Tern frame numbers

For warranties, insurance claims, or reporting a stolen eBike, the frame number plays a huge role in verifying the vehicle is attached to the owner. Depending on where the manufacturer decides to print the frame number, sometimes they can be hard to find, so we’re here to help! In this episode, we will go over Tern eBikes.

Tern bikes carry two numbers. The frame number is engraved into the frame and is the one you use for insurance and police reports. The Service Tag is an 8 character code starting with a “T”, printed under a QR-code sticker, and Tern uses it for registration and warranty service. Write both down.
