5. Operating Instructions
5.1 Adjusting Seat Height
The seat height is adjustable to accommodate riders between 5'4" and 6'2". Loosen the quick-release lever or bolt on the seat post, adjust the seat to a comfortable height where your feet can touch the ground while seated, and then securely tighten.

5.2 Shifting Gears
Your ZUKKA bike features a 7-speed shifter lever (RS25-7R) and a rear derailleur (RD-TY21). Use the shifter on the handlebar to change gears. Shift to a lower gear for easier pedaling on inclines and a higher gear for faster speeds on flat terrain. Always pedal lightly when shifting to ensure smooth transitions.
5.3 Braking
The bicycle is equipped with front and rear V-type brakes. Squeeze both brake levers simultaneously and gently to slow down or stop. Apply more pressure to the rear brake for controlled stopping and the front brake for stronger stopping power, but avoid sudden, hard front braking to prevent loss of control.

6. Maintenance
- Tire Pressure: Check tire pressure before each ride. Maintain pressure within the range indicated on the tire sidewall.
- Chain Lubrication: Lubricate the chain regularly, especially after riding in wet conditions, to ensure smooth operation and prevent rust.
- Brake Adjustment: Periodically check brake pad wear and cable tension. Adjust as needed to maintain effective braking.
- Bolt Tightness: Regularly inspect and tighten all bolts, especially on the handlebars, seat post, wheels, and crank arms.
- Cleaning: Clean your bike with mild soap and water. Avoid high-pressure washing directly on bearings and seals.
