Cruisers will rejoice in a tiny electric bike—it folds to fit in a backpack and even the smallest of lockers—that easily goes from the boat to the dinghy to the street. Powered by lithium-ion batteries in the front, waterproof 10-inch wheel, the bike has a range of 10 miles (at 15 mph) between charges. A lightweight aluminum frame brings it in at a manageable 24 pounds. Jupiter Bike 2.0, $895, www.jupiterbike.com
