Used-bike inspection

If you’re buying this bike used

Before any test ride: both brakes should stop the bike firmly and release cleanly; both wheels should run true and be securely attached; tires should have no casing damage; and the headset, handlebar, stem, cranks and pedals should have no looseness or play.

Follow the full used-bike inspection order →
  • FrameLook closely for dents and hairline cracks around welds, the head tube and bottom-bracket area. Cosmetic scratches matter less than a change in shape or a crack line.Inspect the frame and fork →
  • BrakesMake sure both cables move freely and the calipers release cleanly. Check pad thickness, rotor wear and rotor alignment.Inspect the brakes →
  • E-bike systemConfirm the main battery charges with the correct charger, locks securely into its mount and has no case damage, swelling, corrosion or overheating marks. Power the bike on from cold, test every assist mode and ask for available battery-health and diagnostic records.Check the battery and electronics →
  • Wheels & tiresSpin both wheels and watch the rims for side-to-side or vertical movement. Check for dents, cracks, loose or uneven spokes and hub play, then inspect both tire casings for cuts, cracking or exposed threads.Check wheels and tires →
