The Xebex Runner is a motorless, self-generated, curved treadmill. Using no electricity, and instead running on the energy produced by the runner’s own movement. Beginners and competitors can run at desired speed and change output at will with no maximum or minimum speed setting. Our 10mm thick, low-impact, shock-absorbing, vulcanized rubber running surface provides the runner with more comfort and less impact during long distance runs and all-out sprints. Proven to burn 30% more calories than traditional, motorized treadmills.
