01 — Performance
Brushless AC Power
The cool-running brushless 4.0 HP AC motor with Grade H insulation starts as low as 0.3 mph and tops out at 12 mph — delivering smooth, consistent torque under the demands of continuous multi-user daily use without overheating. |
|
02 — Console
Built-In Convenience
A facility-grade console with everything users need — adjustable cooling fan, cell phone ledge, storage tray, tablet-friendly reading rack, water bottle holders, and USB charging port. Simple enough for first-timers, capable enough for regulars. |
|
03 — Display
Efficient Display
The bright white multi-window LED console displays 9 workout metrics simultaneously — speed, incline, distance, pace, calories, METs, pulse, watts, and time. Direct-access speed and incline buttons make every adjustment instant, keeping interval sessions seamless. |

04 — Heart Rate
Heart Rate Monitoring
Ergonomically positioned hand pulse sensors deliver instant contact-based readings, while the built-in wireless receiver pairs with standard chest straps (sold separately) for continuous, hands-free heart rate monitoring throughout every session. |

05 — Deck
Commercial-Grade Deck
A Habasit® 2-ply pre-lubed belt rated for 4,000 hours of use rides over a 1" reversible phenolic wax deck and 3" crowned rollers. Six cushioned elastomers distributed throughout the frame absorb impact on a 22" × 60" surface supporting users up to 450 lb. |
