NordicTrack S 20i Treadmill

NordicTrack S 20i Review

Last Updated: February 13, 2021

If you’re looking for a budget home treadmill under £1000, the NordicTrack S 20i is worth considering. Being the first of three S-series treadmills available in the UK, it’s a fairly straightforward piece of equipment without most of the bells and whistles of modern-day running machines.

Here are some notable features of the S 20i:

  • 5-inch LCD Display

The S 20i features one of the simplest displays offered by NordicTrack. The modest 5-inch LCD screen is minimalistic yet functional, showing your workout stats right on the console. While it doesn’t come close to the full-color HD touchscreen in most other treadmills by the brand, they have been kind enough to leave space for your tablet by incorporating a tablet holder into the console. 

  • iFit Bluetooth Smart Enabled

iFit is a fitness app with over 16,000 workout videos, challenges, stat tracking, live personal training, and virtual running locations to offer. The S 20i treadmill itself doesn’t offer an iFit-enabled screen. However, you can enjoy the app over your own device, propping it up on the tablet holder and linking it to the treadmill via Bluetooth. 

You get free access to a single iFit profile for a year with the purchase of this treadmill. While most other NordicTrack machines come with free iFit family memberships as of 2021, even single-member access is appreciable for the price here.

  • 51 x 140 cm Tread Belt with Optional Cushioning

We love how NordicTrack always makes sure to offer a cushioning feature on all their equipment. This enables you to switch between a hard, road-like running surface and a shock-absorbing, cushioned surface that protects your knee and ankle joints. As for the belt dimensions, they’re good enough for running, although not as roomy as the commercial-grade machines.

  • 2.5 CHP Motor

The motor power on the S 20i is unremarkable, although it’s pretty quiet. We recommend against this treadmill if you’re on the heavier side and plan to run excessively for long periods. However, most individuals should be able to make it work for themselves as a casual home treadmill for brisk walks, jogging, and infrequent running.

  • 18 km/h Speed and 10% Incline Limit

NordicTrack treadmills are known for reaching speeds as high as 22 km/h. However, this one isn’t meant for high-speed runners. It still offers a top speed of 18 km/h, which should be enough for most people. You also have ten levels of incline to choose from, with the S 20i.

  • EKG Grip Heart Rate Monitoring

Heart rate sensors are incorporated into the handgrips of the S 20i. This helps you stay in the right heart rate zone as you work out and keep an eye on the console feedback.

  • Convenient Foldable Design

A useful attribute on a home treadmill is foldability, and the S 20i doesn’t disappoint. EasyLift™ Assist technology enables you to conveniently fold up the running deck after you’re done working out, freeing up valuable floor space.

  • Other Features

Other notable features include 1.9” precision-balanced rollers, dual 2” speakers, and a good warranty package.
