Abstract
A cycle exerciser has a pedal-actuatable drive shaft and a pair of counter shafts rotatably mounted about spaced, parallel axes. First and second sprockets are mounted on the drive shaft and on one of the counter shafts, respectively. Third and fourth sprockets are mounted on the other counter shaft. A fifth sprocket is connected to an energy-absorbing wheel. The first and second sprockets are the same size and larger than the third sprocket. The fourth sprocket is larger than the fifth. A pair of oscillatable handle bar levers are connected to drive crank arms at opposite ends of the one counter shaft. A primary endless chain is in wraparound connecting engagement with the first, second, and third sprockets. A secondary endless chain is in wraparound connecting engagement with the fourth and fith sprockets. Energy is applied to the wheel through foot pedals and/or the handle bar levers.
