Whether you’re an electric bike pro or complete beginner, choosing a new e-bike always takes some research. From motors and batteries to brakes, suspensions and gears, there’s a lot to take in. But a new e-bike is an investment, and getting familiar with the key components will help you make an informed decision for your future enjoyment.
An e-bike’s sensor contributes significantly to the riding experience, and the right choice for you will depend on what you want to get out of your electric bike. In this article, we’ll discuss the two main types of electric bike sensors found in modern e-bikes (cadence sensors and torque sensors) to help you select the best option for your needs.
What is an Electric Bike Sensor?
When weighing up e-bike options, it’s worth checking which type of sensor each contender has. While often overlooked, an electric bike’s sensor is an incredibly important feature. The sensor communicates with the motor, providing information on how much assistance the rider needs at any given time. Essentially, this means the quality of an e-bike’s sensor can make or break the riding experience.
What E-bike Sensors are Available?
Cadence sensors and torque sensors are the two most common types of e-bike sensors found in modern electric bikes.
-
A cadence sensor reacts to your pedalling in a simple way. When you start to pedal, the sensor sends a signal to start the motor. When you stop pedalling, the motor also stops.
-
A torque sensor reacts to both the movement of the pedals and the force you’re putting onto the pedals. This allows for a smoother, more intuitive ride. Essentially, when you’re pedalling hard, the motor naturally reduces its power assistance and lets you take the reins. On the flipside, if your pedalling gets less powerful, the motor ups its assistance.
What are the Pros and Cons of Each Type of Electric Bike Sensor?
Torque Sensor
Pros of a Torque Sensor
Torque sensors deliver power to match the effort you’re putting in, providing a great workout and a more authentic cycling feel. This adjustable assistance also makes them more efficient, potentially leading to better battery life and a longer range. Thanks to their heightened sensitivity, natural feel and efficiency, many modern e-bikes feature a torque sensor.
Cons of a Torque Sensor
Torque sensors are more sophisticated than cadence sensors. This means electric bikes with torque sensors are typically more expensive. The rider must also pedal constantly to keep the motor engaged. Because of this, torque sensor e-bikes are great for a workout, but might be less desirable if you want to stay fresh before your 9-5.
Torque Sensor E-bike Recommendation: ENGWE MapFour N1 Air City Electric Bike
With its lightweight portability and extended battery life, this electric bike is perfect for smooth city rides. 700c tyres provide stability for enhanced comfort, and the Shimano seven speed gear system offers adaptability for different metropolitan environments. Great for commuters who want that authentic ‘pushbike’ feel.
Cadence Sensor
Pros of a Cadence Sensor
Cadence sensors are more basic and easier to understand than torque sensors. They’re closely tied to the pedal assist function, can provide quicker acceleration with less rider effort, and will deliver power even when your input is lacking. This makes them a great choice for riders with an injury or medical condition that prevents large pedalling outputs.
Cons of a Cadence Sensor
Because the sensor doesn’t react to the force you’re applying and adjust assistance accordingly, they’re perhaps less suited to those who want a more intense workout. Some riders feel that electric bikes with cadence sensors provide a less ‘natural’ feel, and they can be prone to sharper acceleration jolts between modes. Typically, cadence sensors are more battery-intensive, too, which can limit their range. Proper pressure and pedal rotation are required to trigger this type of sensor, so they can be awkward on hill starts, especially if the e-bike is heavy or carrying a load. Engagement of a cadence sensor can also have a lag, although this varies from one system to the next.
Cadence Sensor E-bike Recommendation: Wisper 705 24” Step Through Electric Bike
Available with cadence sensor or torque sensor, and pedal assistance or full throttle, this electric bike is wonderfully customisable, versatile, and robust. A great choice for smaller cyclists and those looking for a smooth, quiet and comfortable ride.
Summary: Which E-bike Sensor is Best?
Torque sensors and cadence sensors each have distinct benefits and drawbacks, and the best option for you will depend on your needs. Cadence sensors offer affordability and more consistent assistance, while torque sensors are more efficient, delivering a natural and intuitive cycling experience.
In Conclusion:
-
An electric bike with a cadence sensor may suit a rider with an injury or medical condition, a rider that prefers more assistance, or a rider looking for a great affordable option.
-
An electric bike with a torque sensor may be the best fit for a rider who prefers a more authentic cycling experience, or one who likes to go on longer rides and get an intense workout.
