4. Operating Instructions
4.1 Shifting Gears
Your ZUKKA Beach Cruiser Bike is equipped with a 7-speed Shimano shifting system (RS25-7R shifter and RD-TY21 derailleur).
- To shift to a higher gear (for faster riding or downhill), twist the grip shifter towards you (higher number).
- To shift to a lower gear (for easier pedaling or uphill), twist the grip shifter away from you (lower number).
- Shift gears while pedaling lightly to ensure smooth transitions. Avoid shifting while stationary or under heavy load.

4.2 Braking
The bike features dual V-brakes for reliable stopping power.
- The right brake lever controls the rear brake.
- The left brake lever controls the front brake.
- Apply both brakes simultaneously for controlled stopping. Avoid sudden, hard application of the front brake, especially at high speeds, to prevent loss of control.

Regular maintenance ensures the longevity and safe operation of your ZUKKA Beach Cruiser Bike.
5.1 Pre-Ride Check

- Bolts & Quick Releases: Verify all bolts, nuts, and quick releases are tight.
5.2 Cleaning and Lubrication
- Clean the bike regularly with mild soap and water, then rinse and dry thoroughly.
- Lubricate the chain every few rides or after riding in wet conditions. Use bicycle-specific chain lubricant.

5.3 Professional Servicing
It is recommended to have your bike inspected by a professional bicycle mechanic at least once a year, or more frequently if you ride often or in challenging conditions.
6. Troubleshooting
This section addresses common issues you might encounter. For complex repairs, consult a professional bicycle mechanic.
- Brakes feel weak: Check brake pad alignment and wear. Ensure brake cables are properly tensioned.

- Tire is flat: Locate the puncture and repair or replace the inner tube. Ensure the tire is properly seated on the rim before re-inflating.
