What is the significance of GT BMX serial numbers and how can they be used to identify and authenticate a GT BMX bike?
GT BMX serial numbers are important because they serve as a unique identifier for each bike, allowing owners to track their bike's history and prove its authenticity. These serial numbers are typically located on the bottom bracket of the frame and can be used to verify the bike's model, year of production, and other details. By cross-referencing the serial number with GT's records or online databases, owners can authenticate their GT BMX bike and ensure its value and provenance.
