Pedal Assist Electric Bike Torque Sensor

Broadly speaking pedal assist systems fall into two categories basic pas sensors which detect just the speed at which the cranks are turning and torque sensors which also sense how hard the rider is pushing on the pedals.

Pedal assist electric bike torque sensor.

The harder you pedal the more power it gives to the motor. Unlike most pedal assist e bikes in this price range that only have a cadence sensor for pedal assist. This is different from a cadence sensor which measures simply how fast you are pedaling. These sensors are installed in the mid drive motors of the bikes.

You start to climb uphill on your bicycle and you begin to pedal harder. For this bike to work it needs to sense that you are pedaling and the motor will start to assist. Cheap cadence sensors are what can be found on most pedal assist system pas bikes on the market today. A torque sensor measures how hard the rider is pedaling to determine how much electric power to push to the bike.

A torque sensor is a type of throttle that determines how much juice to feed the motor based on how hard the rider is pedaling. With a torque sensor in use the electric bike s motor will increase its output relative to the amount of pedal force the rider is applying. Electric bikes or e bikes are gaining a lot of popularity. The reason for the lack of lag is that the tsdz2 mid drive motor has a built in torque sensor.

Pas torque sensors torque and basic pas sensors are used in conjunction with a v3 cycle analyst in order to provide automatic pedal assistance while riding the bike. Pedal assist torque sensor in contrast to a cadence sensor based pas a torque sensor uses some form of a strain gauge to determine how much force the rider is applying to the pedal. How to choose the best electric bike conversion kit. 9 levels of pedal assist and twist activated throttle only modes are available.

Two different sensors are installed on the bike. A torque sensor is connected to the chain or pedal which measures the force you apply to the pedal. The e bike will turn into a smart machine which will understand if you need a boost or not from the motor depending on the riding conditions. If you pedal lighter less power goes to the motor.
