• Inspect the frame in bright light, especially the head tube, bottom-bracket area, chainstays and clamped surfaces. Look for cracks, ripples, crushed sections or signs of impact.
• Stand behind and in front of the bicycle to look for obvious frame, fork or wheel misalignment. Ask directly about crashes, transport damage and repairs.

• Inspect the fork stanchions for scratches or coating wear, look for oil or dirt rings at the seals, and cycle the fork through its travel while checking for binding or bushing play.
• Ask for dated fork-service records. A clean exterior does not establish the condition of internal seals, oil or bushings.

• Identify the installed brake type and actuation before choosing replacement parts or service procedures. Inspect every installed pad and braking surface, then check the complete cable, hose or linkage path for damage, corrosion, leaks or binding.
• Before riding, test every installed brake separately at walking speed. Each should stop firmly and release cleanly without its control reaching the end of its usable travel.

• Apply the front brake and rock the bicycle to check the headset for play or notchiness. Inspect the handlebar, stem and clamp areas, then confirm every control is secure.
• Confirm the seatpost can be adjusted and that the saddle, pedals and their mounting hardware have no cracks, severe corrosion, looseness or damaged threads.

• Spin both wheels and watch for side-to-side or vertical movement. Check rim condition, spoke tension and each hub for roughness or play.
• Inspect both tire casings for cuts, cracking, plugs, bulges or exposed threads. Confirm the installed sizes are safe for the rims and available frame and fork clearance.
• Inspect both wheel-retention systems. Axles or quick releases should tighten correctly with undamaged threads, hardware and dropouts.

• Measure chain wear when applicable and inspect the chainring and rear sprockets for hooked, damaged or heavily worn teeth.
• Operate every available gear under light load. Hesitation, skipping or inconsistent engagement can reflect wear, damage, poor adjustment or mismatched parts.
• Turn the cranks slowly, feel for rough bearings and check for side-to-side play. Inspect the crank arms, chainring hardware and pedal threads for damage or looseness.

• Before riding, confirm both wheels are secure, tires are safe, both brakes function, and the headset, handlebar, stem, cranks and pedals have no looseness.
• Begin at low speed. Test steering, braking and shifting progressively, then load the drivetrain and suspension only after the basic safety checks pass.
• Listen and feel for repeated knocks, grinding, skipping, brake pulsation or movement at joints. Stop the test if the bicycle cannot be controlled safely.
