Register your bike and if it is stolen and recovered by police, it could be traced back to you. We suggest you register on 529 Garage, providing free services for storing your e-bike information so that police and e-bike shops could easily search it. You can also register your e-bike information with some of your related local agencies.
For registering your e-bike, we recommend you note your e-bike serials and order information. The Heybike e-bikes serials could be found at the headtube.
On the other hand, insuring your e-bike can also greatly reduce losses from theft. For more details about insurance, you can refer to Bicycle Insurance.
