Motorized suitcase saves your back

One of the challenges of traveling the world while continuing to work is that laptops, projectors, extra batteries and other gear can be heavy. And pulling a suitcase can be bad for your back. Finally, a well designed -- albeit expensive -- suitcase comes to the rescue.

On my recent two-month trip through Greece, one of the challenges I faced was getting all my stuff from one place to the next. After all, I was carrying all my clothes, all my gear, including two laptops, extra batteries and other heavy stuff and a whole bunch of things acquired along the way: Books, gifts for loved ones back home, you name it. My luggage had roughly doubled in weight from when I had left home.

It's not just the weight. I've found that the twisting motion involved in pulling a wheeled suitcase can be very bad for your back. The potential for injury is compounded by uneven sidewalks. I destroyed the handle on my brand-new suitcase -and nearly wrecked my back, too -- pulling it through the cobblestone streets of Mykonos in search of a room.

Now, however, a small UK company called Live Luggage plans to start selling Thursday what it calls a power-assisted (PA) case. That's right, a motorized suitcase.

The suitcase uses several innovations that make 65 pounds of stuff handle like it weighs only 6.5 pounds. The first is, of course, its motors -- one in each wheel. It doesn't start rolling by itself, but uses "force sensors" to figure out when you're pulling it, then gives you help with the forward motion.

The second innovation is what the company calls an adjustable anti-gravity handle. This is a simple brace that leans the top of the suitcase back over the wheels, instead of forcing you to hold the top of the case up with your arm. The company says the handle design places 85 percent of the weight onto the wheels. Every suitcase should have this.

Third, the suitcase has relatively large "pan-cake" wheels, placed far forward. The wheels are solid and capable of supporting large loads. A flexible rim enables the suitcase to be pulled without damage over uneven surfaces (like the narrow streets of Mykonos).
