KAIJIELAISI V3 Electric Bicycle User Manual

Important Safety Information

FULLY CHARGE BATTERIES BEFORE FIRST USE: Batteries should be fully charged immediately upon receipt and after each use for the recommended charge times. Li-Ion (Lithium Ion) batteries typically require 4-6 hours for a full charge (2-3 hours for Via Urbano models).

It is recommended to consult a bicycle specialist if there are doubts or concerns regarding the experience or ability to properly assemble, repair, or maintain the bicycle. Additional warnings and cautions are provided in the assembly section of this manual.

With proper care and maintenance, a Currie Technologies Hybrid Electric Bicycle will provide ease of use and be enjoyable to ride.

Helmet Safety

HELMETS SAVE LIVES!!!

• ALWAYS WEAR A PROPERLY FITTED HELMET WHEN YOU RIDE YOUR BICYCLE.
• DO NOT RIDE AT NIGHT.
• CPSC records indicate that approximately 35% of bicycle-related deaths occur after dark.
• AVOID RIDING IN WET CONDITIONS.
• CPSC records show that about 65% of injuries happen to children under 15 years of age.
• RIDE ONLY WITH ADULT SUPERVISION.

Factors to Maximize the Range of Your Hybrid Electric Bicycle

The following points will help maximize the enjoyment and range from a new hybrid electric bicycle:

• Rider Input: The more the rider pedals, the further the distance traveled. Continuous riding, as opposed to frequent stopping and starting, will yield the greatest range possible.
• Elevation Gain: Flatter roads result in further distance traveled.
• Weather: Cold weather can adversely affect battery capacity.
• Wind: Traveling with a tailwind increases distance traveled, while traveling into a headwind decreases it.
• Terrain: Smoother terrain (roadways vs. fireroads, etc.) allows for further distance traveled.
• Rider Weight: A lighter rider results in less drain on the batteries and thus further distance traveled.
• Bicycle Maintenance: A properly maintained bicycle will yield the greatest range possible.
• Tire Pressure: Properly inflated tires have less rolling resistance and are easier to pedal.
• Batteries: Properly charged and maintained batteries will yield the greatest range possible. Batteries stored in cold areas (below 50°F / 10°C) will show reduced range. Batteries not kept in optimum condition will show reduced range and run time.

6. Handlebar installation is now completed.

Seat Post Installation

1. Locate the seat post clamp.
2. Open the lever and turn the nut to loosen the seat post clamp.
3. Insert the seat post into the seat tube.
4. Lock the clamp lever tightly to secure the seat post.

Front Wheel Installation

1. Turn the bike upside down for easier access.
2. Remove the red fork spacer (this is not a part of the bike).
3. Put the front wheel onto the fork.
4. Ensure the axle of the motor goes into the grooves of the fork.
5. Place the washers in the correct positions.
6. Tighten the nuts on both sides to secure the wheel.
7. Connect the inline connectors of the front motor cable.
8. Front wheel installation is now completed.

Pedal Installation

1. The pedal marked with the letter 'L' should be fixed on the left side. Turn the spanner counter-clockwise to fix the left pedal.
2. The pedal marked with the letter 'R' should be fixed on the right side. Turn the spanner clockwise to fix the right pedal.

Headlight and Fender Installation

1. Fix the headlight and front fender to the fork brace.
2. Connect the headlight cable.
3. Fix the front fender to the fork.

Rear Fender and Rack Installation

1. Fix the rear fender and rear rack to the frame.
2. Tighten the two upper bolts on both sides.
3. Tighten the two lower bolts on both sides.

Battery Installation

The bike is now ready to install the battery. Push the battery downward and lock it into place. Assembly is now completed.

Initial Power On

Turn on the battery first, then press the power button for 3 seconds to turn on the display. The red switch can be used to turn the front motor on or off.

Troubleshooting Display Error Codes

General Error Code Information

Except for communication errors, which are actively reported by the display, all other error codes shown on the display are reported to the display by the controller.

Possible Reasons for Error Codes:

1. Communication Error (1>): The display cannot detect a controller data reply within 10 seconds. Possible reasons:
   • The communication wire harness between the display and controller is not connected correctly or the wire harness is broken.
   • The protocol between the controller and the display does not match.
   • The communication wire of the display is burned.
2. Hall Sensor Failure (2>): Possible reasons:
   • The motor Hall sensor is damaged.
   • The Hall sensor wire is connected incorrectly or not properly.
3. Throttle Failure (3>): Possible causes:
   • The throttle is not in place.
   • The throttle is not connected properly.
   • The throttle is damaged.
4. Motor Phase Position Loss (4>): Possible reasons:
   • The motor phase position wire is not connected properly or correctly.
   • The motor phase position wire is short-circuited.
5. Brake Failure (5>): Possible reasons:
   • The brake is not in place.
   • The brake is damaged or not connected.
6. Controller Failure (6>): Possible reason:
   • The controller is damaged or MOS failure.
7. Abnormal Current (7>): Possible reason:
   • The controller is damaged or MOS failure.

Maintenance and Use Skills for Electric Bicycles

Power Assisted Mode

The power assisted mode, when matched with gear shifts, provides a labor-saving and power-saving riding experience. For riding on gentle slopes and good road conditions, it is recommended to use variable gears, specifically 7-6 high-speed gears, for optimal power-saving and speed ratio. For large slope road conditions, gears 4-7 are adopted for easier climbing. Riding with power assisted mode using speed shifting and climbing mode on flat roads will waste electric power and may result in a feeling of empty treading.

Influence of Temperature on Battery

Temperature significantly impacts the use of lithium batteries. While the impact at room temperature is generally not significant, the discharge capacity of lithium batteries changes when the temperature is higher than 40°C or lower than -10°C. For example, if the temperature is below 0°C in winter, the driving mileage will be shortened even with a fully charged battery, as the battery capacity can only be released by 60%-70%. Therefore, the driving mileage in winter will be much less than in summer.

Maintenance Methods

1. Winter Charging: When temperatures are low in winter, the battery should be placed indoors, and charging should also be carried out indoors. After the battery is fully charged, the charging time should be extended for another two hours.
2. Summer Charging: In summer, avoid exposing batteries to direct sunlight. Avoid charging the battery at high temperatures or immediately after use in high temperatures. Do not charge for too long. The battery needs to be charged for another one or two hours after the red indicator turns green.

Use on Different Road Conditions

The E-bike is not suitable for driving on roads with bad or steep conditions. If there are many uphill sections, the mileage from a single charge will be significantly less than on flat roads. When starting, going uphill, carrying a load, or driving against the wind, it is recommended to use the motor drive combined with human pedal power to ensure a longer working life for the battery and motor.

Avoiding Exposure to Sun and Rain

Although the electric bicycle has good waterproof performance and can be ridden in rainy and snowy weather, when passing through water puddles and other flooded roads, attention should be paid to the wading height. This height should not be higher than the motor to prevent damage from water inflow. Do not use a high-pressure water gun to wash the electric bicycle, as this can cause damage by water entering the electronic parts and accessories.

Frequent Braking

Frequent braking is associated with frequent start-ups, which leads to frequent large current discharge and power cut-off from the battery, impacting its life. Countermeasures include paying attention to safety while driving, maintaining a proper speed, and trying to avoid frequent braking.
