Safety Precautions Before Riding

• ⛑️ Wear a Helmet: Always wear a helmet when riding your e-bike.
• ? Key Management: Keep the key in a safe place. Losing the key will prevent the bike from being turned on or the battery from being replaced.
• ? Battery Charge: Ensure the battery is fully charged before riding.
• ⚖️ Obey Road Laws: Be aware of and adhere to all local road laws.
• ? No Impairment: Do not ride your e-bike under the influence of drugs or alcohol.
• ? Respect Pedestrians: Always show consideration for pedestrians.
• ?️ Avoid Wet Conditions: Riding in wet conditions increases the risk of falling and can damage electronic equipment, potentially voiding the warranty.
• ? Age Restriction: This electric bicycle is intended for adults aged 18 years and older. Minors are not recommended to use it.
• ? Installation: Please refer to the installation video and ensure the electric bicycle is installed correctly, checking for loose screws.

Battery Charging and Range Maximization

Battery Charging

Before First Use: Fully charge the battery. Please pay attention and remain vigilant to avoid fire when charging. Charge the battery indoors in dry spaces, away from extreme temperatures, dirt, debris, or flammable items. The charger automatically stops when the battery is full.

If you have doubts about assembly, repair, or maintenance, consult a bicycle specialist.

Factors to Maximize Range

• Rider Input: More pedaling by the rider increases distance traveled. Continuous riding yields greater range than frequent stopping/starting.
• Elevation Gain: Flatter roads allow for longer distances.
• Weather: Cold weather can adversely affect battery capacity.
• Wind: A tailwind increases distance; a headwind decreases it.
• Terrain: Smoother terrain (e.g., roadways vs. fireroads) allows for longer distances.
• Rider Weight: Lighter riders result in less battery drain and longer range.
• Bicycle Maintenance: A well-maintained bicycle offers greater range.
• Tire Pressure: Properly inflated tires have less rolling resistance, making pedaling easier.
• Battery Condition: Properly charged and maintained batteries yield the greatest range. Batteries stored in cold areas (below 10°C / 50°F) will show reduced range. Batteries not kept in optimum condition will also have reduced range and run time.

Operation and Controls

LCD Display and Instruments

The LCD display provides real-time information including speed, battery status, PAS level, mileage (ODO/TRIP), and error codes. Key controls are located on the handlebars.

Main Display Elements:

• Electricity/Battery Status: Visual indicator of remaining battery power.
• Voltage: Displays battery voltage.
• Speed: Shows current speed (KM/H or MPH).
• PAS: Pedal Assist System level (0-5).
• ODO: Total mileage from factory.
• TRIP: Mileage since last reset.
• Average Speed: Current average riding speed.
• Top Speed: Current maximum riding speed.
• Gear: Indicates the current gear selection (e.g., SHIMANO).
• Indicators: Icons for cruise control, brakes/breakdowns, etc.

Operation Instruments:

• Switches of Headlights and Horn: Controls for lights and horn.
• LCD Control Buttons: Typically '+' and '-' buttons for adjusting settings and assist levels, and a power button.
• LCD Display: The main screen showing all information.
• Gear Shifter: For changing gears (e.g., SHIMANO).
• Twist Throttle: For electric-only propulsion.
• Key: Ignition key for powering the bike on/off.

Riding Modes

• Pure Electric Mode: Uses throttle only for propulsion. Recommended for flat roads.
• Pedal Assist System (PAS) Mode: Motor assists pedaling. You use your feet to pedal and help the motor.
• Pure Human Riding: Standard bicycle pedaling without electric assistance.

Cruise Control System

In pure electric riding mode, a long press of the '-' button (for 5 seconds) can activate cruise mode, indicated by a "Cruise" sign on the display. Applying the brake cancels cruise mode. Use cruise mode only on good road conditions with minimal pedestrian and vehicle traffic.

Power On/Off

Power On: Press and hold the "POWER ON/OFF" button for 5 seconds until the display lights up. Ensure the battery is locked and the key is inserted/turned if applicable.

Power Off: Press and hold the "POWER ON/OFF" button for 5 seconds.

Selection of Assist Levels

Short press the '+' or '-' keys to switch between assist levels, typically ranging from 0 to 5 gears. Gear 1 is the lowest power, and Gear 5 is the highest. The specific values for each gear can be adjusted in the settings interface.

Assisted Pushing

Long press the '-' key for 3 seconds to engage the power-assisted pushing mode. The e-bike will move at approximately 6 km/h. Long press for another 3 seconds or squeeze the brake to stop this mode.

Dual-Drive Mode

Press the power button twice to switch between drive modes: Rear-wheel Drive or Dual Drive.

Speed Display

When operating normally, the current speed is displayed. Short press the power key to cycle through AVG (Average Speed) and MAX (Maximum Speed). Select AVG or MAX using the '+' and '-' keys. Confirm the selection by clicking the power key again or waiting 8 seconds.

Battery Power Display

The battery power is shown based on the set battery voltage. If the model supports BMS (Battery Management System), the battery power display is subject to BMS readings, and the instrument's estimated power may become invalid.

Mileage Display

The display shows total mileage (ODO) from the factory and single-ride mileage (TRIP). Short press the power key to switch between ODO and TRIP units. Select ODO or TRIP using the '+' and '-' keys. Confirm by clicking the power key again or waiting 8 seconds. The TRIP mileage resets automatically after each startup.

Error Codes

When a fault occurs in the electronic control system, a fault light illuminates, and a code is displayed at the speed position.

• 06: Under-voltage Fault (Battery Discharge): Indicates the battery voltage is too low.
• 07: Motor Fault: Possible causes include a loose motor wire plug or a damaged motor.
• 08: Throttle Fault: Issues may arise if the throttle is not in its original position before startup, if the plug is loose, or if the throttle is damaged.
• 09: Controller Fault: Indicates the controller is damaged.
• 10: Communication Receiving Fault: Potential causes include plug condition, controller damage, damaged instrument power lock, or short circuits of 5V devices at the controller end.
• 11: Communication Sending Fault: Possible causes include plug condition, instrument damage, or controller damage.

Maintenance and Use Skills

1. Influence of Temperature:
   • Temperature impacts lithium battery performance. At temperatures above 40°C or below -10°C, discharge capacity changes.
   • In winter (below 0°C), battery capacity release may be limited to 60%-70%, reducing driving mileage.
   • Maintenance: In low temperatures, store and charge batteries indoors. After full charge, extend charging time by two hours.
   • In summer, avoid sun exposure and charging at high temperatures. Do not charge immediately after high-temperature use or for too long. Charge for an additional one to two hours after the red indicator turns green.
2. Use on Different Road Conditions:
   • The e-bike is not ideal for bad or steep roads. Uphill riding significantly reduces mileage compared to flat roads.
   • When starting uphill, carrying loads, or riding against the wind, use the motor drive combined with human pedaling to prolong battery and motor life.
3. Avoid Exposure to Sun and Rain:
   • While the e-bike has good waterproof performance, avoid riding through water puddles or mud that reach higher than the motor to prevent water damage to electronics.
   • Do not use a high-pressure water gun for cleaning to prevent water ingress.
4. Frequent Braking and Start-up:
   • Frequent braking and start-ups lead to high current discharge and battery power cut-offs, impacting battery life.
   • Countermeasures: Drive safely, maintain a proper speed, and try to avoid frequent braking.
5. Regular Maintenance:
   • Regularly check and tighten all main screws.
   • Add lubricating oil as needed.
   • Keep the bicycle clean to prevent rusting.
   • Avoid prolonged exposure to sunlight and rain.
