Intenza builds the heaviest treadmill on the boutique commercial market — and that is the entire point. Most design-led cardio brands chase a silhouette and quietly surrender stability to get it. Intenza went the other direction: build a deck heavy enough and a frame rigid enough that the machine feels like solid ground underfoot, then make it beautiful.

ConnectFit specifies Intenza treadmills for clients who want a cardio floor that looks like a design hotel or a boutique studio without giving up the durability a real commercial facility demands. Rated through 4,000+ hours of testing, quiet under load, and stable at full pace.

Why We Specify It

• Heaviest-in-class stability. At 635 lbs shipping weight, this is not a raised-platform treadmill that bounces and drums at speed. The mass does the work.
• 4 HP industrial-grade AC motor. Continuous-duty AC, not an inflated peak-horsepower DC rating dressed up for a spec sheet.
• Low 10.6" step-up height. Genuinely important in multifamily, hospitality, and 55+ settings where ceiling height and user confidence both matter.
• 22" × 61" running surface. Full running belt, not a walking deck sold as a runner.
• Speed range to 15.6 mph. Handles real interval training, not just steady-state cardio.

Three Configurations

• 450Ti2S (110V) — the standard-outlet build. Specify this when you cannot get dedicated 20-amp service to the machine location, which is most residential and many light-commercial retrofits.
• 450Ti2 — the full commercial build on dedicated power. The volume choice for property-management and hospitality fitness rooms.
• 550Te2+ — the flagship. Heaviest frame, best console, specified for boutique studios and Class A amenity floors where the equipment is part of the design brief.
