3. Pre-ride Instructions

3.1 Riding Techniques

• When the vehicle instrument is in gear 0, the motor is in a no-output state, and the vehicle can be ridden like a normal bicycle.
• In gears 1-5, different speed levels are represented, with gear 1 being the slowest and gear 5 being the fastest.
• Lower gears conserve battery and improve ride safety.
• More power is needed to restore original speed after emergency braking.
• Use the mechanical transmission to maintain optimal pedaling frequency with motor speed for a more effortless experience.
• When shifting gears, lightly step on the pedal to reduce wear on the transmission system.
• When riding in the rain, maintain a low speed for better tire friction.
• Increased weight accelerates battery consumption.
• Do not start by placing one foot on the pedal and swinging over the seat. The correct way is to sit on the seat, hold the handlebars, and then start the vehicle.

3.2 Pre-ride Preparation

Regardless of experience level, carefully read this "User Manual" and perform a safety check. Familiarize yourself with the vehicle:

• Check if key parts (front wheel, rear wheel, saddle, handlebars) are loose. Tighten if necessary.
• Ensure brakes and handles are functioning properly.
• Verify tire pressure is normal.
• Confirm the battery is fully charged.
• When riding at night, check if front and rear lights are working.
• Ensure display components on the instrument are functioning correctly.
• Wear a cycling helmet and protective gear according to local laws and regulations.

5.1 Battery Technical Data and Precautions

For transportation safety, the battery is guaranteed to have 30-40% charge when it leaves the factory. This charge will decrease with transportation time. Please charge the battery upon receipt.

Your bicycle is powered by a lithium-ion (Li-Ion) battery. Follow these instructions:

• The battery is for this vehicle only. Do not connect it to other electronic devices.
• Do not modify, open, or disassemble the battery pack, as this may cause short circuits, fires, or malfunctions.
• Handle the battery with care to avoid dropping it.
• Keep sharp or metal objects away from battery electrodes and charging ports to prevent short circuits and fires.
• Do not expose the battery to excessive heat or high temperatures.
• Do not immerse the battery in water.
• Before maintenance, cleaning, or repairs, turn off the power and unplug the charger or battery plug.

5.2 Battery Usage Instructions

Before assembling the battery, ensure the electrode area is free of foreign objects to prevent short circuits and damage.
