Proving it’s yours
Requests for documentation are most likely to come up when you sell in person. This especially applies to local peer-to-peer selling platforms like Facebook Marketplace. Bike shops might also want some proof of purchase. When you sell in person, it is on you to prove that your bike is yours to sell and not stolen.
- Proof of purchase: A document detailing proof of purchase is the easiest way to show that the bike you are selling belongs to you. This document can include the bike’s make and model, serial number, transaction information, and your details as the buyer.
- Bike registries: Use the serial number on the frame to add your bike to a bike registry. This will prove that your name is attached to it. It contains details about the bike, such as components, condition, and photos, and can even provide alerts if the bike is flagged as stolen.
Verifying condition
Anyone buying a used bike will be concerned with its condition. Bike shops and individual buyers will be hesitant to take a stranger at their word when it comes to how the bike was cared for in the past. Bringing along some proof that the bike has been in good hands can help you make the sale more easily.
- Service history: Did you take great care of your bike before selling it? Bring along proof of tune-ups, upgrades, or anything else you did to improve your bike. Showing that the bike is in great condition, proof of maintenance can increase resale value.
- Warranty information: There is a good chance that some of the components on your bike or even the bike itself are still under warranty. If that is the case, it can add value to your sale. Provide proof to make a seamless transaction.
