It can be tricky to decide whether you want an electric bike with a cadence sensor or a torque sensor. Both have advantages and disadvantages, and each suits different circumstances.
The type of sensor in your e-bike makes a difference to how the bike feels to ride, how efficient it is, and how much you enjoy riding it.
Most e-bikes make you choose one or the other. But the Mooncool POP Folding Electric Bike gives you the best of both worlds. It comes with a torque sensor as standard, and lets you switch to cadence sensor mode whenever you want. High-end e-bikes like those from Velotric use SensorSwap technology to offer this feature, and the POP brings it to a much more accessible price point.
Here is a close look at what each sensor does, why the difference matters, and how the Mooncool POP uses both to adapt to your riding.
Torque Sensor: Natural, Ideal for Workouts
Here is the simplest way to think about it. A torque sensor reads how hard you are pushing on the pedals. When you pedal harder, you get more motor assistance. Ease off, and the motor eases off with you. This is because the sensor is measuring your actual effort rather than just detecting movement.
A cadence sensor works differently. It detects when you are pedaling and gives you a fixed level of assist based on how fast your legs are turning. It does not matter how hard you push. As long as you are pedaling at a certain speed, you get the same level of help.
This means torque mode feels more like a regular bike because the assistance is natural and proportional, which most riders prefer for commuting and varied terrain. Cadence mode feels more like a conventional electric bike. The assist is steady and predictable, which some riders find easier to manage on long flat rides where they just want to settle into a rhythm and go.
There is also a difference in how efficiently you use your battery. Torque mode only delivers what your effort demands, so it tends to use less power on comfortable sections. Cadence mode can deliver full assist even when you do not need it, which is why riders who need a longer range are usually better off in torque mode.
The Industry Trend: Dual Sensor Switching Technology
In 2026, the ability to switch between torque and cadence sensors is becoming a flagship feature on premium e-bikes. Riders have realized that different rides call for different kinds of assistance, and only having one mode for the life of the bike can be quite limiting.
For example, a hilly commute where you want to work hard and arrive feeling like you have exercised is a different kind of ride from a long Saturday leisure ride where you just want to cruise without effort. Both are better with a different sensor. Having both available changes how useful the bike is.
The Mooncool POP has this switching technology built in. All you need to do is select the mode from the display. You don’t need any tools or technical knowledge, and you don’t need to stop. The switch takes a few seconds, and the difference in feel is immediate.
Inside the POP's Dual Sensor System
Workout Mode activates the torque sensor and pairs it with the Shimano 7-speed drivetrain. The motor responds to your effort in real time, which means the harder you push, the more it helps. For riders who want to use their e-bike as part of an active lifestyle, this mode is ideal. You still get a proper workout because the motor amplifies your effort rather than replacing it.
When you switch to cadence mode, the bike's character changes. The motor delivers a steady level of assist based on pedaling speed. This mode is for longer days, tired legs, or any ride where you want to get somewhere comfortably without working too hard. It is also the easier mode for new e-bike riders to get used to, as the output is consistent and predictable from the moment you set off.
And when you want the motor to do everything, you can use the twist throttle. Use it to set off from a standstill without building pedaling momentum, or use it on sections where you want a rest. It is particularly useful when the rear rack is loaded, and you do not want to struggle when setting off from a standstill.
Getting the Most from Your Gears and Sensor Together
The Mooncool POP’s Shimano 7-speed drivetrain adds another layer of control on top of the sensor system.
In torque mode, dropping to a lower gear increases your pedaling effort for the same speed, which means the torque sensor reads more input and the motor responds with more assist. It is a useful technique on climbs. Drop a gear, push harder, and the motor amplifies that effort instead of letting you grind. Shift up on flat sections, and the motor scales back accordingly.
In cadence mode, the gearing lets you control the level of assist indirectly. Pedaling faster in a higher gear increases your cadence, which tells the sensor to deliver more assist. Slowing your cadence in a lower gear reduces it. Once you get used to this, managing your assist level in cadence mode becomes intuitive without touching the display at all.
Ultimate Control with 180mm Hydraulic Disc Brakes
Whatever mode you are using, the Mooncool POP's brakes keep you safe. The front and rear 180mm hydraulic disc brakes need far less hand pressure to bite than mechanical alternatives, and they work consistently in wet conditions.
On top of this, the brake levers have a built-in power cut-off. This means the motor cuts power completely the moment you touch the lever. You’ll be especially thankful for this in cadence mode, where the motor delivers steady assist even when you ease off the pedals. The instant cut-off makes braking easy and immediate every time.
At that performance level, front and rear 180mm hydraulic brakes are confidence-inspiring. It is the right spec for the bike, and it gives you the confidence to push the motor hard knowing the stopping power is there when you need it.
Final Thoughts
The Mooncool POP gives you complete control over how you ride. Use the torque sensor for a natural, workout-friendly feel. Use the cadence sensor for effortless cruising. Twist throttle when you want the motor to do everything. All of it in one folding bike, at a price that makes this kind of sensor flexibility accessible to everyday riders.
