| http://www.w3.org/ns/prov#value | - You do not need an assistant, and you do not need to hold the rear wheel up off the ground, thanks to the miracle of freewheeling. (Well, yes, unless the bicycle has a fixed gear or coaster brake.) The bicycle shown has a non-derailer drivetrain, and the chain was a bit slack, so I could keep the stick under the chain all the way around to the top.
