For a 24/7 franchise or boutique studio that wants its cardio floor to give power back, the SportsArt G660 is a non-motorised slat-belt treadmill: the runner drives the belt, and the ECO-POWR integrated inverter feeds the energy they generate back into your building's circuit through a standard power socket, at up to 200 W maximum output.
It suits operators running continuous multi-user sessions who want sprint-style and sled-push conditioning, with a curved slat deck running 3.0 to 20.0 km/h at a fixed 7% (4°) incline, a 45 to 150 kg user range, and a lifetime frame warranty backing the commercial build.
What sells me on the G660 is the slat belt paired with the ECO-POWR inverter: the runner drives the belt, and the energy they generate goes back into your building's circuit, up to 200 W at peak, with Human Watts and Instant Watt to Grid on the console.
The incline is fixed at 7%, so it isn't built for variable gradient work. For fit-outs, units can be daisy-chained, and the manual allows up to 9 on a 230 V, 10 A circuit, which keeps cabling tidy.

Every session on this treadmill feeds usable electricity back into your building. The ECO-POWR™ integrated inverter captures the energy a runner produces and returns it to your facility's circuit through the power cord.
SportsArt rates the inverter at 20 W input and a maximum output of 200 W, and the console shows the live figure as Instant Watt to Grid.
What this means for you: In a busy facility, the running that is already happening becomes a source of electricity instead of a drain on it.
ECO-POWR™ is SportsArt's patented micro-inverter technology. A generator captures the runner's movement and the inverter turns it into utility-grade electricity that can flow straight back into your wiring for immediate use.
What this means for you: This is the engineering that separates a sustainability claim from a measurable return of electricity to your facility.
The energy a member spends running does not disappear into a brake. Here it is captured and returned to your building as usable power.
For operators tracking carbon and energy targets, this gives you a line item you can actually report on.
What this means for you: Members can watch their own contribution climb on the console, which turns sustainability into something they can see and feel.
There is no drive motor here. The belt moves only as fast as the runner drives it, so the machine responds instantly to effort.
That also removes the single most failure-prone and power-hungry component on a traditional treadmill.
What this means for you: For a high-throughput floor, fewer powered components means fewer things that can fail between services.
The runner sets the pace with their stride, from a steady warm-up to a full sprint. Because there is no motor ramping up and down, pace changes happen the instant the runner changes effort.
What this means for you: Interval work feels natural because the belt speeds up and slows down exactly as fast as the runner does.
The running surface uses individual slats rather than a single continuous belt. Slat construction is built to take repeated high-impact footstrike across a commercial day.
At 147.3 cm long and 48.3 cm wide, it gives runners room for a full stride at speed.
What this means for you: Slat belts are the surface serious runners expect, and they stand up to the hours a commercial floor demands.
The frame is commercial-grade with reinforced construction, built to carry a 214 kg unit through continuous multi-user duty. It is rated for users from 45 to 150 kg.
A frame this heavy sits planted and stable even during flat-out sprint efforts.
What this means for you: The lifetime frame warranty tells you the brand expects this chassis to outlast the fit-out around it.
Two built-in modes cover two different jobs: Run for self-paced running and interval work, PUSH for sled-style resistance driving.
That lets one piece of equipment serve both cardio and conditioning sessions on the same floor.
What this means for you: A studio or functional floor gets running and pushing work from a single footprint instead of two machines.
The console displays a full set of readouts so coaches can program to a specific metric, not just a time on the clock. Pace, METS, Human Watts and Cal/Hr are all there at a glance.
What this means for you: Trainers can build sessions around power output or METS, which gives group and PT programming real structure.
Instead of wasting the runner's braking energy as heat, the ECO-POWR™ system captures it and sends it back to the grid. The resistance the runner feels is the same system that generates your electricity.
What this means for you: The effort it takes to slow the belt is exactly the effort that becomes usable power for your building.
Because the belt follows the runner, there are no speed buttons to chase mid-stride. Members speed up or slow down simply by changing how hard they run.
The console surfaces Your Speed against Target Speed so runners can hold a pace without guesswork.
What this means for you: First-time users pick it up quickly because the machine responds to effort rather than a control panel.
ECO-POWR™ units can be daisy-chained, so a row of treadmills can share an outlet. The manual caps how many go on one circuit by its rating: up to 9 units on a 230 V, 10 A circuit, or 8 on a 220 V, 10 A circuit.
What this means for you: A bank of treadmills needs fewer sockets; have your electrician confirm the circuit and layout for your site before fit-out.
The G660 connects to a standard power socket through its power cord, which carries the energy members generate back into your circuit. SportsArt specifies 220V / 50Hz with 20 W input and a maximum output of 200 W, and the unit also carries a built-in 12 V storage battery.
What this means for you: You are not rewiring the room to add these, but have an electrician confirm the circuit, particularly for a row of units.
For gyms, hotels and corporate sites chasing energy and carbon targets, this treadmill turns a cardio floor into an electricity source. It gives you measurable numbers to put in a sustainability report.
The Instant Watt To Grid readout makes that contribution visible to members and guests in real time.
What this means for you: This is equipment you can point to when a member or stakeholder asks what your facility is doing about energy use.

Effort: 9 steps in the manual (Step 0 to Step 8): fit the pedestals, handlebar and display, move and level the unit, centre and tension the walk strips, then fit the power cord. Tools: Allen wrenches, a flathead/Phillips screwdriver and a 22 x 24 mm open-ended wrench are supplied in the hardware kit.
The belt only moves when you drive it, so your effort sets the pace. On the slat surface you push from the hips and land under your body to keep it moving. In my coaching career I've found members either love the honesty of it immediately or need a few sessions to adapt. It rewards good form and exposes lazy strides fast.
Yes. The ECO-POWR integrated inverter turns your effort into electricity and feeds it back into the building's circuit through the power cord, at up to 200 W maximum output, while the unit itself draws 20 W input. The console shows Human Watts and Instant Watt To Grid so members see their output live. How much you generate depends on how hard and how long people train.
ECO-POWR units can be daisy-chained so several share an outlet. The manual limits how many go on one circuit by its rating: up to 9 units on a 230 V, 10 A circuit, or 8 on a 220 V, 10 A circuit, with each unit putting out up to 200 W. Have your electrician confirm the circuit and layout at fit-out.
It suits commercial gyms, 24/7 franchises, hotels, studios and serious home setups wanting user-powered conditioning. The user weight range is 45 to 150 kg and speed runs from 3.0 to 20.0 km/h on a fixed 7% (4°) incline. Not the pick for light, casual walking; it earns its keep with sprint intervals, sled-style pushes and higher-intensity training.
The unit measures 215.7 cm long, 84.1 cm wide and 157.2 cm high, with a 147.3 x 48.3 cm running area. At 157.2 cm tall it sits well under a standard 2.4 m ceiling. It weighs 214 kg, so plan a permanent position on a solid floor and leave clear run-off space behind it for safety.
This carries a full commercial warranty: lifetime on the frame, 3 years on parts, 3 years on wear items and 3 years labour. High wear items are covered 90 days with no labour. Warranty is handled by an Australian servicing team, which matters when a unit is part of a working commercial fleet.
