Usage Features

Control Parts Functionality:

• Left Brake Lever: Controls the rear brake and acts as a brake power-off control switch. Gripping it activates the rear brake, stops the rear wheel, illuminates the brake light, and cuts power to the motor for dual safety.
• Light Switch (Headlight and Dimmer): In the evening, the first-gear position turns on instrument and tail lights. The second-gear position activates both high and low beams.
• High- & Low-Beam Light Switch: Toggles between weak (LO) and strong (HI) headlight beams. For safety, the LO position is recommended when facing oncoming vehicles at night.
• Turn Signal Switch: Used for indicating turns or lane changes. Setting to R (right) or L (left) flashes corresponding front and rear turn signals. The middle position is Off, and pressing inward returns it to Off.
• Speedometer: Displays driving speed (km/h) and distance traveled.
• Energy Meter: Shows battery voltage level (H for high, L for low).
• Indicator Lamps: Pointed lamps indicate turn signals; the middle lamp indicates high/low beam.
• Right Brake Lever (Front Brake Lever): Controls the front wheel brake and acts as a brake power-off control switch. It is recommended to use both front and rear brake levers for emergency braking to prevent skidding.
• Rearview Mirror: Essential for checking surroundings to ensure driving safety during turns or overtakes.
• Speed Governor Handle: Controls motor RPM and driving speed. Gentle inward rotation increases speed.
• Master Lock (Electric Lock): Controls the power supply to the vehicle and controller. The vehicle will not operate until the lock is enabled. In case of malfunction or uncontrolled motor speed, setting the switch to OFF prevents further operation and accidents.
• Horn Switch: Activates the horn when pressed.
• Parking Lock: Engages after stopping. Grip the left brake lever, hold the parking lock upwards, then release the brake lever to activate. Adjustment of the rear brake may be needed if the parking lock is ineffective due to worn brake shoes.
• 3-Speed Switch (Speed Regulation Switch): Designed for special populations. Low-speed mode: 9km/h; Medium-speed mode: 15km/h; High-speed mode: 25km/h. Low-speed mode is recommended initially for safety.
• Reversing Switch: Allows reversing by rotating the speed governor handle when set to the O position. Reversing speed is limited to 5km/h.
• Remote Control Switch (Alarm Switch): Optional, for remote power on/off.
• Player's Switch (MP3 Player): Optional, supports USB flash drives, SD cards, and radio.
• Player Speaker: Used for MP3 player amplification.
• Circuit Breaker (in saddle support): Controls the main switch. Must be closed for riding and set to OFF for battery charging to prevent controller damage from high voltage.
• Charging Receptacle (at lower seat end of front cover): Battery charging input socket. Must not be covered to avoid sparking accidents.

Driving Cautions:

• Start by inserting the key and turning it clockwise.
• Accelerate gradually by slowly turning the governor handle inwards. Release the handle to reduce speed or cut power.
• Operate at low speed on non-motorized vehicle lanes.
• Brake power-off protection: Using either brake lever cuts motor power.
• To restart after stopping, reset the governor handle then slowly accelerate.
• Avoid abrupt acceleration when driving uphill or against wind to prevent motor and battery overload.
• Avoid driving through water deeper than the rear wheel centerline to prevent motor and battery damage.
• Do not operate both the governor handle and brake lever simultaneously to prevent motor overload.
• Avoid bumpy or steep roads and heavy vibration to prevent poor electrical contact. Drive at low speed on such roads.
• Reduce braking frequency and avoid frequent starts.
• Reduce speed on bumpy, muddy, or heavy traffic roads.
• Do not turn the governor handle instantly to accelerate.
• The differential motor for the rear axle requires gear oil lubrication, which should be changed every three months.

Battery Cautions:

• Uses sealed serviceable lead-acid batteries with large capacity, long life, and good maintainability.
• Batteries are consumables; proper use and quality batteries can suppress capacity deterioration.
• Keep batteries fully charged. Charge monthly if stored for long periods. Never store in an exhausted condition.
• Monitor battery case temperature during charging; if too high or if the indicator doesn't change color, stop charging and seek inspection.
• Battery capacity reduces by 20-30% below 15°C.
• Never mix batteries of different parameters in a battery pack.
• Keep batteries away from flames, heat, alkaline materials, and direct sunlight.
• Do not charge immediately after use on hot summer days. Charge in a warm indoor environment below 0°C.
• To maximize range: drive at low speed, charge frequently, and use the low-speed range as much as possible.

Adapter and Battery Charging Cautions:

• The charger has a hi-tech CPU IC with optimized programs for electric bicycle/vehicle batteries, using random process control for optimal charging.
• In regions with unstable grid voltage (fluctuation exceeding AC220V±20%), use an AC regulator. The charger does not require earthing.
• Charge the battery while in service if possible. The charger indicator turning green signifies full charge and float-charge condition (no power cut-off needed). Orange indicates partial charge.
• Never turn off the air switch on the vehicle during charging.
• Connect the charger output plug to the vehicle's charging receptacle, then plug the charger into an AV220V power socket.
• Red indicator: constant-current charging. Orange: 90% charged. Flashing green/orange then steady green (after ~1 hour): 100% charged. Further charging enables on-line maintenance.
• Do not place items on the charger or battery case during charging to facilitate ventilation.
• Avoid rough bumps or impacts to the charger.
• Protect the charger from liquid or metal chip ingress.
• The charger generates heat; do not place flammable materials underneath or cover it. Use in a well-ventilated area.
• If an odor or high temperature (>65°C) is detected, stop charging and seek service.
• On-line maintenance requires longer charging time; weekly long-time charging is recommended.
• The charger adapts to different battery manufacturers and temperatures, regulating charging voltage for full charge without damage and extending battery life.
• If the charger indicator doesn't change color for over 12 hours, remains red, and the battery produces excessive heat, stop charging and seek inspection.

Maintenance Features

Daily Inspection and Adjustment:

• Brake System: Check functionality of left and right brake levers, automatic power cut-off upon braking. Ensure safe stopping distance (5 meters from top speed). Adjust brakes or replace pads if needed. Check front and rear wheels for normal rotation without friction when unloaded. Adjust brake drum cover set screws so the brake lever grips at 1/2 travel.
• Other Safety Systems: Check tire pressure (standard: 300kPa/3.0kpa/cm²). Inflate if inadequate. Check left and right turn signals and tail light. Check power-off brake lever.
• Driving Cautions: Check for smooth vehicle start, consistent driving speed, free and easy handle turning, flexible and reliable brakes, absence of abnormal sounds from wheels, proper function of turn signals, horn, headlights, tail lights, and instrument lights. Check for loose fastening screws, bolts, and nuts. Check free travel of brake cables. Replace immediately if any abnormality.
• Simple Adjustment: Brake lever should engage at 1/2 grip. Maintain appropriate tire pressure.

Inspection and Maintenance Schedule:

• Daily: Inspect if rotating and steering parts of the handle are loose or worn.
• Every 60 days: Inspect if tire pressure is appropriate and tire shoe is worn. Inspect if the rim swings or is distorted. Inspect if the gearbox oil has been replaced. Inspect if the brake is good. Inspect if the horn sounds well. Inspect if the charger and cables are worn.
• Every 180 days: Inspect if rotating and steering parts of the handle are loose or worn. Inspect if tire pressure is appropriate and tire shoe is worn. Inspect if the rim swings or is distorted. Inspect if the gearbox oil has been replaced. Inspect if the brake is good. Inspect if the horn sounds well. Inspect if the charger and cables are worn.
