Hi Bill,

I bought a nifty little frame jack that fits on the rail of the lift.

To remove the front wheel, you'd put the jack under the bike, jack it up a bit, then tie down the back of the bike, thus lifting the front wheel.

To remove the rear wheel, same deal, except you'd tie down the front of the bike.

The rear portion of the lift can also be removed easily, in the event you want to drop the rear wheel straight down.
