Buying a second hand bike can be a great way to save money, but it is important to make sure the bike is being sold legally. Stolen bikes are sometimes sold online, often at low prices and with limited information.
Before buying, there are several simple checks you can do to reduce the risk.
Ask for proof of ownership
A genuine seller should be able to explain where the bike came from and how long they have owned it. Ideally, they should have a receipt, order confirmation, service record or original paperwork.
Not every honest seller will still have the receipt, especially for an older bike, but they should still be able to answer basic questions confidently.
Check the frame number
Most bikes have a unique frame number stamped into the frame. It is often located underneath the bottom bracket, near the pedals, but it may also be found on the seat tube, head tube or rear dropout.
Ask the seller for the frame number before buying. If they refuse to provide it, this is a warning sign.

Look for signs of tampering
Check whether the frame number has been scratched off, painted over or damaged. A missing or altered frame number can be a major red flag.
Also look for unusual parts, mismatched components or signs that the bike has been quickly changed to make it harder to identify.
Be cautious with very low prices
If the price seems too good to be true, it may be worth questioning. High-end road bikes, electric bikes and mountain bikes should not usually be sold for a fraction of their value without a clear reason.
A seller who is rushing the sale, refusing questions or avoiding normal payment methods should be treated with caution.
Check the seller’s details
If buying through an online marketplace, look at the seller’s profile. A genuine seller is more likely to have a normal account history, clear photos and detailed descriptions.
Be careful with sellers who have multiple bikes for sale but cannot explain where they came from.
Meet safely
If meeting in person, choose a public place and do not carry large amounts of cash unnecessarily. A genuine seller should allow you to inspect the bike properly and should not pressure you into a quick decision.
Trust your instincts
If something feels wrong, walk away. There are plenty of legitimate second hand bikes available, and it is better to miss a bargain than risk buying a stolen bike.

Final thoughts
Checking whether a second hand bike may be stolen is an important part of buying used. Ask for proof of ownership, check the frame number, look for signs of tampering and be cautious with suspiciously low prices.
A genuine seller should be happy to answer questions and provide enough information for you to buy with confidence.
