ABSTRACT:
A cycle in the form of a bicycle or a tricycle has an elongate horizontal main frame member with a rear wheel support assembly at the rear end and a front wheel support assembly at the front end. The front wheel support assembly supports the steerable front wheel at the lower end of a slanted steering column and handlebars at the top end slanted toward the rear. A seat and seat back are supported on a rearward-slanting seat standard that is clamped onto the horizontal frame member and may be adjusted fore and aft to provide comfortable access to the pedals mounted on the front end of the horizontal frame member. The seat remains at the same elevation regardless of the adjustment and the pedals are forward and below the hips of the rider. Force on the pedals forces the back against the backrest for enhanced leverage.
