Whether you’ve dreamed of running a marathon or making it a mile without stopping, purchasing a treadmill is a good first step toward achieving your goal.

However, treadmills often come with a large footprint, which isn’t feasible for small spaces.

Fortunately, several folding treadmills are on the market, so you don’t have to give up on your marathon dreams.

Folding treadmills work by allowing the running deck to be locked in an upright position, and they often come with wheels, making them easy to move and store.

To determine the best foldable treadmills, we considered the following factors:

  • Folding mechanisms. Some models fold more easily than others. We looked for products that are simple to use.
  • Special features. We considered treadmills that offer a variety of features, such as speakers, HD screens, cup holders, Bluetooth technology, and USB ports.
  • Warranties. Buying a treadmill is an investment, which is why we paid special attention to the warranties available for each product.
  • Price. We know that budgets can vary, so we included foldable treadmills at a variety of price points.
  • Customer reviews. The products on this list have mostly positive customer reviews.

Here are the 5 best foldable treadmills of 2021.
