The app also offers workouts, which auto-adjust the speed to your pace via sensors under the belt. It felt awkward, since I couldn’t figure out how to slow the pace without the device totally stopping. You switch between modes within the app or on the display, and you can stop and start the machine using the app or remote. I like to use the machine in manual mode, and I tend to use the app more than the remote, because the remote connectivity is inconsistent.

The machine feels like it will have a long lifespan. Its heft makes it harder to move around than the Sperax, and while the folding capability is a win in general, if you plan to slide this under something, make sure the folded height (5.4 inches) will work. Here’s my full review. —Kristin Canning

WIRED

• Doubles as a treadmill with an adjustable handrail
• Impressive speed and incline ranges
• User-friendly companion app that syncs to unit

TIRED

• Speed may not be fast enough for users who want to run
• Workout data was occassionally wonky on the app

The Urevo Strol 2S Pro doubles as a treadmill and feels shockingly stable underfoot for how relatively lightweight it feels. I’ve tested several affordable treadmills, and they tend to feel wobbly at higher speeds, but this one remained firmly in place even as I ran on it at top speed and incline (7.6 mph and 9 percent). That top speed isn’t fast enough if you’re looking to really sprint, but it’s definitely ample for a good workout.

If you want to use the treadmill as a walking pad, you can keep the handrail down, which limits the top speed to 4 mph (though you can still use the full incline functionality). There’s a display on the front of the machine that cycles between time, distance, calories, incline, and speed. To access faster speeds, you have to put the handrail up, which requires you to use a hex tool to tighten it into place. The handlebar has a display as well, and you can control the machine’s basic functions from there. There’s also a tablet holder you can attach.
