The LifeSpan TR5500i is the Top Treadmill in the Series

The TR5500i replaced the 5000i model and became the top of the line model in LifeSpan's residential treadmill lineup.  With a wider running deck, more powerful motor and incline as well as decline capability, it's an attractive choice, especially given its competitive price tag.

The Buzz

The TR5500i was recently introduced as a replacement for the previous TR5000i model, with an all new updated look and enhanced features, making it much more attractive to buyers.

It's definitely the most feature-packed of the series, with just about everything you could ask for in a home treadmill.  You get a powerful 4.0 HP motor, a large 60" x 22" deck, incline and decline capability and over 40 workouts to choose from.

It appears as if it is competing head to head with NordicTrack's popular Commercial 1750, which is the only other sub-$2000 model to offer a decline option.

As such it is definitely a runner's treadmill, with solid construction and its generously sized, well cushioned belt.  There's plenty of room to stretch out your stride regardless of your size.

The TR5500i folds easily and can be transported to storage with the included wheels.  You can track your results with the USB port or options Bluetooth adapter, which allows you to sync via the LifeSpan Active Trac app to your favorite fitness applications.

As on some of the other models, including the TR4000i, you get the company's patented Intelli-Step step counter, Intelli-Key illuminated buttons and Intelli-Guard safety feature that pauses the belt automatically when you step off.

The TR5500i has the most workouts of any of the other treadmills in LifeSpan's line, including 4 heart rate programs, 2 customized, 34 presets and 6 decline training.  There's enough programming here to keep you motivated, with the ability to change things up so your workout is never boring.

The cushioning is high-grade and impact absorbing, the treadmill itself is very stable and secure with its anti-vibration technology.

All in all this one is a winner, and should be receiving more attention that it does given all of the great features and capabilities.

What We Say About the TR5500i

At around $1699 on sale, the LifeSpan TR5500i is great deal and is definitely giving the more popular brands like NordicTrack and Sole a run for their money.

With a strong, yet quiet motor, great cushioning, incline as well as decline, easy folding capability and over 40 built in workouts, it pretty much has everything you need.

The only thing missing is a touch screen, and it would be nice if the Bluetooth was included rather than being an option.  But for this price you really can't complain about much.  The LifeSpan TR5500i is definitely worth considering if you are looking for a solid home treadmill under $2000.
