One of the biggest perks of electric bikes is their pedal-assist systems (PAS), which engage the motor when the rider pedals, providing faster, longer, and farther rides than traditional bicycles. However, there are two main types of pedal assist systems: torque and cadence sensing. 

Torque Sensors offer a more intuitive and natural riding experience as the motor power is proportional to the force applied by the rider. This means that the assistance level adjusts seamlessly as you pedal harder or softer, giving you a sense of control and a similar feel to traditional cycling. 

On the other hand, Cadence Sensors activate the motor based on the rotation of the pedals, providing a consistent level of assistance regardless of the rider’s effort. This can be beneficial for maintaining a steady speed or for riders who prefer a more relaxed and consistent riding experience.

Both cadence and Torque Sensors turn ebike motors to move riders forward, but there are a few key differences in how they work. Today, we will look at the differences between the two ebike sensors to help you decide which one might be best for you.

Types of Electric Bike Sensors?

The sensors on an ebike are an integral part of the bike’s pedal-assist (PAS) mechanism. These sensors connect the bike’s motor to the rider, allowing the machine to provide pedaling assistance.

Torque Sensors

The amount of pressure or force the rider puts on the pedals is measured by torque sensors. A signal is sent to the motor based on how hard the cyclist is pedaling. This signal activates the motor to provide power in line with the cyclist’s pedaling. 

The motor assistance is adaptive in real-time in response to the rider’s input, making for a more responsive and dynamic riding experience thanks to torque sensors. The technology provides a sense of command and oneness with the bicycle, evoking an experience akin to classical cycling.

How Does it work?

Torque sensors are important for electric bikes because they can tell how hard the rider pushes down on the pedals. Its main job is to measure how hard the person is working and send that information to the electric bike’s motor so it can change how much help it gives.

The torque monitor measures how much force is used as soon as the rider pedals. It tracks how much pressure or torque the rider’s legs put on the pedals in real time. The electric bike’s motor processor gets this information, processes it, and then decides how much help to give. This means you can get increasingly higher output from the motors with lesser pedal input. 

Benefits of the Torque Sensors

Torque sensors in electric bikes offer several notable benefits that enhance the overall riding experience. Here are some key advantages of using torque sensors:

1. Natural and intuitive riding feel: Torque sensors make riding more intuitive. The assistance level from the electric motor is directly proportional to the force applied by the rider on the pedals. As you pedal harder, motor assistance increases, simulating traditional riding. The Himiway Zebra, fitted with the best torque sensors, seamlessly transitions from manual to assisted pedaling.

2. Precise and responsive assistance: Torque sensors in the electric motor react to your pedaling, signaling the pedal force sensor as it instantaneously changes the motor’s assistance. Its responsiveness helps climb steep climbs and accelerate from a stop. Torque sensors allow the electric bike to adjust to your riding style and deliver the right support.

3. Efficient energy utilization: Torque sensors help optimize the energy utilization of the electric bike’s battery. The electric motor only kicks in when needed since the assistance is directly linked to your pedaling force. This efficient power delivery system maximizes the range and longevity of your battery charge. The motor aid intelligently adjusts to your pedaling effort, helping you conserve energy and go farther.

Cadence Sensors

Cadence sensors function in response to pedal revolutions. When the rider begins to pedal, a signal is sent to the motor to begin assisting. Torque sensors detect the force applied by the cyclist, while cadence sensors only measure the rider’s speed.  Instead, they detect whether or not the cyclist is pedaling. The level of help this sensor provides remains constant regardless of the rider’s exertion. It keeps going at a constant rate, making it perfect for passengers who would rather take it easy.

How does it work?

Typically, a cadence sensor is installed near the bottom bracket area of the fat electric bike, where it can accurately monitor the movement of the pedals. It typically consists of a magnetic or optical sensor and a magnet attached to the crankset or pedal crank arm.

As the rider pedals, the magnet attached to the crankset passes by the cadence sensor at regular intervals. This creates a magnetic or optical signal that the sensor detects. The sensor then sends these signals to the electric bike’s motor controller, which interprets the data and decides when to activate the pedal-assist function.

When the motor controller receives the signals from the cadence sensor indicating that the rider is pedaling, it instructs the electric motor to provide the predetermined level of assistance. The motor engages and assists the rider’s pedaling efforts, delivering power to propel the fat electric bike forward.

Benefits of the Cadence sensors

Cadence sensors in electric bikes offer several benefits that enhance the riding experience. Here are some key advantages of using cadence sensors:

1. Simplicity and ease of use: Cadence sensors provide a straightforward, user-friendly experience. They activate the motor assistance automatically when they detect pedal rotations, eliminating the need for additional adjustments or manual control. This simplicity makes cadence sensors suitable for riders of all skill levels, including beginners and those who prefer a hassle-free riding experience.

2. Consistent assistance: One of the significant benefits of cadence sensors is their ability to provide consistent assistance. Once the rider starts pedaling, the sensor maintains a steady level of assistance regardless of variations in the rider’s pedaling effort. This ensures a smooth and predictable riding experience, allowing riders to maintain a constant speed and rhythm throughout their journey.

3. Smooth acceleration and deceleration: Cadence sensors contribute to smooth acceleration and deceleration while riding. As the sensor detects pedal rotations, it prompts the motor to assist, allowing for effortless starts from a standstill and smooth transitions between different speeds. This feature is particularly beneficial for urban commuting or stop-and-go situations, where seamless acceleration and deceleration enhance overall ride quality.

5. Relaxed and leisurely riding experience: Cadence sensors are well-suited for riders who prefer a more relaxed and leisurely biking experience. The consistent level of assistance allows riders to maintain a comfortable pace without requiring intense pedaling efforts. This makes cadence sensors ideal for leisure rides, scenic routes, or riders with physical limitations or who prefer a more effortless biking experience.

Which is better? Torque or Cadence Sensor.

Ultimately, you should choose between cadence and torque monitors based on how you ride, what you like, and what you need. If you want a smooth and steady ride, cadence sensors may be a good choice for you. But if you want a more natural and personalized ride that responds immediately to how hard you pedal, torque monitors will likely be a better choice.

You should try electric bikes with both types of sensors to see which one fits your riding needs better and gives you the right amount of help and control.

The Himmiway Advantage

Himmiway has produced some of the best e-bikes in America. Amongst these bikes are the Himiway Zebra, which you can have fitted with either the Cadence sensor or the Torque sensor depending on your preference, as we have discussed. 

Conclusion

Your riding style and goals will determine whether you’re better off with a torque or cadence sensor. Riders who like a more natural experience and consistent assistance level frequently use torque sensors. They’re great if you plan on riding in rough terrain or want a more responsive fat electric bike. However, commuters and leisure riders who value regular support and a more comfortable ride choose cadence sensors.

Knowing how these electric bike sensors differ will help you choose the best pedal-assist system for your needs and tastes. These sensors are crucial to improving the quality of your electric bike ride, whether you’re looking for a thrilling adventure or a relaxing commute.
