Don't think of it as a unicycle. Think of it as a miniature car. Ideal for situations where a bike is impractical and a traditional auto is a waste, the Ninebot One Self-Balancing Scooter is a fine option for urban transportation. Its electric motor offers a top speed of roughly 13 mph, and thanks to a sizable battery, it has a range of up to 18 miles. Its pedals fold up for storage, and with a built-in carrying handle and a weight under 20 pounds, it's easy to carry once you've reached your destination.
