ProForm City L6 Review

Quick Summary

The ProForm City L6 comes into the family of home fitness machine as a high-quality introductory model, built to fold and store away with ease. At only $799, it lacks the bells and whistles of a higher-priced unit, but should be an excellent buy for the right person.

As an entry-level treadmill, it prefaces the ProForm Carbon and Pro Series, which both feature integrated screens, larger motors, and bigger tread space, for prices ranging from $999 to $1,999. That said, the new City series, led by the L6, is built to satisfy speed-walkers and slow joggers in a very small space with little fuss.

The treadmill comes iFit-enabled, which allows users to keep their workouts exciting through virtual runs across the globe from the comfort of their home. Customers receive one-year free on the Family Membership, valued at $486, with the $799. A good price point, the foldable storage option, and a solid warranty, make this machine a strong choice. An attractive design is also part of the package when considering this machine.

The ProForm line-up of treadmills is a consistent winner among the rankings, year after year, which is why the City L6 enters the arena with great expectations. Clearly an entry-level unit designed to fit in a small spaces and easily fold away, it does feature a sturdy build, iFit programming, and Bluetooth technology. Add in a solid warranty plan and one finds all the ingredients for a popular model.

The ProForm City L6, like other models in the family, includes the iFit program with Google Street View which provides users with a huge range of exercise options every day. Live trainers will even help trainees about the location they are running through during the workout, all the while able to control the machine whilst doing so. iFit does require a monthly subscription to unlock its full features, but purchasers of the City L6 receive one-year free on the Family Membership plan. For those who want to discontinue the program after this due to the $486 annual cost, the machine still operates independently of it and does have an integrated tablet holder and Bluetooth technology for whatever program they’d like. 

One point of note that customers will recognize upon sight, this is a smaller treadmill best for fast walking or slow jogging. It doesn’t have incline or decline options and the speed goes up to 8 miles per hour. That said, a lot can be done in small spaces with the right treadmill, and customers do get a 10-year warranty on the frame with one-year for parts and labor.

As one would expect from a smaller, space-saver model, the belt is shorter and more narrow than most of its larger peers. Measuring 17.5 by 45 inches, the treadmill operates on 1.6-inch precision rollers and utilizes ProShox Cushioning to minimize impact. At only 29 inches wide and 70.25 inches deep, the machine only stands 44.5 inches high when unfolded and in use. Easily foldable and weighing 125 pounds, it’s designed for users who value time and space. That said, the unit can bear up to 250 pounds in weight, which is less than larger models, but keep in mind it is a signifcantly smaller machine.

This treadmill is entry-level in its series, yet powerful enough for speed-walkers, joggers, and shared use. Performance specs include a high quality 1.6 CHP Mach Z.  

Workout Programs

Like the rest of its company line-up, the ProForm City L6 comes iFit-ready which allows for nearly unlimited workout routines as well as live, dynamic training from remote professionals who can control the machine. Unlike more expensive models, this unit does not contain pre-programmed routines, nor does it include an HD screen or tablet. Users can bring their own phone or tablet, or use their home television. Meanwhile, a data display is afforded on the console which marks time and allows users to control speed. 

The iFit workouts can be quite exciting since they let users virtually tour the world. Experience a new destination every time you train, or repeat a favorite, and try to outperform your old stats. You can train solo along Google Maps routes or work with celebrity coaches like Jillian Michaels. The purchase comes with a one-year membership to the program, but the machine can be operated without that if users would ever want to discontinue the service. 


The workout surface is compact at 17.5-inch x 45-inch, so there’s room for walking but not fast, full strides. Maximum speed is 8 mph, and there is no incline range offered. Commercial-grade ProShox Cushioning facilitates much less impact to your joints compared with an outdoor track. This feature helps users train for longer, and also protects the tread belt.

The L6 also includes folding technology which allows users to easily move and store it as desired. The physical features of this treadmill include a small display on the console which shows time elapsed and allows for speed control. Bluetooth compatible, users can either use their own tablet or phone, or home television.

Warranty & Guarantee

The Commercial Series treadmill warranty includes:

– Frame: 10 years

– Parts/Labor: 1 year

Additionally the manufacturer provides a 30-day money back guarantee.


The ProForm City L6 is a reliable, high-quality treadmill that will satisfy the right user. While this machine is not designed for advanced runners desirous of long strides, it does cater to the jogger or walker who values space. Users can either bring a tablet or user their own television set, or perhaps just use the machine. There’s no question this treadmill will help users tone, tighten, and burn calories

It’s an ideal machine for a busy professional, whether in the home or office, or perhaps a beginner who simply wants to walk fast and far. Definitely not for people wanting all the bells and whistles, it’s definitely the perfect machine for the right person.
