Check the fit before the condition
Ask for the model, size and year before viewing. Compare those details with the maker’s size chart. Test whether you can reach the brakes, put a foot down and steer comfortably. Leave enough time to compare another bike if you are between sizes.
Verify ownership
Ask for the serial number and proof of purchase where available. Check whether the serial is readable and search any relevant stolen-bike register. Walk away if the seller cannot explain why identifying marks have been removed or if the ownership story changes.
Inspect it in daylight
Look for cracks, dents or damage around frame joints, the fork and the area near the pedals. Spin the wheels and watch for wobble or rubbing. Squeeze both brakes and try shifting through the gears on a short, low-speed ride if the bike appears safe. Ask a bike shop to inspect it if damage or play is unclear.
Compare the full cost
Add likely tyres, drivetrain, brakes or servicing to the asking price. For a used e-bike, ask about battery condition, original charger and access to diagnostics. Compare the total with a serviced used bike or a new bike that includes warranty support.
