, which is highly sensitive and much more practical than the speed e bike sensor in occasions that require a lot of force and slow speed, such as climbing hills, making climbing more labor-saving.
In fact, advanced e-bikes generally use a more advanced torque e bike sensor, which senses the changes in the rider’s force on the pedals, cranks, and center shaft, and it provides more realistic feedback on the actual riding situation.
For example, in low-speed climbing occasions, although the speed and pedaling frequency are not high, but pedaling harder, then the motor receives the feedback from the torque e bike sensor, it should output more power to assist. This is closer to the real situation than just a pedaling frequency sensor.
Speed e bike sensor, which is generally located on the inside of the front and rear forks, through the cable connected to the motor, and senses the wheel rotation, for the control of the dashboard to measure real-time speed, mileage and other data.
The principle is similar to the wired code meter, electromagnetic/infrared sensing, belonging to one of the standard sensors of electric power-assisted vehicles. Some manufacturers also arrange multiple speed e bike sensors in the motor and on the e bike frame to make their boost algorithms more accurate.
Finally, you can choose e bike sensor according to your own preferences and needs, but the most basic need to achieve the products are IP65 waterproof and dustproof grade, and comply with CE, EN15194, ISO13849-1, EMC and ROHS standards. There are other two-wheeler accessories related articles available such as motorcycle controller, motorcycle battery types, best motorcycle battery.
