When reaching out to customer service for warranty assistance, it is best to have the bike's serial number on hand for fastest service. On a majority of our bikes, the location of this factory-applied decal is located on the rear stabilizer post, visible from the front of the bike. 

On our newest SC1, the serial number is formatted like A########## and is located on the inside of the front left leg (left from rider's perspective) near the bottom of the leg.

A photo of this decal is helpful in resolving any bike-related questions you may have, and the serial number beginning in 'A' followed by several numbers can be included in the sidebar of your ticket inquiry.
