The MonoMano Cycling Control System are adapted tricycle handlebars intended for upper extremity amputees and others who have the use of only one hand, including stroke survivors and people with brain injury or arthritis. This handlebar is can be attached to any recumbent trike with a U-shaped handlebar that has a horizontal support beam. It attaches to the tricycle handlebar's horizontal support and extends back toward the trike's seat. The design enables a person to steer the tricycle comfortably with one hand, while operating both brakes and shifting through all gears without removing his or her hand from the grip. It is also padded for comfort and easy gripping. The MonoMano handlebar is adjustable so it can accommodate children and adults up to 76 inches in height.
