ABSTRACT:
A close-coupled tandem bicycle is described with a shorter wheelbase than a standard tandem bicycle and with the front and rear riders positioned closer together for easier communication and interaction between them. Two pedal cranks drive the rear wheel through a sprocket-and-chain drive. Both the front and rear passenger can steer the bicycle. A main handlebar with long handgrips extends rearward within easy reach of the rear passenger. A secondary handlebar attaches to the main handlebar and extends in front of it for use by the front passenger. The height and forward extension of the secondary handlebar is adjustable independently of the main handlebar so that both passengers can adjust the seat and the handlebars to their liking. The tiding positions can be adjusted to allow two riders of different sizes, such as a child and an adult, to ride together in comfort. The close-coupled seating arrangement gives a child riding in the front seat a greater sense of safety than the head-to-tail arrangement of standard tandems. A blind or handicapped passenger can also ride in the front or rear position and truly participate in steering and controlling the bicycle with the increased sense of security of having another rider in close proximity. The fore-and-aft adjustability of the riding positions also allows two riders to move very close together so that they can ride in a closer, almost intimate, riding position perfect for taking romantic bicycle rides together.
