This is commonly referred to as a "Goldie Bar" in respect to its inventor, Glen Goldie. Glen was, amongst other things, an inventor. An avid Harley enthusiast, he tried to make life easier for Hog riders! This device is an easy to use way of lifting one wheel off the ground to work on or clean a wheel, or work under the bike. It works by leverage. It is placed under the bike, in the center, roughly. Of course, only one wheel at a time. Easy to carry and store. Nothing to maintain, or break!
