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.
• When the instrument is in gears 1-5, it represents different speed levels, with gear 1 being the slowest and gear 5 being the fastest.
• Lower gears will make your battery last longer and make your ride safer.
• More power is needed to restore the original speed after emergency braking.
• Use the mechanical transmission to maintain the optimal pedaling frequency with the motor speed, making the riding experience more effortless.
• When shifting gears with the mechanical transmission, lightly step on the pedal to reduce wear on the transmission system.
• When riding in the rain, please maintain a low speed, which will provide greater friction for the tires.
• More weight will accelerate battery consumption.
• Do not start the bicycle by placing one foot on the pedal and crossing the other leg over the seat cushion, as this may cause the vehicle to suddenly accelerate. The correct way to start is to sit on the seat, hold the handlebars with both hands, and then start the vehicle.

3.2 Pre-ride Preparation

Regardless of your level of experience, you should carefully read the "User Manual" and perform a safety check on the vehicle. In addition, please make sure you are familiar with the following vehicle-related information.

Before riding, please check the following information about the vehicle:

• Whether key parts such as the front wheel, rear wheel, saddle, and handlebars are loose. If they are loose, they must be tightened before riding.
• Whether the brakes and handles are functioning properly.
• Whether the tire pressure is normal.
• Whether the battery is fully charged.
• When riding at night, check if the front and rear lights of the vehicle are working properly.
• Whether the display components of the instrument are displaying correctly.
• Please wear a cycling helmet and protective gear in accordance with local laws and regulations.
