Abstract:
A tandem bicycle is provided that have a shortened wheel base between the front and rear wheels that allows a rider to ride comfortably alone from either the front or rear seats, or with a passenger in the front seat. The frame length of the inventive tandem bicycle is comparable to a standard single seat bicycle. The reduced proximity between riders, and the ability to steer for both the front or rear seats on the inventive tandem bicycle improves the level of participation and interaction between the riders. The wheelbase is reduced by bringing the front wheel closer to the front seat position. A reduced diameter front wheel is provided to accommodate rotational clearance of the front pedals thereby allowing two riders to ride on bicycle frame with a length common to single rider bicycle.
