Speedfit ProXL Non-Motorized Curved Treadmill

SpeedFit is the leader by being the original designer and first developer of the Curve Treadmill holding more than 10 Patents on the curve designed treadmills.

A motor-less treadmill that provides a better running experience than traditional motorized treadmills. Built for performance and high quality, this non-motorized and Curve Treadmill delivers an unparalleled running experience on this zero-maintenance treadmill.

These affordable and finest manual treadmills (Speedfit LITE and ProXL) are built to provide years of trouble free operation. Incorporated with various features, whether running that marathon training, or working on your fitness, these curved and non-motorized SpeedFit Products will provide that extra edge.

These motorless treadmills give the best cost benefit when compared to motorized treadmills. They are a lot more affordable than electrical treadmills and also more lightweight.


Once you run on the SpeedFit, you’ll never go back. The curve promotes proper posture and encourages the runner to lift their knees promoting a proper “ball of your feet” foot strike. The curve, combined with the frictionless cushioned slats absorb shock for a virtually no-impact workout. Walk, jog, run, sprint, or immediately stop. The ProXL instantly responds to you. The Speedboard ProXL has no speed limit!


The Speedboard ProXL is designed with a closed bearing system and a friction less slat belt, the end result is a smooth and quiet with zero maintenance required. The belt system requires no adjustments and has a lifespan of 150,000 miles, which is 10 times longer than the average treadmill. There is no need to replace the controllers or motors as with other treadmills because you are the motor!

The result is much like running outside – and isn’t that the point of it all?
There’s nothing else like it – it’s unique, indeed!

Step onto the Speedboard and the gravity of your own body brings it to life! Begin walking, step up a little further on the curved surface and begin running, step up even further and you can start to sprint, step backward and the Speedboard will stop. The Speedboard’s innovative, patented engineering provides a completely natural running experience – it’s the only treadmill that gives you the same control as leaving your front door — you dictate your pace not a machine!
