    Follow road rules – Ride responsibly and remain aware of your surroundings.

    Aftercare for Your New Bike Initial Check-Up (First 50-100 miles)

    Gear Adjustment – New cables may stretch slightly; have a qualified mechanic check and adjust them.

    Brake & Wheel Check – Inspect brakes for wear and ensure wheels are aligned properly.

    Lubrication – Apply chain oil and check bolt tightness to maintain smooth performance.
