The Xebex AirPlus Runner Smart Connect is a non-motorized, self-generated, curved treadmill. It uses no electricity and instead runs on the energy produced by the runner’s own movement on the treadmill. Beginners and competitors can run at desired speed and change output at will with no maximum or minimum speed setting. Further, the AirPlus lever allows users to adjust the resistance from level 1 up to level 8 for added resistance. Use our multi-grip handlebar to mimic sled drives in various handle grip options.
