Setup Guide

1. Assembly

Your Dynacraft Alpine Eagle bike comes partially assembled. Follow these steps to complete the assembly:

1. Handlebar Installation: Attach the handlebars to the stem. Ensure the brake levers and shifters are positioned comfortably and securely tightened.
2. Front Wheel Installation: Insert the front wheel into the fork dropouts. Ensure the quick-release skewer is properly tightened. Align the brake pads with the rim.
3. Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal threads counter-clockwise, and the right pedal threads clockwise. Apply a small amount of grease to the threads and tighten them securely.
4. Seat Post and Saddle: Insert the seat post into the frame. Adjust the saddle height to allow for a slight bend in your knee when the pedal is at its lowest point. Secure the quick-release lever.

2. Pre-Ride Checks

Before each ride, perform the following checks:

• Tires: Check tire pressure. Refer to the sidewall of the tire for recommended PSI.
• Brakes: Ensure both front and rear brakes engage firmly and stop the wheels effectively.
• Quick Releases: Verify all quick-release levers (wheels, seat post) are securely closed.
• Bolts and Nuts: Briefly check that all visible bolts and nuts are tight.

Operating Instructions

1. Shifting Gears

Your Alpine Eagle bike is equipped with an 18-speed derailleur system and grip shifters. The right shifter controls the rear derailleur (smaller gear changes), and the left shifter controls the front derailleur (larger gear changes).

• To shift to a higher gear (harder to pedal, faster speed), twist the shifter forward.
• To shift to a lower gear (easier to pedal, slower speed), twist the shifter backward.
• Always pedal lightly when shifting to ensure smooth transitions and prevent damage to the drivetrain.

2. Braking

The bike features front and rear V-brakes. The right brake lever controls the rear brake, and the left brake lever controls the front brake.

• Apply both brakes simultaneously for effective stopping.
• Avoid sudden, hard braking with only the front brake, especially at high speeds, as this can cause loss of control.
• Brake earlier and more gently in wet conditions, as braking performance may be reduced.

3. Riding Safety

• Always wear a helmet that meets safety standards.
• Obey all traffic laws and signals.
• Be aware of your surroundings and other road users.
• Use appropriate hand signals for turning and stopping.
• Avoid riding at night without proper lighting (front white light, rear red reflector/light).

Maintenance

Regular maintenance ensures the safety, performance, and longevity of your bicycle.

1. Tire Pressure

Check tire pressure before every ride. Maintain the PSI (pounds per square inch) recommended on the tire sidewall. Under-inflated tires can lead to flats and poor handling, while over-inflated tires can reduce traction and comfort.

2. Chain Lubrication

Lubricate your chain regularly, especially after riding in wet or dusty conditions. A well-lubricated chain reduces friction, extends component life, and ensures smooth shifting. Apply a small amount of bicycle-specific chain lubricant to each link while slowly pedaling backward, then wipe off excess.

3. Brake Checks

Periodically inspect brake pads for wear and ensure they are properly aligned with the rim. Check brake cables for fraying or corrosion. Adjust cable tension as needed to ensure responsive braking.

4. Cleaning

Clean your bike regularly with mild soap and water. Avoid high-pressure washers, which can force water into bearings. Dry the bike thoroughly after washing and re-lubricate the chain.
