Sure, you might want an indoor exercise, but don’t exactly have a ton of room. A folding bike is the perfect solution. With folded dimensions of just 16.75” x 18” and built-in wheels, you can completely store away the bike when not in use. While it is in use, though, you’ll get a stellar workout. There are eight levels of resistance and a monitor that displays your speed, distance, time, calories, and pulse that’s tracked through the handlebars. And you’ll want to keep pedaling for a while given that the seat is large and anatomically-designed, and the handlebars are padded.
