Sure, the new Hummer H2 is cool — until you try to get it through baggage check. But, thanks to a partnership between GM and Montague USA, you can now purchase a Hummer that not only fits easily in the cargo hold, but lightens your wallet by less than $800 bucks. The catch? You’ve gotta pedal it. Witness the new Hummer Tactical Mountain Bike ($795), which in 30 seconds goes from trail to travel-ready by folding into a 3-foot x 3-foot x 1-foot pack. And lest you think that this Hummer isn’t rugged enough for hard use, consider this: It’s based on the model Montague supplies to U.S. Marines. (800) 736-5348 or www.hummer.com
