Remove the battery

Visual depiction of battery removal:

• Step 1: Open the battery compartment and fold the bike.
• Step 2: Insert the key into the battery lock and turn clockwise until the lock bar retracts.
• Step 3: Carefully slide out the battery.

Check that the Package is Complete and Undamaged

Your e-bike carton should contain:

• The main body of the e-bike (frame, front and rear wheel, gear, chain, brakes, battery, rear fender).
• The handlebar subassembly with battery keys, connected to the main body via brake cables and electrical wires. It includes brake levers, gear control, throttle, and a display panel.
• The seat, attached to its pedestal stem.
• Tools, one charger, and a pair of foot pedals in a separate box.

Tire Pressure: Before riding, check tire pressure. Recommended pressure for 20"x4.0" tires is 30 PSI.

Assembly - Step 1: Attach the handlebar subassembly

Stand the e-bike on its kickstand. Lock the steering column, insert the handlebar stem, ensure the fork points forward, and orient the handlebar. Tighten using the quick lock.

Assembly - Step 2: Installing the Seat and Pedals

Insert the seat pedestal into the seat column and tighten the built-in lever. Attach the left and right pedals to the crank arms, noting the distinction, and tighten with multi-tools.

Assembly - Step 3: Charging the Battery

Inflate tires to proper pressure. Your e-bike is now a functional bicycle. Check all tightening points. Adjust handlebar height and seat position for comfort.

Connect the charger to a wall outlet and the battery's charging terminal. The charger's LED is RED during charging and GREEN when complete. Turn the battery OFF during charging. Disconnect the charger when done and replace the rubber cap. When the battery is installed and ON, the display panel shows the charge level.

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

Operating Your New e-Bike

Turning the Bike On

1. Twist the battery lock counterclockwise 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 or pedal. Adjust power level using control buttons (Level 1 is slowest, Level 5 is fastest, Level 0 is human mode).

Your e-bike is powered by a rear-hub motor, controlled by the battery. You can choose between pedal-assist-only mode or full power mode (check local laws for permissibility). A hand throttle is also available.

Your First Ride

(Reprinted from Safety and Compliance section) Be very careful during your first ride. E-bikes accelerate faster than regular bicycles. Practice in an open area. Avoid sudden hard pedaling. With practice, you will enjoy the pedal-assist function.

Pedal-Assisted

To use pedal-assist mode, the battery must be on. Pedal assist is triggered when you pedal forward and stops when you stop pedaling (with a slight delay). Apply light, continuous force to the pedals. Applying brakes will automatically stop power assist. Power assist will also turn off when the maximum speed for the selected level is reached.

Use the gear shifter to select appropriate gears for road conditions and pedaling. This will require less effort and result in faster, steadier travel.

Cruise Control

Cruise control is activated by holding the thumb throttle for 8 seconds. It can be released by braking, pedaling, or throttling.

Thumb Throttle Control

In hand throttle mode, power assist is determined by twisting the throttle with your left hand. The further the throttle is twisted, the more power is delivered. To slow down, release the throttle and apply brakes if necessary. You do not need to pedal when using the hand throttle, but pedaling can conserve battery energy.

Charging Your e-Bike Battery

Your e-bike uses a lithium-ion battery and requires a specific charger. Never use a substitute charger, as this can cause overheating, fire, or explosion. Ensure the charger voltage matches the battery voltage. Contact your dealer for a replacement 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 the battery while it is mounted or removed from the e-bike. Do not place the charger or battery near flammable substances, infants, or small children. Avoid prolonged exposure to high temperatures. Do not short-circuit the battery terminals.

To maintain battery life, avoid charging until completely discharged. It is recommended to charge when the battery level is below 20%. If storing for extended periods, charge fully and recharge monthly. If not used for several months, the battery may self-discharge and become unchargeable.

A completely discharged battery takes approximately 6 hours to fully recharge. The charger's LED changes from RED to GREEN when charging is complete. Disconnect the charger promptly.

It is normal for the charger and battery to be slightly warm during charging. Leaving the charger connected overnight is acceptable.

Removing the Battery from the e-Bike

The battery is locked in place with a key for theft prevention. For added security, remove the battery when the e-bike is unattended. You may also need to remove it for charging elsewhere.

To remove the battery:

1. Open the charging port cap and fold the bike.
2. Insert the key into the battery, press and hold the key, then twist clockwise until the lock bar fully retracts.
3. Carefully slide off the battery, as it is heavy.

Maximizing the Riding Range

Several factors affect electrical energy consumption and riding range:

• Fully charge the battery before long journeys.
• Rough roads and hilly terrain consume more energy.
• Frequent speed changes consume more energy.
• Carrying extra weight consumes more energy.
• Keeping tires properly inflated and the e-bike clean and lubricated saves energy.
• Ensure wheels move freely without brake drag; check brake adjustments regularly.
• Pedaling while riding conserves electrical energy and increases range.
• When the battery is off, the e-bike functions as a regular bicycle. Consider turning off the battery on level or downhill stretches during long journeys to conserve energy.
