Motorcycle Luggage - All-in-Ones

All-in-one rectangular bags that ride vertically on the rear of the bike provide storage space either in place of, or behind, the passenger. Since the bags are shaped like small suitcases, they’re easy to pack, and some come with backpack straps or even wheels for transporting them off the bike.
To use this kind of luggage on your cruiser, you’ll need a securely mounted backrest and a luggage rack. Typically, these bags come with a wide strap that slides over the backrest, and a pair of nylon-webbing straps that secure them to the rack.

Other considerations are pretty standard. Make sure your bags come with waterproof covers, and if you’re concerned about security when you leave the bike, at least buy a zipper lock and a cable lock to keep someone from opening the bag or walking off with it.

Recently, some companies have started bringing the rear-mounted bag concept to the rest of the motorcycling world with designs that let you install a supporting rack and bag on your sport bike or standard. These can be a great solution for bikes that don’t lend themselves to soft saddlebags, although they typically leave some brackets behind even when you’re not using the bag.
Other companies offer a different take on the all-in-one bag design, with strap-on luggage that combines a rear-seat bag with a couple of mini saddlebags.
