When your workout is done, the Tread Flex easily folds upward toward the console, minimizing its footprint. The cylinder mechanism makes it easy to lift and gives a distinct, audible sound to let you know the deck is securely locked into the upright position. The physical lock pin helps ensure the deck stays upright. Additionally, the Tread Flex has locking caster wheels to allow your treadmill to be moved out of the way for stowing.

For unfolding, once the deck begins its descent, you can step back. The built-in cylinder takes over, lowering the deck smoothly and completely on its own. It’s built this way to ensure the deck is controlled as it lowers.

The Peloton Tread Flex is a folding treadmill that still offers a 0 to 12.5% grade incline, unlike other folding treadmills that might require manual adjustments or no incline at all. The incline knob allows you to change the grade in 0.5% increments. Additionally, the Peloton Tread Flex offers auto-incline that when enabled will automatically set your incline based on the Instructor’s cues throughout your class.

Generally, compact treadmills deliver excellent workout quality for walking, jogging, and moderate running; however, they often have smaller running surfaces and lower maximum speeds than full-size models. The Peloton Tread Flex does not compromise on speed with a 12.5 mph max speed and has the same belt size as our Peloton Tread Vision at 59” L x 20” W.

The total dimensions of the Peloton Tread Flex are 70.5” L x 33.6” W x 66.1” H. When folded, the dimensions are 37.8” L x 33.6” W x 66.1” H. It weighs 290 lbs.

We recommend a room with at least 24" of space to the left, right and front of the Tread Flex and 79" of clearance behind. The ceiling height minimum is 20" greater than the user’s height. However, additional space is recommended for bootcamp and other mat classes, such as strength, yoga, or Pilates.

Minor screen vibration is normal, particularly at higher speeds. If you notice excessive shaking, please ensure all bolts are tightened and the treadmill is level on an even surface.

The most important features to evaluate when buying a treadmill are belts, motor power, incline, and tech connectivity. Each of these directly impacts whether the machine will meet your fitness needs while fitting your lifestyle constraints. Specifically for folding treadmills, you’ll also want to consider the folding mechanism, which should provide support rather than requiring significant manual strength to fold or unfold the treadmill. Additionally, the folding treadmill should be stable and safely secured in place both when in use and stowed.

Many compact or folding treadmills support running at speeds up to 10 mph with belt lengths of 50 to 55 inches, which accommodates most recreational runners comfortably. The Tread Flex reaches speeds up to 12.5 mph and has a belt length of 59”.

A folding treadmill is a full-featured treadmill with handlebars, console, and running capabilities that folds for storage, while a walking pad is an ultra-slim, handlebar-free platform designed specifically for walking at low speeds. Walking pads typically support speeds up to 4 to 6 mph, slide under desks or furniture, and prioritize minimal footprint over workout intensity. Folding treadmills offer more versatility but require more storage space even when collapsed.

*Based on an internal 2025–2026 study of 2,069 new Tread runners who logged 3+ hardware treadmill workouts (excluding warm-ups/cool-downs) in both their first and sixth months of subscription. "Got faster" compares each runner’s best average workout speed in month 6 against month 1. Individual results vary. Results reflect observed outcomes for this analyzed cohort and may not reflect typical results.
