Safety and Compliance with the Law

Congratulations on your purchase 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.

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 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, as 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.

Assembling Your New e-Bike

If you purchased your e-bike unassembled, follow these instructions under the guidance of an adult or a qualified technician. Assembly is easy, as most parts are pre-assembled; you only need to connect a few large pieces.

For more information, please refer to: www.engwe-bikes.com.

Check that the Package is Complete and Undamaged

Your e-bike comes in a carton containing the following:

• The main body of the e-bike (frame, rear wheel, gear and chain, rear brake, battery in frame, rear fender).
• The handlebar subassembly with battery keys. It is connected to the main body by brake cables and electrical wires. The handlebar has brake levers and gear control. The right handle includes controls for throttle mode, power-assist, and a display panel.
• The Seat, attached to its pedestal stem.
• The front wheel.
• The front wheel fender with supports.
• The front light, connected to the main body by an electrical wire.
• Tools and other parts: One multi-tool, one charger, a pair of foot pedals. These are contained in a separate box.

Assembly Steps:

Step 1: Attach the Handlebar Subassembly

Stand the main body of the e-bike on its kickstand. Stand up and lock the steering column. Insert the handlebar stem into the steering column. Ensure the fork (which holds the front wheel) points forward and orient the handlebar accordingly. Insert the stem fully and tighten from the top using the quick lock.

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

Ensure the fork from the steering column points forward. Place the front light and front fender within the fork. Locate the small projection with a screw hole at the top of the fender and fit it to the bolt at the base of the steering column. Attach the supports (one on each side) to the base of the fork using two small bolts. Use the multi-tool to tighten all three points.

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

Ensure the fork points forward. Remove the protective bar from the front fork. Place the front wheel within the fork and the brake disc within the brake block. Seat the axial stem properly in the receptacles at the tips of the fork and tighten the nuts with the multi-tools. Ensure the front wheel moves freely and does not wobble. Reposition and re-tighten if necessary.

Test the brake by lifting the front of the e-bike and spinning the wheel. Apply the brake at the handlebar to stop it. If the wheel does not spin freely or cannot be stopped, re-adjust the clearance.

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

Step 4: Installing the Seat and Pedals

Insert the seat pedestal stem into the seat column of the main body frame and tighten using the built-in lever. Attach a pedal to each side of the crank and tighten with the multi-tools. Inflate tires to proper pressure.

At this point, your e-bike is a functional bicycle without battery power. Check all tightening points. Take a short ride and adjust handlebar height, seat height, and tilt for maximum comfort.

Step 5: Charging the Battery

Remove the charger, attach the power cord, and plug into a wall outlet. Insert the smaller cable's plug into the battery's charging terminal. The charging terminal is on the side of the battery opposite a hole on the frame. The charger LED glows RED while charging and GREEN when complete. Turn the battery OFF while charging. Disconnect the charger when the LED turns Green and replace the rubber cap on the terminal. If the battery is installed and turned ON, the display panel will show the charge level.

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

Operating Your New e-Bike

To turn on the bike:

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 up.
3. Ride the bike and twist the throttle bar or pedal. The bike will move.

You can change the power level with control buttons: Level 1 (slowest) to Level 5 (fastest). Level 0 is the human model (no motor assist).

Your e-bike is powered by a motor in the rear wheel hub, fed by a battery. Power delivery and acceleration are controlled by your choice of power-assisted mode or full power mode.

You can configure the e-bike for pedal-assist-only mode or full power mode (check local laws for full power mode legality). You can also use the hand throttle for motor power.

Your First Ride

(Reprinted from Safety and Compliance section) Please be VERY CAREFUL when riding for the first time, as the e-bike moves significantly faster than a regular bicycle in power-assisted mode. Use an open space. Do not pedal hard immediately; the e-bike accelerates quickly. You will enjoy the pedal-assist function after a few rides.

Pedal-Assisted Mode

You must turn on the battery to use pedal-assisted mode. Power assist is triggered when you pedal forward and stops when you stop pedaling (with a slight delay). You only need light pedaling force. Applying either brake automatically stops power assist, slowing the e-bike. Power assist turns off when the maximum speed for the selected power level is reached.

Use the gear shifter to set gears appropriately for road conditions. This requires less effort and results in faster, steadier travel.

I-ERS, Cruise Control and Ambient Light Detection (Only for ENGINE Pro)

• I-ERS (Intelligent Energy Recovery System): Recharges the battery on high speed or downhill (over 20km/h or 12mph at PAS 0/1).
• Cruise Control: Triggered by holding the thumb throttle for 8 seconds; released by braking, pedaling, or throttling.
• Ambient Light Detection: Headlight automatically turns on when it's dark.

Hand Throttle Control

In hand throttle mode, power assist is determined by twisting the throttle. Twisting it further increases motor power for acceleration. Release the throttle to slow down and apply brakes if necessary.

You do not need to pedal when using the hand throttle, but pedaling conserves battery charge and extends range.

Charging Your e-Bike Battery

Your e-bike uses a lithium-ion battery requiring a specific charger. Never use an unauthorized charger, as it can cause overheating, fire, or explosion. Contact your dealer for replacements if the charger is lost or damaged.

Charge the battery when the e-bike is not in use, with the battery turned OFF. You can charge it while mounted or removed from the e-bike.

[CAUTION]: Do not place the charger or battery near flammable substances, infants, or small children. Remove valuable objects from the vicinity during charging.

Charging time depends on the battery's state of charge. A fully discharged battery takes about 6 hours. The charger LED turns GREEN when charging is complete. Disconnect the charger then. Leaving it connected overnight is acceptable.

It is normal for the charger and battery to be slightly warm during charging.

Removing the Battery

The battery is an important and costly part, secured by a key to prevent theft. For added security, remove the battery when the e-bike is unattended. You may also need to remove it for charging at a location away from the bike.

To remove the battery:

1. Open the charging port cap and fold the bike.
2. Insert the key into the battery and hold it slightly while twisting clockwise to the end. (Note: The lock bar must withdraw completely to remove the battery).
3. Slip off the battery. The battery is heavy; handle with care to avoid dropping.

Maximizing the Riding Range

Several 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 speed changes consume more energy.
• Carrying more weight consumes more energy.
• Keeping tires properly inflated, the e-bike clean, and well-lubricated saves energy.
• Ensure wheels move freely when brakes are not applied; check brake adjustments frequently.
• Pedaling while riding consumes less electrical energy and increases range.

When the battery is off, the e-bike functions as a regular bicycle. For long, level, or downhill stretches, turning off the battery and pedaling conserves stored electrical energy.

Care and Maintenance for Your New e-Bike

General care involves keeping the e-bike dry, clean, and its moving parts well-lubricated, similar to a regular bicycle. Avoid parking in exposed areas.

Check brake effectiveness before each use.

For your e-Bike:

• The e-bike is designed for regular country road use for a single person. Extreme maneuvers (off-road, jumping, excessive load) can damage the e-bike and cause injury.
• Do not use high-pressure water streams for cleaning, as water can seep into the motor or wiring, causing rust or short circuits.
• Avoid parking outside in rain or snow. After riding in wet conditions, bring the e-bike inside and dry it thoroughly with a towel.
• Do not lose keys. If you lose one key, make a backup copy immediately. Losing both keys prevents battery removal.

Special Care for the Battery and the Charger

• Use only the supplied charger. Contact your dealer for replacements if lost or damaged.
• Do not open or alter the battery or charger.
• Keep the battery away from fire, corrosive substances, and water. Avoid high temperatures (e.g., direct sunlight for prolonged periods).
• Do not short-circuit the battery terminals.
• Battery charge holding capacity decreases with use. If it doesn't hold sufficient charge for short trips, contact your dealer for replacement. Under normal use, the battery lasts approximately 500 charge/discharge cycles.
• For extended periods of non-use, fully charge the battery and recharge it every 3 months. Store in a cool place.
• The battery is engineered for high capacity and long life. Do not use it to power other electrical devices, as improper use can damage the battery, shorten its life, and cause fire or explosion.
