Adrian Disney's Greenspeed Hand-Cranked Trike
To summarise, my hand-cranked Greenspeed is excellent. As a wheelchair dependent paraplegic it not only allows me to get out on the open road it also allows me to get off the open road (foot and mouth permitting). Inevitably the drive wheel does spin in the mud sometimes and getting off to push is a messier proposition for someone who has to sit in the mud than someone who has to stand in it. This is a small price to pay for the freedom the trike gives me to get to places that a wheelchair just won't go, at a speed that would give a wheelchair an inferiority complex. Despite the appearance in the attached picture, from my Tasmanian holiday, my machine does have three wheels.
