• DO NOT ride this bicycle if any part is damaged or malfunctions. Repair or replace worn and broken parts before further use.
• Pay attention to the remaining power before setting out and during use. Recharge your battery as needed to ensure it never runs out of power at a moment where you are taken by surprise.
• DO NOT allow children or persons unfamiliar with these instructions to operate this bicycle without strict supervision.
• DO NOT wear loose footwear or clothing that may become caught in the wheels or any other moving parts.
• It is recommended that you not ride your bike fast when getting started. This can be ensured by setting the bike’s maximum speed limit low until you are fully familiar with your new electric bike and its controls.
• ALWAYS be alert for people, animals, or any obstacles that may appear in front of you while riding your bicycle. Be aware that pedestrians and drivers may not expect the speed or responsiveness of your bike. Adjust your behavior accordingly. It is advisable to install warning devices to draw their attention, but always be ready to turn safely out of their way if needed. Do not focus on the LCD display for extended periods of time while riding.
• NEVER ride at a speed where your stopping distance exceeds your visibility. We do not recommend that you ride your bicycle at night or in an environment with poor visibility. If you have an emergency that makes it necessary to do so, keep your light on and limit your speed appropriately.
• DO NOT get the battery, its charger, or its power cord wet or operate them with wet hands.
• NEVER use the pedal assist system (PAS) or timed shutoff in any situation, road condition, or terrain where doing so might impair your control of your bicycle.
• NEVER adjust 02, 04, or 05 on the LCD display panel. Adjustment of these parameters should only be made when using the display with other compatible motorized wheels of differing voltage, diameter, or magnet arrangements. In any other case, any adjustment of these parameters should be undone immediately and the original settings restored before any further use of this bicycle.

Operation

Riding with Throttle Control

1. Hold until the display panel turns on.
2. Push the throttle lever to activate the motorized wheel.
3. To speed up, push the throttle lever further. The bicycle will not exceed the maximum speed limit you have set on flat pavement but may do so on slopes.

To slow down, ease the throttle lever back and/or press your brake levers. Pressing either brake lever completely will cut off all power from your battery to the motorized wheel, temporarily leaving it in neutral. Release the brake to restore power at its previous level.

To toggle to pedal assist control during a ride, fully release the throttle lever while pedaling your bike.

4. To stop your bicycle, release the throttle lever completely and apply your brakes as needed.
5. To turn off the motorized wheel, release the throttle and brake levers while the bike is completely stopped. Hold until the display panel turns off.

Riding with Pedal Assist Control

1. Make sure the throttle lever is fully released.
2. Turn the pedals on your bicycle once. The pedal assist system (PAS) will activate and turn the wheels using the motor’s power immediately, allowing the bike to reach the maximum speed at the current level.
3. Turn off the pedal assist system by turning the throttle or pressing either brake lever. The bike will default to throttle control or neutral.
