What's the cheapest way? Find the cheapest stands, I guess. Perhaps a floor jack and a ratcheting tie down rig of some sort would work but I'm really not a fan of going ghetto when I work on my bikes. Maybe Harbor Freight has something out there. The rear stand is something you could certainly use more than twice a year for things like chain adjustments and cleaning. We all would like to spend less money but sometimes there isn't much choice. My friend made a rear stand out of wood way back when. It worked but wasn't very confidence inspiring.
