The Pedal Assist System (PAS) activates the motor when the rider pedals.
Which SUPER73 Models have a PAS System?
| Series | Model | PAS System? |
| R-Series | All Models | Yes |
| S-Series | All Models | Yes |
| Z-Series | SUPER73-Z MIAMI | Yes |
| SUPER73-ZX | Yes | |
| SUPER73-Z1 | No |
How to Change PAS Level vs. Class Modes
- Using the display (and the app, in the bottom right corner), you can change the level of PAS, which corresponds to the percentage of pedaling assistance you will receive.
The PAS levels are how much power you’ll get from the motor to reach the maximum speed of the mode your bike is set to.
PAS 1= 25%, PAS 2= 50%, PAS 3 = 75%, PAS 4= 100%*
PAS System Types (2)
- Cadence Sensor: measures if you are pedaling.
- Torque Sensor: measures how much pressure you are applying on the pedals.
Cosmetic Differences
- The Cadence Sensor has a slick knob cover on the left side of the bottom bracket with an LED light that switches "ON" red when the pedals are engaged.
- The Torque Sensor has a ribbed knob cover on both sides, located inside the bottom bracket.
How Each Sensor Engages PAS
- The Cadence Sensor uses a magnet within the crank located on the bottom bracket of your SUPER73. The motor will activate when you start pedaling and deactivate when you stop pedaling. The motor can also stop assisting if the rider reaches the maximum speed of the current "mode" chosen. This sensor works more or less like a switch.
A Cadence Sensor-equipped bike will always receive maximum assistance from the start. It is important to keep in mind that for a smooth assist at a top speed, the sensor needs to continuously record movement; Meaning that pedaling faster won’t increase the amount of assistance. A constant pedal stroke, “cadence”, will keep triggering the sensor, therefore the assist. - The Torque Sensor uses a precision strain gauge. It will measure the actual force put onto the pedals. The more force you use to pedal, the more the motor will assist. The maximal assist is determined by the mode and level you are in. If you pedal with lesser force, the motor assist will be low. It makes this adjustment in real-time, so it is technically amplifying your input. Because it is continuously analyzing effort rather than just checking for rotation at a handful of intervals. A torque sensor is able to adjust the motor’s assistance more dynamically and intuitively. It responds proportionally to the effort you put into the pedals.
*these PAS levels apply to NEW Gen Bikes (Adventure Series, S2, R-Series, ZX, Z Miami). Does not apply to S1 model.
