fitbill f.Walk Smart Under Desk Treadmill Review – Walk While You Work!

If you’re interested in establishing a regular fitness routine, one of the biggest challenges is actual-ly carving out enough time in your schedule to exercise. Long workdays take up most of your week, and sacrificing your free time to exercise can be a difficult option.

Rather than push fitness down in your list of priorities, you can incorporate it into your daily routine with an under-desk treadmill – just like the f.Walk from fitbill.

This smart machine is a mainstay on our list of the best treadmills for walking thanks to its sleek lie-flat design that packs in solid features without sacrificing performance. Let’s take a closer look at this treadmill’s components to see how it stacks up to the competition.


The f.Walk’s completely flat frame is by far its most eye-catching feature. Unlike more traditional treadmills – which offer built-in entertainment consoles to create a sort of ‘fitness station’ – the f.Walk is designed to integrate seamlessly into your workspace.

No matter what desk you have, the f.Walk can easily fit underneath it. The total footprint of the treadmill is just 24” wide by 59” long, while the tread belt sits just 5” off the ground for an easy step up and inconspicuous overall size.

The actual belt measures 18” wide by 47” long. This may not be as large as traditional running treadmills, yet it strikes a good balance between roominess and compactness. In any case, the vast majority of users should be able to stride fully on this model without any problems.

The f.Walk is also one of the lightest treadmills you’ll find anywhere – the full unit weighs just 64lbs, but can accommodate users weighing up to 220lbs.

Aside from the tread belt, the f.Walk manages to incorporate a statistics display into the body of the unit. It makes basic workout feedback, such as speed, time, distance and calories burned, ac-cessible at a glance.

Wheels are also built in, which – combined with the lightweight nature of the machine – allow you to pick up and move the treadmill without any hassle.

Of course, balance and safety are some common concerns with lie-flat treadmills like the f.Walk. Without any handrails, it may seem difficult or even dangerous to use the machine. However, while it may take a bit of getting used to, the f.Walk is generally stable and secure.

Placing it underneath your desk also gives you access to some external support should you need to slow down or step off the treadmill.

Core Features

The f.Walk utilizes a 1.0 CHP motor, which can deliver speeds between 0.5 and 3.7mph. This is a pretty standard speed range for a walking treadmill; while it doesn’t deliver anything fast enough for jogging or running, there’s plenty of power on tap for a wide range of different walking paces.

Generally, motors with greater horsepower tend to run more quietly than lower-powered motors. This is because the more horsepower available, the less the motor has to work to drive the rollers at a given speed.

The 1.0 CHP motor here is slightly more powerful than the 0.5 CHP motors you may find on many other budget walking treadmills. This translates into improved performance and less noise.

Secondary Features

In addition to the standard performance measurements, the f.Walk incorporates a few secondary features to elevate the total package.

One of the most helpful is the remote control included with the package. Because of the frameless design, there aren’t any physical buttons on the treadmill itself. The remote control allows you to adjust the speed of the machine without having to constantly bend over.

If you’d prefer not to use the remote, the f.Walk is also compatible with the fitbill app. This app allows you to control the treadmill from your smartphone as you walk without needing the sepa-rate remote.

The app also tracks your time spent walking, mileage covered and calories burned to help you monitor your progress over time.

On the mechanical side of things, the f.Walk utilizes an auto-oiling system that saves you from needing to manually lubricate the tread belt. Just add some oil into the designated compartment and the treadmill will take care of the rest.

While the warranty and setup information may not be traditional ‘features’, they’re still an im-portant part of the treadmill experience – and the f.Walk earns some bonus points on both fronts.

The treadmill ships completely assembled, which makes it easy to use as soon as you take it out of the box. The warranty is also generous; the main frame is covered for 10 years, while the motor is under warranty for two years and other parts are covered for one year.


Performance is the most critical aspect of any treadmill, especially when you’re buying a walking treadmill to use for multiple hours at a time. Thankfully, the f.Walk performs as advertised.

The 1.0 CHP motor runs smoothly and quietly, without any large jumps or skips. While it’s not com-pletely silent, the noise levels are consistently low enough to prevent distracting you while you work or watch TV on the treadmill.

The app connects to the treadmill via Bluetooth before you power it on, making it easy to adjust the speed while you walk without lag. The remote control includes similar buttons to turn the treadmill on and off and change the speed as you’re moving.

  • Lie-flat frame fits nearly anywhere
  • Smooth motor handles all walking paces
  • Remote control and app connectivity
  • Good warranty and no assembly required
  • Only offers walking speeds
  • Not perfectly silent when in operation
