Read This First: Safety and Compliance with the Law

Congratulations on your purchasing of your new e-bike. Your new e-bike is an excellent piece of personal transportation equipment that will give you good service for many years.

Before you start using your e-bike, we want you to be aware of a few important points. Please read this section carefully.

• Observe Laws Regarding the Use of Battery-Operated Bicycles
  Your e-bike is designed and manufactured to meet safety requirements as a battery-operated bicycle. However, state and local laws governing the use of battery-operated bicycles on public roadways, parks, and other open areas may differ. Please check with your local authority before using your e-bike in public areas.
• Observe Laws Regarding the Use of Bicycles
  Note that all laws regarding the use of bicycles in public areas, such as those mandating the use of helmets and the use of infant seats, will automatically apply for e-bikes. Check with your local authority on what restrictions might apply.
• The Lithium-ion Battery of Your e-Bike
  Your e-bike is equipped with the latest battery technology. The lithium-ion battery is much lighter than lead- or nickel-based batteries that are being used in some older models.
• Your First Ride
  Please be VERY CAREFUL when you are ready to get on your e-bike for the first time because the e-bike moves significantly faster than a regular bicycle at active power-assisted mode. Take your e-bike to an area with a lot of open space before you start. Do not start pedaling hard as soon as you get on the e-bike (as you normally would with a regular bicycle), as the e-bike will accelerate under pedal-assist mode and you may be unprepared for the sudden increase in speed. However, after a few times, you will enjoy using the pedal-assisted function.

Model: S3

Please note that this is a general manual. So, the frame style of the electric bicycle (e-bike) that you have may differ from the picture shown in this manual.

Specifications

The following riding range assumes a 60kg (133 lb) load (rider weight + any carry-on weight) on a flat road, with the temperature 25-30°C, at the speed 20kmph(12mph):

• In Pedal Assist Mode 1: 70-90km (45-55 miles)
• In Hand Throttle Mode 1: 50-65km (30-40 miles)

The load, temperature, speed, and road condition will significantly affect the endurance. Other factors such as insufficient tire pressure, brake friction, frequent braking etc. will also affect the endurance.

Assembling Your New e-Bike

If you purchased your e-bike unassembled, please follow these instructions to assemble your e-bike under the guidance of an adult or a qualified technician. Assembly is quite easy as most of the parts are already assembled; you need only to put a few large pieces together to complete the job.

For more information, please refer to this website: www.geshengebike.com.

Name of each Part

Diagram showing the parts of the GESHENG S3 e-bike. Key components labeled include: LCD Display, Saddle, Battery Lock, Charging Port, Battery, Pedal, Controller, Speed Sensor, Chain, Rear Derailleur, Thickened Tire, Fork, Quick Release, Front Light, Disc Brake, Brake Caliper.

Assembly - Step 1: Attach the handlebar subassembly

Stand the main body of the e-bike on the kickstand. Stand up and lock the steering column. Insert the stem of the handlebar subassembly into the steering column. Ensure the fork points forward and orient the handlebar accordingly. Insert the stem fully and tighten using the quick lock.

Assembly - Step 2: Attach the Front Wheel Fender and the Front Light

Ensure the fork is pointing forward. Place the front light and front fender within the fork. Align the fender's screw hole with the bolt at the base of the steering column. Attach fender supports (if present) to the fork base using supplied bolts. Tighten all attachment points with multi-tools.

Assembly - Step 3: Attach the Front Wheel and Adjusting the Front Brake

Ensure the fork is pointing forward. Remove the protective bar from the front fork. Place the front wheel into the fork, ensuring the brake disc aligns with the brake block. Seat the axial stem into the fork's receptacles and tighten nuts with multi-tools. Verify the front wheel spins freely without wobbling. Re-position and re-tighten if necessary.

Brake Testing

Test the brake by lifting the front of the e-bike and setting the wheel in motion (turn it) and apply the brake at the handlebar to stop it. If you could not set the wheel in free motion, or if you could not stop it by applying the brake, you need to re-adjust by increasing or decreasing the clearance.

[CAUTION]: Do not operate the e-bike until you are satisfied that both the front and rear brakes are operational.

Assembly - Step 4: Installing the Seat and Pedals

Insert the seat pedestal stem into the seat column and tighten with the lever. Attach pedals to the crank arms, noting left and right differences, and tighten with multi-tools. Inflate tires to proper pressure. Check all tightening points. Take a short ride and adjust handlebar height and seat tilt for comfort.

Assembly - Step 5: Charging the Battery

Connect the charger's power cord to a wall outlet. Insert the smaller cable into the battery's charging terminal. The charger LED will be RED during charging and GREEN when complete. Ensure the battery is turned OFF while charging. Disconnect the charger when green and replace the rubber cap. When the battery is installed and turned ON, the display shows the charge level.

You are now ready to start using your e-bike.

Operating Your New e-Bike

The method to turn on the bike is:

1. Twist the battery lock counterclockwise to the end to turn on the battery.
2. Press the power button on the left handlebar until the display lights on.
3. Ride the bike and twist the throttle bar or pedal the bike; the bike will move. You can change the power level with control buttons: level 1 is the slowest and level 3 is the fastest, level 0 is human model.

Your e-bike is driven by a motor embedded in the hub of the rear wheel, powered by a battery. The amount of power delivered to the motor, and hence the accelerating force, is controlled by you via the power-assisted mode or full power mode you choose.

You can configure the e-bike to operate in pedal-assist-only-mode or full power mode (check local laws to ensure full power mode is permitted), where you can also use the hand throttle to deliver power to the motor.

Your First Ride (Reprinted from Safety and Compliance)

Please be VERY CAREFUL when you are ready to get on your e-bike for the first time because the e-bike moves significantly faster than a regular bicycle at active power-assisted mode. Take your e-bike to an area with a lot of open space before you start. Do not start pedaling hard as soon as you get on the e-bike (as you normally would with a regular bicycle), as the e-bike will accelerate under pedal-assist mode and you may be unprepared for the sudden increase in speed. However, after a few times, you will enjoy using the pedal-assisted function.

Pedal-Assisted

You must turn on the battery to use the e-bike in pedal-assisted mode. In this mode, power assist is triggered when you pedal forward and stops when you stop pedaling (sometimes with a slight delay). Power assist happens as long as you pedal; you do not need to pedal hard. Apply a light, continuous force to the pedals to maintain current flow. When you apply a brake, power assist will automatically stop, allowing the e-bike to slow down and stop. Power assist will turn itself off when the e-bike reaches the maximum speed for the selected power level.

Use the gear shifter at the handlebar to set gears appropriately according to road conditions. You will find that you need to exert less effort, and the e-bike travels faster and more steadily.

Cruise Control

Cruise Control will be triggered when holding the thumb throttle for 8 seconds, and it will be released by braking, pedaling, or throttling.

Hand Throttle Control

In hand throttle mode, power assist is determined by the throttle switch controlled by your right hand. Twist the throttle from its resting position; the farther you twist, the more power is delivered to the motor. To slow down, release the throttle to its resting position and apply brakes if necessary. You do not need to pedal when using the hand throttle, but pedaling can help conserve battery life.

Charging Your e-Bike Battery

Your e-bike battery is a lithium-ion battery requiring specially designed chargers. Never use a substitute charger. Using an unsuitable charger can result in overheating, fire, or explosion. Ensure charger voltage matches battery voltage. If your charger is lost or damaged, contact your dealer for a replacement.

Charge your battery while the e-bike is not in use. Turn off the battery before charging. You may charge the battery while it is mounted on the e-bike or after it has been removed.

Do not place the charger or battery near flammable substances during charging. Charging should not be done near infants and small children. Remove valuable objects from the vicinity of the battery while charging. Do not charge unattended for long periods. For safety, it is recommended not to charge in the middle of the night.

To maintain battery life, do not charge until the battery is completely discharged. Start charging when the power is less than 20 percent. If the battery will not be used for an extended period, charge it fully and recharge it every month. If not used for several months, the battery may self-discharge and become unable to charge.

Charging time depends on the battery's current charge level. A completely discharged battery takes about 6 hours to fully recharge. When fully charged, the charger LED changes from RED to GREEN. Disconnect the charger at this point. Do not leave the charger connected for extended periods after charging is complete (overnight charging is acceptable).

It is normal for the charger and battery to be slightly hot while charging.

Removing the Battery from the e-Bike

The battery is an important and costly part of the e-bike, designed to be locked with a key for theft prevention. For added security, you can remove the battery when the e-bike is parked unattended. You may also need to remove it for charging at a location where you cannot park the bike.

The method to remove the battery is:

1. Open the cap of the charging port and fold the bike.
2. Insert the key into the battery, press and hold the key slightly, then twist clockwise to the end. (Note: You cannot remove the battery until the lock bar withdraws completely into the battery).
3. Slide off the battery. The battery is heavy; handle with care to avoid dropping it.

Maximizing the Riding Range

Many factors affect electrical energy usage and riding range:

• Fully charge the battery before a long journey.
• Rough road conditions and hilly terrain consume more energy.
• Frequent changes in speed consume more energy.
• Carrying more weight on the e-bike consumes more energy.
• Keeping tires properly inflated and the e-bike clean and well-lubricated saves energy.
• Ensure both wheels move freely when brakes are not applied; check brake adjustments frequently.
• Pedaling as you ride consumes less electrical energy and increases the riding range.

When the battery is turned off, your e-bike functions as a regular bicycle. For very long journeys on level or downhill sections, consider turning off the battery and pedaling as a regular bicycle to conserve electrical energy.

Care and Maintenance for Your New e-Bike

In general, care for your e-bike as you would a regular bicycle: keep it dry, clean, and ensure moving parts are well-lubricated. Avoid parking your e-bike in exposed areas whenever possible.

Check the effectiveness of the brakes before each use.

For your e-Bike, you should also take note of the following:

• Your e-bike is designed for regular country road use for a single person. Using your e-bike for extreme maneuvers, such as extreme off-road use, jumping, or carrying excessive loads, will damage the e-bike and could cause serious injury.
• Do not use high-pressure water streams to clean your e-bike, as water might seep into the motor or wiring compartment, causing rusting of electrical parts or short circuits.
• Avoid parking your e-bike outside during rain or snow. After riding in rain or snow, bring the e-bike inside and use a clean, dry towel to eliminate any wetness.
• Be sure you do not lose both keys. If you lose one key, make a copy as a backup. If you lose both keys, you will be unable to remove the battery from the e-bike.

Special Care for the Battery and the Charger

• Use only the supplied charger to charge your battery. Do not use an unauthorized substitute. If your charger is lost or damaged, contact your dealer to order a replacement.
• Do not open or alter the battery or the battery charger. Do not place the battery near fire or corrosive substances. Do not immerse in water or other liquids.
• Avoid subjecting the battery to high temperatures, such as direct sunlight, for prolonged periods.
• Do not connect (short circuit) the two poles of the battery.
• After significant use, your battery's charge holding capacity will decrease. If your battery does not hold sufficient charge even for short trips, contact your dealer for a replacement. Under normal use, the battery will undergo approximately 500 charging and discharging cycles.
• If the battery will not be used for an extended period, charge it fully and recharge it every month. Store it in a cool place.
• Your e-bike battery is engineered for high capacity and long useful life. We do not recommend using it to power other electrical devices. Improper use of the battery can damage it, shorten its useful life, and may cause a fire or an explosion.
