SPIRIT Fitness 4.0U Rehabilitation Upright Bike

The SPIRIT Fitness 4.0U Rehabilitation Upright Bike is designed for physical therapy, rehabilitation, and commercial healthcare environments where controlled resistance, patient comfort, and reliable performance are essential.

Featuring self-generating power, the SPIRIT 4.0U provides cordless operation without the need for an external power source, offering greater flexibility when positioning equipment within a rehabilitation or therapy facility. An electromagnetic resistance system provides 40 levels of resistance, allowing clinicians to adjust exercise intensity to accommodate different stages of rehabilitation, mobility levels, and conditioning goals.

The SPIRIT 4.0U combines a comfortable high-density foam seat with fore/aft and vertical adjustment, oversized fast-latching pedals, and supportive upper handlebars to create a stable and adaptable platform for therapeutic exercise. With a 440 lb. maximum user weight, commercial-grade steel frame, and recommended user height range of 4'10" to 6'6", the 4.0U is built to accommodate a broad range of users.

Designed for Rehabilitation & Physical Therapy

The SPIRIT Fitness 4.0U combines the familiar positioning of an upright exercise bike with features designed to support rehabilitation and therapeutic exercise.

Its upright riding position encourages proper posture and alignment, while the adjustable seat helps clinicians establish an appropriate riding position for individual users. With 40 resistance levels and a workload range of 10 to 750 watts, exercise intensity can be progressively adjusted based on the user's abilities and rehabilitation goals.

Self-generating power eliminates the need to position the bike near an electrical outlet, providing additional flexibility for physical therapy clinics, rehabilitation departments, and other professional healthcare environments.

Cordless operation provides greater flexibility when arranging rehabilitation equipment and can help reduce the number of power cords and electrical connections within a clinical environment. This allows the bike to be positioned where it best supports the facility's treatment and exercise space.

40 Levels of Resistance

An electromagnetic resistance system provides 40 resistance levels, giving clinicians and users precise control over exercise intensity.

With a workload range from 10 to 750 watts, the SPIRIT 4.0U can accommodate everything from lower-intensity therapeutic exercise to progressive cardiovascular conditioning as a user's strength and endurance improve.

Adjustable Seating for a Wide Range of Users

The high-density foam seat can be adjusted vertically and horizontally (fore/aft) to help establish a comfortable and appropriate riding position.

Designed for users ranging from approximately 4'10" to 6'6", the adjustable seating system makes the SPIRIT 4.0U adaptable to a broad patient population within physical therapy and rehabilitation environments.
