The Invacare Top End Force G Handcycle is a jet. The Force G Handcycle’s design offers an adjustable, trunk-powered, erect position for athletes that have a low paraplegia, amputees and competitors who can “gut” it out using abdominal, arm, shoulder and chest muscles. The Force G Handcycle can be considered a cross trainer and is used by athletes classified as an H4 or H5. It is a great core workout and allows you to see the traffic a bit easier than the recline-only positioned handcycles.
