Performance and Workout Experience
The TR5500i excels in performance thanks to its 4.0 HP motor, offering consistent power for sprints, long-distance running, and interval training. The speed range up to 22 km/h makes it one of the fastest in its class, while the -2% to +13% incline/decline simulates real-world terrain variation.
The 8 compression shocks reduce joint impact and enhance workout comfort. Whether walking or performing HIIT routines, the treadmill remains stable and smooth.
Console and Technology
The 10” interactive touchscreen display is a major upgrade, offering vibrant visuals, easy program navigation, and compatibility with apps via Bluetooth and USB. Metrics tracked include pace, calories, distance, incline, heart rate, and more.
While it doesn’t offer native integration with streaming platforms (e.g., Netflix or iFit), it supports app syncing for fitness tracking. The Quick Set buttons make it easy to adjust speed and incline mid-run.
Build Quality and Durability
The TR5500i is built with a heavy-duty steel frame, supporting up to 159 kg (350 lbs)—ideal for heavier users or intense usage. The lifetime motor and frame warranty speaks to its long-term durability.
The belt is 2.2mm thick with a 1” deck, ensuring stability and long-term wear resistance. It’s a machine clearly made for frequent, high-intensity use.
Setup and Storage
Assembly is straightforward, though due to the unit’s weight (~120 kg), a second person is helpful. The EZfold™ system makes folding and unfolding relatively simple, aided by hydraulic assistance.
When folded, the treadmill takes up less floor space, although it’s still a large machine best suited for dedicated workout areas.

- Serious runners looking for commercial-grade performance

- Buyers on a tight budget
