Tired of walking, but can't quite cough up the scratch for a Segway? Say hi to the Inmotion R2 in the gallery below. It's a two-wheeled, personal electric vehicle that glides along at a leisurely 9MPH for around 18 miles. It's self-balancing -- you lean slightly forward or backward to move in each direction. Harder leans mean faster speed; tilt the removable handle left or right and you'll start doing donuts -- something Honda's similar contraption does hands-free. Even for this writer, who's never gotten on one of the contraptions before (nor anything even remotely similar), it took about four or five minutes to get the hang of it. After that? No real problems. If you get tired of riding, or perhaps there are too many people around to weave around, you can pull it behind you with the motor assisting -- you won't be dragging dead weight. Perhaps the most interesting aspect, though, is what it can do when connected to your smartphone via a companion app.
