How to Switch Between Torque Sensor and Cadence Sensor
Sensor Mode Switching Method
Condition: The bike must be powered ON
-
Turn on the e-bike and confirm the display is active
-
Quickly press the “M” button three times
-
Each triple press switches the pedal assist system between:
-
Torque Sensor Mode
-
Cadence Sensor Mode
-
No menu access is required.
No app connection is required.
The switch can be completed while the bike is stationary.
Torque Sensor Mode
-
Motor assistance responds directly to pedaling force
-
Assistance output increases immediately with stronger rider input
-
At low speeds or during initial starts, stronger pedal force may result in more noticeable forward acceleration
For smoother starts, riders are advised to apply pedal force gradually when starting from a stop.
Cadence Sensor Mode
-
Motor assistance responds to pedaling rotation
-
Assistance output remains consistent while pedaling
-
Provides a steady and predictable riding rhythm
How to Shift Gears on CYCROWN ROMA (Shimano 8-Speed)
The ROMA is equipped with a Shimano 8-speed rear drivetrain, operated via the right-hand shifter.
-
Press the inner lever → shift to a higher gear
-
Press the outer lever → shift to a lower gear
Shift one gear at a time and slightly reduce pedaling force during shifting.
Front Suspension Lockout Adjustment
The CYCROWN ROMA features a front suspension fork with lockout adjustment.
-
The suspension can be locked or unlocked using the adjustment control on the fork
-
When locked, the fork remains firm to reduce movement during pedaling
-
When unlocked, the fork absorbs bumps and uneven terrain for improved comfort
Locking the suspension is suitable for smooth roads and steady cruising, while unlocking it improves control and comfort on rough or uneven surfaces.
