4. Setup and Assembly

Your PEXMOR mountain bike arrives approximately 85% pre-assembled. The following steps detail the completion of the assembly process.

4.1 Unfolding the Bicycle

1. Carefully remove the bicycle from its packaging.
2. Locate the folding hinge on the frame and release the safety latch.
3. Unfold the frame until it locks into place. Secure the safety latch.
4. Adjust the handlebar stem to the upright position and secure it.

4.2 Attaching Components

1. Handlebar Assembly: Insert the handlebar stem into the fork tube and tighten the bolt securely. Ensure the handlebars are straight and aligned with the front wheel.
2. Front Wheel Installation: Attach the front wheel to the front fork. Ensure the disc brake rotor is correctly seated within the caliper. Secure the quick-release lever.
3. Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Thread them carefully into the crank arms and tighten firmly with a wrench.
4. Seat/Cushion Adjustment: Insert the seat post into the frame's seat tube. Adjust the height to a comfortable riding position where your leg has a slight bend at the knee when the pedal is at its lowest point. Secure the quick-release clamp. The cushion height adjustment range is 80-97 cm.

5. Operating Instructions

5.1 Gear Shifting (21-Speed Shimano)

Your bike is equipped with a 21-speed Shimano gear system (3 front, 7 rear) for optimal performance across various terrains.

• Front Derailleur (Left Shifter): Controls the 3 chainrings on the front. Use for large changes in resistance (e.g., climbing steep hills or high-speed flats).
• Rear Derailleur (Right Shifter): Controls the 7 cogs on the rear cassette. Use for fine-tuning resistance and maintaining a comfortable pedaling cadence.
• Shift gears smoothly by pedaling lightly while shifting. Avoid shifting under heavy load.

5.2 Dual Disc Brakes

The mechanical disc brakes provide reliable stopping power in various conditions.

• The right brake lever controls the rear brake.
• The left brake lever controls the front brake.
• Apply both brakes simultaneously for effective and controlled stopping. Avoid sudden, hard application of the front brake, especially at high speeds, to prevent skidding.

5.3 Folding the Bicycle for Storage/Transport

The bike can be folded neatly in approximately 20 seconds for easy storage or transport.

1. Lower the seat post completely.
2. Release the handlebar stem quick-release and fold the handlebars down.
3. Open the main frame folding latch and carefully fold the bike in half.
4. Ensure all folding mechanisms are securely latched before moving the folded bike.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your PEXMOR mountain bike.

• Cleaning: Regularly clean the frame, chain, and gears with a mild detergent and water. Avoid high-pressure washing directly on bearings.
• Lubrication: Lubricate the chain regularly, especially after riding in wet conditions. Apply a suitable bicycle chain lubricant and wipe off excess.
• Tire Pressure: Check tire pressure before each ride. Maintain pressure within the range indicated on the tire sidewall. The tires are wear-resistant and anti-skid, designed for various surfaces.
• Brake Inspection: Periodically check brake pads for wear and ensure brake cables are not frayed. Adjust brake tension as needed to ensure responsive braking.
• Bolt & Nut Check: Regularly inspect all bolts and nuts, especially on the handlebars, seat post, wheels, and folding mechanism, to ensure they are tight.
• Suspension Care: Keep the shock-absorbing front fork and rear shock clean. Inspect for any leaks or damage.
