Quick answerAn upright exercise bike puts you in a more upright position on a wider seat than a spin bike, which suits steady rides and casual use. A folding upright bike, often called an X-bike, trades some size and adjustment for easier storage. Check the inseam range against your own, the maximum user weight, the resistance type and levels, and the footprint. For example, Sunny Health & Fitness lists its 16-level upright bike for inseams of 25.6 to 37.4 inches and users up to 300 lb, and its folding X-Bike for inseams of 28.3 to 33.5 inches.

Which exercise bike is right for you?

Exercise bikes come in several styles. This guide covers upright and folding upright bikes. If you want a race-style riding position, see our spin bike guide; if you want back support and an easier step-on, see our recumbent bike guide; and for fan resistance with moving handles, see our air bike guide.

Any of these counts toward activity goals. The Physical Activity Guidelines for Americans say adults need at least 150 to 300 minutes of moderate-intensity aerobic activity each week, and that any amount of physical activity has some health benefits. Choose the bike you will actually ride.

Specs that matter

Folding bikes: what you give up

Folding upright bikes save space. Sunny lists its X-Bike at 33.5 inches long in use and 22.4 inches long when folded, with transport wheels.

The trade-off shows in the specs. The folding model's inseam range is narrower, at 28.3 to 33.5 inches versus 25.6 to 37.4 inches on the upright, and its seat moves up and down only. Very tall or short riders should check fit carefully before choosing a folding bike.

Warranty can differ too. Sunny lists a 3 year structural frame warranty and 180 days on other parts for the X-Bike, so read the warranty terms for any bike you compare.

Recalls and safety

Exercise bike parts can fail. In 2023 the U.S. Consumer Product Safety Commission announced a recall of about 2.2 million Peloton Bikes, model PL01, because the seat post assembly could break during use. Peloton received 35 reports of the seat post breaking and detaching, including 13 reports of injuries such as a fractured wrist.
