Electric bikes (eBikes) have revolutionised the way we travel, offering an efficient, eco-friendly, and enjoyable alternative to traditional transportation. A crucial component that defines the eBike riding experience is the pedal-assist system (PAS). This system uses either a torque sensor or a cadence sensor to measure your input and determine how much electric assistance to provide. Let’s explore the differences between these two technologies and how they can influence your ride.
A cadence sensor measures the rotation of the pedals to determine when and how much assistance to provide.
• How It Works: A magnetic disc on the crankshaft rotates past a sensor, signaling the motor to engage. Assistance begins as soon as you start pedaling.
• Key Benefits:
• Simplicity: Cadence sensors are straightforward and often found in entry-level eBikes.
• Affordability: Bikes equipped with cadence sensors are typically less expensive.
• Smooth Power Delivery: Ideal for casual riders, as the system provides consistent assistance regardless of the effort exerted.
• Best For: Leisure riders, commuters on flat terrain, and those new to eBikes.
A torque sensor measures the pressure or force you apply to the pedals, adjusting motor assistance proportionally to your pedaling effort.
• How It Works: Sensors within the bottom bracket or rear hub detect the strain on the pedals and relay this data to the motor controller.
• Key Benefits:
• Natural Ride Feel: Torque sensors mimic the sensation of riding a traditional bike, responding dynamically to your effort.
• Efficient Battery Use: Since assistance is based on effort, battery power is used more effectively.
• Precision Control: Perfect for riders who want a more intuitive connection between their input and the motor’s output.
• Best For: Fitness enthusiasts, riders tackling varied terrain, and those seeking a premium eBike experience.
| Feature | Cadence Sensor | Torque Sensor |
| Cost | More affordable | Typically more expensive |
| Response Time | Immediate assistance | Assistance builds gradually |
| Ride Feel | Consistent power delivery | Dynamic, natural ride |
| Battery Efficiency | Moderate | High |
| Terrain Suitability | Best for flat terrain | Ideal for hills and varied terrain |
Which Sensor Is Right for You?
Your choice between a cadence and torque sensor depends on your needs:
• Budget-conscious commuters might lean towards cadence sensors, as they provide reliable performance for everyday travel.
• Performance-focused riders who want a more natural and engaging experience will appreciate the responsiveness of torque sensors. Better suited towards steep hill climbing, ideal for eMTB’s and eCargo bikes.
