A tandem exerciser is described with two facing seats and two pedal cranks that
cause tandem riders to face each other and pedal forwards. A mutually operable
handlebar crank with opposing handles mechanically couples to pedals on both sides
of the distal pedal crank. A single sprocket wheel concentrically attached to the
proximal pedal crank is coupled by a twisted, figure-eight looped chain to one
of two sprocket wheels coupled to the distal pedal crank. These opposing sprocket
wheels are mounted to their respective pedal cranks so as to have opposite offset
angles relative to vertical plane of frame. These offset angles prevent damaging
physical contact between sides of chain. The remaining sprocket wheel of distal
pedal crank is conventionally chain coupled to freewheel coupled to hub of flywheel.
Optionally, a power generator is belt-coupled to outer rim of flywheel, to produce
electrical, fluidic or motive power.
