Don't skimp out and get something cheap. Spend a bit (lot) more and get a really good lift. My only regret is I didn't buy one 20 years earlier!
I use it for so much more than just the bikes. It's big enough to put a lawn tractor or snowmobile on. So much nicer than working on a cold cement floor.
It's just a great adjustable work surface. Awesome for wood working projects, painting, and much more.
I've even thrown a table cloth over it and used it as a buffet table!
My Titan is 52" wide with extensions, and lifts 42" high.
