Troubleshooting
Bike won't turn on
This is a bicycle and does not have a power-on function. Ensure all components are securely attached.
Gears skipping or not shifting smoothly
Check derailleur adjustment. Ensure the chain is clean and lubricated. If the issue persists, consult a professional bike mechanic.
Brakes feel weak or spongy
Check brake fluid levels and ensure there are no leaks in the hydraulic lines. Air in the system may require bleeding. Professional adjustment is recommended.
Tires losing air quickly
Inspect tires and tubes for punctures. Ensure the tire bead is properly seated on the rim. Check the valve stem for leaks.
Unusual noises during riding
Identify the source of the noise. Check that all bolts and components are tightened correctly. Listen for creaks in the bottom bracket, headset, or pedals.

Care and Maintenance:
Cleaning: Regularly clean the frame with mild soap and water. Avoid high-pressure washers. Keep the drivetrain clean to ensure smooth shifting.

Brakes: Inspect brake pads for wear and ensure hydraulic lines are free from leaks. Have brakes adjusted by a professional if they feel spongy or ineffective.
Tires: Maintain proper tire pressure as indicated on the tire sidewall for optimal performance and to prevent flats.
Storage: Store the bike in a dry place, away from extreme temperatures and direct sunlight, to prevent corrosion and material degradation.
