The Ultimate Guide to Torque Sensor eBike - Thebicyclegeek

As eBikes become more popular and bicycling becomes more troublesome for people wanting to travel long distances, getting a pedal-assisting system is an excellent investment. The torque sensor eBike is an innovative tool to help new and old cyclists on their rides.

Torque sensors for electronic bikes are pedal assistance devices that manage the power output from an eBike’s motor. This sensor requires the rider to use the same amount of energy they wish the motor to exert and will double that output to allow more distance coverage.

What Is A Torque Sensor eBike?

The torque sensor eBike is a pedal-assisting electronic bike that automatically adjusts the battery power output according to how hard or light you pedal. Electronic bikes with pedal assist technology (PAS) are invaluable for beginner riders unfamiliar with eBikes or those who need assistance due to medical conditions.

PAS is excellent for conquering mountains or rough terrain and is simple to use. There are two types of sensors: the torque sensor, which is automatic and requires more pedal exertion from the rider, and the manual cadence sensor, which exerts most of the power for you.

The torque sensor’s automatic energy adjustment allows for a seamless output change from the motor and almost mimics the feeling of a conventional bicycle. This clean power change eliminates some of the lagging that occurs when using a cadence sensor.

As you pedal, the torque sensor measures the strain of a complete pedal stroke and doubles your exertion. So, when you pedal softer, the battery will exert less power. When you pedal harder or faster, the battery matches it, allowing you to travel further and have effortless control.

How Does The Torque Sensor Work?

Torque Sensor - Thebicyclegeek

Pedal assisting torque sensors are a strain-based technology that changes mechanical movement (in this case, rotational) into electrical output. From the first rotation of your bike pedal, you create a stress signal to start the eBike’s motor.

The sensor measures your pedal strokes up to 1000 times per second, ensuring that the power output from the battery matches the energy you put into the motion. A two-step process needs to be triggered for the sensor to feed power into the motor: apply pressure and rotate the pedals.

Because the sensor is triggered automatically on the first sign of rhythm and force, you don’t need to manually adjust power levels to slow down or speed up. Using the torque sensor, you don’t need to grow accustomed to power shifts either. So, from the very start, you have complete control of how fast you are going and how much effort you should exert.

Benefits of A Torque Sensor Electric Bike

The torque sensor electric bike is an excellent means of covering long distances while still having the accomplishment of putting in your time and effort. It offers a somewhat natural riding experience and is highly responsive.

Pedal Assistance

This system takes its title as an assisting mechanism and sticks to it. Instead of simply depositing energy in what might be wasteful levels, the torque-based PAS only uses energy as it is needed. It assists riders rather than overtaking the riding experience.

Using the torque system means you get out what you put in. You get to travel long distances, which might seem superhuman but you are not left drained as on traditional bikes or unaffected as you might be on a cadence-based PAS.

To move faster and travel further, you must pedal faster and harder to achieve your desired speed. Your effort is integral to the continued movement and speed of the bike, but every effort is handsomely rewarded.

More Natural Riding Experience

Like a traditional bicycle, on an eBike with torque-based PAS, you are propelled forward in a leisurely ride or a vigorous cross-country trip when you pedal. Unlike a conventional bike, the pedal assistance of a torque sensor doubles the effect without doubling the effort.

You must apply more speed and force to your pedaling to reach the bike’s full potential. This process is authentic to the riding experience, and since your pedaling determines the power output, the shift of high to low or low to high output goes unnoticed.

This seamless transition makes it feel like there is no motor and ramps up the excitement of your efforts. With torque-based PAS, you are not relying on the system but on your ability as the rider. You are achieving greatness, not the bike.

More Responsive

Instead of only measuring if you are pedaling and doing the rest of the hard work for you, the torque pedal sensor measures both if and how fast you are pedaling.

The bike’s responsiveness means it starts moving as soon as you put pressure on the pedal. Your movement is what kickstarts the motor and keeps the speed and, therefore, the power flowing. When you stop exerting effort, the engine will as well.

Because it automatically adjusts the power output, the change in power level goes undetected by the rider. This control creates a sense of unity between the rider and the bike.

Disadvantages of Torque Sensor eBike

Despite all the benefits of the torque-based PAS, there are still drawbacks. While the natural experience may be a plus to some, the extra effort may be a drawback for others. These sensors are also costly.

Torque sensors are relatively modern and have quickly become popular. The cost for a torque-based PAS on your eBike can be staggering, so it is best to test the bike before deciding whether you want to make the purchase or whether a cadence pedal assist may better suit you and your budget.

A quality electric bike will cost you upwards of $1,500, and a customized bike may cost above $8,000. Adding a torque sensor PAS to your eBike will add another $200-400 to the cost of a mainstream bike.

The main cost comes from the motor and battery on the eBike. At the very least, you will be able to use your battery power to its maximum extent as it will recharge as you go further – a feature bolstered by the very nature of the torque sensor.

Torque Sensor Vs. Cadence Sensor, Which Is Better?

Torque and cadence sensors are great pedal assist systems that allow higher distance coverage and ease of movement than traditional bicycles. However, they are pricey and require careful consideration of how much assistance you need.

The cadence system will do most of the work for you, while the torque system works with you. Because the torque system works on the strain of your efforts, you need to produce more effort to maintain and reach higher speeds – much like a traditional bike.

The cadence-based system requires much less effort from the rider as it only requires you to move the pedals (strain irrelevant) for the motor to provide power. However, the manual adjustment of power levels can equal a rougher ride and leave you feeling disconnected from the process.

Another factor to consider is battery use. The cadence sensor ensures that the battery exerts output constantly and consistently, which can lead to battery drainage. While the torque-based sensor only distributes as much power as the rider requires at any given time, allowing for power saving.

Ultimately the better sensor is based on the rider’s needs and desired outcomes. The torque sensor is for you if you want to cover more distance and exercise more while feeling rewarded for your efforts. The cadence sensor may be better suited for someone who needs extra assistance or has a defined budget.
