Safety Information
Warning!
· Install and adjust this bicycle ONLY in accordance with these instructions. Read them completely prior to installation and use. Contact customer service if any point is unclear.
· ALWAYS obey all applicable local and national laws and regulations while riding. Do not ride this bicycle in any area prohibited to electric bicycles. Always wear your helmet and other required protective gear. Always maintain your reflectors and other required safety equipment.
· Check whether the brakes function well using the brake levers before riding. Even after power is cut to the motorized wheel, the inertia of the bike will often require active braking power.
· ALWAYS ensure all fasteners and components are intact and securely tightened before and after every use.
· 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 03, 06, or 07 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.
· Disconnect the battery from this bicycle before any cleaning, servicing, and storage.

FAQ and Suggest Solution

FAQ and Suggest Solution

Question
Battery cannot be charged normally Battery indicator light is abnormal

Suggest Solution
(1) First confirm that the charging method is correct. The correct method to charge the battery 1.The plugs at both ends of the charger should be connected to the battery first, and then to the power supply. 2. If the green light is displayed after the charger is connected for the first time , it may be that the power supply is not connected properly. Try reconnecting, the red light shows that it is charging normally. 3.It is normal for the battery indicator to show 3 green and 1 red when it is fully charged. (2) If confirm that the charging method is correct and battery still won’t charge Provide video to sellers to judge specific problems: What the video needs to show: please bring the battery to a brighter space, then plug the charger into the socket.Take a video of the charging process including the battery and the charger. Seller need to observe the charger indicator and battery indicator status.So that judge the specific problem based on how the charger and battery react when charging
