4.2 Pedal Assist (PAS) and Throttle Modes

The bike offers multiple pedal assist levels, which can be adjusted via the display controls. The throttle provides power on demand without pedaling.

4.3 Unlocking Maximum Speed

To unlock the maximum speed, ensure the display is off. Twist the throttle to the bottom while simultaneously squeezing the right brake lever and holding it. Turn on the display, wait 5-8 seconds, then release the throttle and brake. The speed limit will be removed, and you can set the gear to the 5th gear (highest) to reach maximum speed.

4.4 Lights and Horn

The bike is equipped with an LED headlight and taillight for visibility. Use the handlebar controls to activate the lights and horn as needed.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your electric bike.

5.1 Battery Care

Keep the battery charged, especially during long periods of storage. Store the battery in a cool, dry place. The battery can be removed for charging or storage.

5.2 Brake Adjustment

Regularly check your mechanical disc brakes for proper function. If you hear a "rustling" sound from the wheels, the brake pads may need adjustment. Slightly loosen the two screws on the brake clamp, adjust the clamp so it does not contact the brake disc, then tighten the screws.

5.3 Suspension Fork Adjustment

The adjustable suspension fork can be locked or unlocked depending on the terrain. Lock the fork for efficient pedaling on smooth surfaces and unlock it for better shock absorption on rough terrain.

5.4 Tire Pressure

Maintain recommended tire pressure for optimal performance and safety. Refer to the tire sidewall for specific pressure ranges.
