The Stamina WIRK Under Desk Bike is a desk exercise bike with quiet magnetic resistance that will not disturb co-workers. The low-profile design fits easily under a desk, preventing the user from banging their knees. The Stamina WIRK Under Desk Bike allows users to easily exercise without painful desk to knee interaction. Other under desk cycles require the user to carefully position to prevent banging their knees. This adapted desk bike provides more room for movement, and can also be used on top of the desk for an upper body workout. The textured pedals with straps keep the feet or hands secured. The magnetic resistance is silent and has eight levels of resistance to provide a challenging and effective exercise program. The wireless monitor displays the workout time, distance, calories burned and rotations per minute. The Stamina WIRK Under Desk Bike provides users a helpful solution to quietly and efficiently burn calories at work and be productive at the same time.
