Talk to a treadmill specialist| Running surface | 1700 mm x 440 mm (L x W) |
| Max user weight | 170 kg |
| Warranty | 8 year frame, 12 months parts replacement |
Studios and 24/7 franchises running high-throughput conditioning classes need a treadmill that keeps pace without drawing power, and the Corsair FreeRun 105 runs entirely self-powered with a 15 degree curved slat deck and 8 levels of magnetic resistance. Its 1700 mm by 440 mm running surface and 170 kg max user weight suit continuous multi-user sprint and interval work.
It fits operators who want zero cabling and no floor power outlet, since members control the speed with their stride and the large LCD tracks time, speed, distance and calories. The 165 kg frame stays planted through sled-style pushes and quick interval sessions.
Self-powered and belt-free, this curved slat treadmill sets pace by where you stand: lean forward and it accelerates. Members feel the deceptively hard workout within minutes, which is what makes it earn its floor space.
The 170 kg user limit and 440 mm belt suit most, but taller sprinters will find the width snug. Site it near a wall for the 197.5 cm footprint on busy floors.

The rubber-surfaced slat belt is built for continuous multi-user traffic, so it holds up under back-to-back sessions in a busy gym or studio.
The rubber running surface gives grip underfoot at any pace, from a walk to a full sprint.
What this means for you: For a commercial floor, the slat belt is the part that takes the daily punishment, and this one is specified for it.
The runner drives the belt, so there is no motor to power, plug in or wire into the room. That removes the single most common service item on a motorised treadmill.
For fit-out, it means you can place units anywhere on the floor without planning around power outlets.
What this means for you: For operators, fewer electrical components mean fewer things that can fail and pull a unit off the floor.
The 15-degree curve puts the runner on the balls of their feet and lets them set the pace by where they stand on the deck. Move forward to speed up, drift back to slow down.
In practice, it encourages a mid-foot strike rather than heel-first landing.
What this means for you: The curve is the whole point of this machine: the runner, not a motor, decides how hard the session is.
Eight magnetic resistance levels let the runner dial the effort up for sled-style pushes or drop it back for easy recovery running.
It broadens the machine's range from steady aerobic work through to hard interval sets.
What this means for you: One machine covers a wide effort range, which matters when several members share it across a day.
There is no top speed cap set by the machine. The runner controls the pace directly through their stride, so sprint work is only limited by the athlete.
That makes it a genuine option for conditioning and interval training, not just steady cardio.
What this means for you: For athletic training clients, the ceiling is the runner's ability, which is exactly what a coach wants.
The large LCD display tracks the readouts a runner actually watches: time, speed, distance and estimated calories. Quick interval settings let staff or members start a structured session without menu-digging.
It is a straightforward, readable console rather than a screen loaded with features nobody uses.
What this means for you: On a busy floor, a simple readable console means less staff time spent explaining the machine.
At 165 kg, the frame is heavy enough to stay planted through hard sprint efforts without shifting across the floor. It supports users up to 170 kg.
The mass is part of the design: a curved treadmill needs a stable base to feel solid under a running load.
What this means for you: The weight that makes it awkward to move is the same weight that keeps it steady when someone is running flat out.
The assembled unit measures 197.5 cm long, 85.5 cm wide and 158 cm high, so it sits well under a standard 2.4 m ceiling. It arrives partially assembled in a wooden crate with instructions included.
Plan the floor space around the length: a curved treadmill needs clearance behind for safe dismount.
What this means for you: Confirm the run of floor space, not the ceiling, when you plan where these will go.
Warranty depends on how the machine is used. Domestic use carries an 8 year frame warranty plus 12 months parts replacement; commercial use is covered by 12 months frame and parts.
With no drive motor in the picture, the mechanical simplicity of a self-powered unit is part of what keeps it on the floor.
What this means for you: Match the warranty term to your setting before you order, and ask us for a quote on fleet or multi-unit orders.

Effort: a one-person job, see manual for a first build.
There's no motor and no power cord. You drive the belt yourself, so speed is entirely user-controlled, from a walk to a flat-out sprint. The 15 degree curved slat deck means your footstrike sets the pace. Step toward the front and it speeds up, drift back and it slows. It takes a session or two to feel natural, then most runners never look back.
The assembled footprint is 197.5 cm long by 85.5 cm wide, and it stands 158 cm tall, so a standard 2.4 m ceiling is no issue. Leave clear run-off space behind it and room either side for safe mounting and dismounting. It's a fixed frame, so confirm the spot is permanent before you commit the floor.
It's built for continuous multi-user settings: commercial gyms, 24/7 franchises, HIIT and functional studios, and serious home runners who want sprint work without a motor limiting them. Max user weight is 170 kg. Casual walkers looking for a simple stroll won't get the value from the curved deck, but for interval and conditioning work it earns its keep.
The magnetic resistance has 8 levels, so you can dial the belt from an easy free-run up to a heavy sled-style push. Lower levels suit steady running and endurance; higher levels turn it into a strength-endurance tool for pushing hard over short bursts. That range is what makes it a genuine conditioning station rather than just a treadmill.
It ships in a wooden crate and weighs 165 kg, so it arrives as freight rather than a parcel courier. Have clear access to the room planned before delivery day and a couple of people on hand to move the crate into position. We can talk through installation and depot options when you request a quote.
Take photos before you unpack anything and email them to support@cardioonline.com.au within 48 hours of delivery. We lodge the freight claim, organise replacement parts or a full unit, and stay across it until you're up and running. You don't chase the courier or the manufacturer yourself, that's our job.
It arrives partially assembled with instructions in the crate, so it's a one-person job to finish off. Give yourself a bit of extra time on a first build and work through the manual step by step. Because the unit is 165 kg, have a hand nearby to help shift it into its final position once it's together.
For home use you get an 8 year frame warranty and 12 months parts replacement. In a commercial setting it's covered by 12 months frame and parts. All warranties are local Australian cover handled by us, so if something needs sorting you deal with our team here, not an overseas manufacturer.
