All About eBikes: Torque vs. Cadence Sensors
If you’re new to ebikes or just diving into the details, you’ve probably come across terms like torque sensor and cadence sensor. These are two different ways that pedal-assist systems detect your pedaling and decide how much help to give you. While both offer unique benefits, the best choice really comes down to how you like to ride.
The Bosch motors in Gazelle ebikes offer the best of both worlds, utilizing a combination of torque and cadence to inform the level of electric assist the motor delivers. We’ve chosen this technology because it offers a comfortable natural feel paired with the most efficient use of power, especially when you understand how to ride with it. But let’s take a closer look at both systems so you can make an informed decision.
Torque sensors measure how hard you’re pedaling. The more force you apply to the pedals, the more power the motor delivers. It can help the rider get going faster since that first pedal is often the most resistant. While this style can feel more responsive, it means that the rider must exert quite a bit of effort to trigger the electric assist on their bike. This can be counterintuitive since as you down-shift gears when coming to a stop or going uphill, the resistance you’ll feel through your pedals is lighter.
Pros of torque sensors:
Power output adjusts dynamically to your effort
Often feels more reactive to your pedaling
Great for fitness-focused or performance-oriented riders
Things to keep in mind:
Requires more consistent effort to maintain higher assistance
Can feel more physically demanding, especially on longer rides

Cadence sensors detect how fast you’re pedaling. Once you start pedaling, the motor provides power based on your selected assist level and the rotation of your wheels. On an ebike with a cadence sensor it’s important to shift gears just like a regular bike. If your bike features a chain and derailleur you should make sure to shift down to your easiest gear as you come to a stop. Internally geared hub bikes can shift gears while stopped.
By being in a lighter gear you can take full advantage of the electric assist and really spin up your wheels to get going. Similarly, going uphill on a Gazelle is a breeze when you are shifting gears properly. With some practice you’ll learn how to efficiently shift gears for a truly effortless ride.
This style sensor can lend to a smoother, more predictable ride ideal for commuting, casual cruising, or just enjoying the outdoors without breaking a sweat.
Pros of cadence sensors:
Easier on the knees and muscles, great for relaxed riding
Assistance is steady and consistent at any pedal pressure
Allows you to manage your energy and battery more effectively
Things to keep in mind:
May feel less powerful if you are not shifting gears
Takes practice to learn how to efficiently shift gears
Not all cadence systems are created equal. Bosch ebike motors use a combination of input from both the cadence and torque sensors on the bike so the assist feels natural, not jerky or delayed.
Used correctly, a cadence-based system gives you a lot of control. You can:
Choose a comfortable pedal rhythm and let the motor do the hard work
Adjust assist levels on the fly to match your terrain
Conserve battery power by using higher gears and moderate cadence.
There’s no one-size-fits-all answer. If you you like a highly responsive feel, a torque sensor may be a better fit but if you’re looking for a ride that’s easy, smooth, and efficient a well-tuned cadence sensor system might be your perfect match.
If you appreciate the best of both worlds and want to enjoy the benefits of both systems, an ebike with a Bosch motor would be a great choice.
At the end of the day, both systems have their strengths. What matters most is how you want to ride.
