    摘要: An exercise cycle of the invention includes a frame, a seat, a pedal assembly, an air-resistance device, and a movable handlebar assembly. The crankshaft of the pedal assembly is attached to a first gear which is then in turn mechanically linked to the second gear and pivotally attached to the handlebars to cause an oscillating synchronous motion upon operation of the pedal assembly.
