4. Setup and Assembly
Follow these steps to assemble your Bezior X1500 e-bike:
- Unpacking: Carefully remove the bicycle and all components from the packaging. Retain packaging for future transport or storage.
- Handlebar Installation:
Loosen the stem clamp bolts. Insert the handlebar stem into the head tube, ensuring it is aligned with the front wheel. Tighten the bolts securely. Adjust the angle of the handlebars for comfort and tighten the handlebar clamp bolts.
- Pedal Installation:
Identify the Left (L) and Right (R) pedals. The left pedal has a reverse thread. Apply a small amount of grease to the threads. Screw the pedals into the crank arms by hand, then tighten firmly with a wrench. Note: Incorrect installation can damage threads.
- Front Wheel Installation (if separate):
Align the front wheel with the fork dropouts. Ensure the brake rotor (if disc brakes) is correctly seated in the caliper. Secure the wheel using the quick-release skewer or axle nuts, ensuring it is centered and tight.
- Seat Post and Saddle Adjustment:
Insert the seat post into the frame's seat tube. Adjust the saddle height so your leg has a slight bend at the knee when the pedal is at its lowest point. Secure the quick-release lever or seat post clamp firmly.
- Battery Installation and Initial Charge:
If the battery is separate, insert it into its compartment and lock it with the provided key. Before your first ride, fully charge the battery using the supplied charger. Connect the charger to the battery charging port, then plug it into a wall outlet. The indicator light on the charger will change when fully charged.

- Pre-Ride Inspection:
Before your first ride, double-check all bolts, quick releases, and connections. Test the brakes, gears, and ensure the tires are inflated to the recommended pressure (refer to tire sidewall for PSI). Familiarize yourself with the controls.
5. Operating Your Bezior X1500
5.1 Powering On/Off and Display
Locate the power button on the handlebar display. Press and hold to turn the system on or off. The display will show speed, battery level, pedal assist level (PAS), and trip distance. Consult the display's specific manual for detailed functions.
5.2 Pedal Assist System (PAS) and Throttle
- Pedal Assist: The X1500 features multiple levels of pedal assist. Use the '+' and '-' buttons on the control panel to adjust the assist level. Higher levels provide more motor assistance.
- Throttle: The throttle provides power on demand without pedaling. Use it cautiously, especially when starting.
5.3 Gear Shifting (M2000 27-Speed)
Your X1500 is equipped with a 27-speed M2000 gear system. Use the shifters on the handlebars to change gears. Shift to a lower gear for climbing hills and a higher gear for flat terrain or downhill riding. Shift smoothly and avoid shifting under heavy load.
5.4 Braking System
The e-bike features dual shock absorbers, indicating a robust braking system. Use both front and rear brakes simultaneously for effective stopping. Apply gentle pressure initially and increase as needed. Avoid sudden, hard braking, especially at high speeds or on loose surfaces.
5.5 Folding Mechanism
To fold your Bezior X1500:
- Ensure the bike is powered off.
- Lower the seat post completely.
- Open the frame folding latch, usually located near the center of the main frame. Follow the specific instructions for your model to release the safety catch.
- Fold the frame in half.
- Fold down the handlebars using the quick-release mechanism on the stem.
- Secure any folding clamps or straps to prevent accidental unfolding during transport.
To unfold, reverse the steps, ensuring all latches and quick releases are securely fastened before riding.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your e-bike.
- Cleaning: Clean the bike regularly with a damp cloth and mild soap. Avoid high-pressure washers directly on electrical components. Dry thoroughly.
- Battery Care:
- Charge the battery fully after each ride, or at least once a month if not in use.
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- Do not fully discharge the battery.
- Use only the original charger.
- Tire Pressure: Check tire pressure before each ride. The 26" x 4.0 fat tires typically require lower pressure than standard bike tires, but always refer to the PSI range printed on the tire sidewall.
- Brakes: Regularly inspect brake pads for wear and brake levers for proper tension. Adjust or replace as needed.
- Chain: Keep the chain clean and lubricated. Apply bicycle-specific chain lubricant regularly, especially after riding in wet conditions.
- Fasteners: Periodically check all bolts, nuts, and quick releases for tightness.
