Bike lovers know that nothing’s worse than getting a bike stolen. A close second is buying a stolen bike, even by accident, which can perpetuate bike theft and place you in a sticky situation. Verifying an electric bike’s authenticity, checking its serial number, and inquiring about ownership history can effectively avoid buying a stolen or damaged bike. Upway sources bikes directly from brands and sellers, including ownership history and inspection report. Every Upway e-Bike comes with a Project 529 registration kit included in the shipping box to defend against bike theft in the future.

Certified pre-owned e-Bikes are already verified

When you buy a refurbished electric bike from a trusted retailer, they’ve done the leg work for you and can confirm the bike is authentic, certified, and not stolen. These platforms source bikes directly from brands or bike shops so they know exactly where the models are coming from. They may also vet bikes bought from individual sellers. For example, Upway checks each incoming electric bike against the Project 529 bike registry to ensure stolen bikes are not sold on our website.

Ask seller about ownership and bike history

If you choose to buy a used e-Bike from a local listing, ask the seller about the history of the bike. Most sellers are genuine and simply selling their old e-Bike, but there are some shady deals out there to watch out for. Sellers may try to make a profit on a stolen bike or one with hidden damage. Bike purchases through private transactions don’t come with fresh warranties, and most existing warranties won’t transfer to a second owner.

Ask questions like:

  • Are you the original owner?
  • Do you have the original proof of purchase?
  • What is the total mileage?
  • Why are you selling the bike?
  • Are there any damaged, replaced, or upgraded parts?

It’s up to your discretion whether to close the deal based on the information you’ve gathered. But if the price is too good to be true, something’s fishy.

Enter the serial number into a bike registry

Due diligence would be entering in the bike’s serial number into a local or national bike registry that tracks stolen bikes. The serial number is typically located under or around the bottom bracket on the frame. Scratched out or covered serial numbers are a major red flag. This helps you avoid buying a stolen bike and can even help the original owner track down their property.
