Abstract
A recumbent bicycle is powered by the driving of a crank spindle that rotates on an axis generally coincident with that of the front wheel. The crank spindle is disposed within a spindle housing supported from the front of the bicycle frame, and the spindle housing supports the front wheel through a steerably turnable intermediate hub. Steering of the handlebars causes the front wheel to turn to steer the bicycle, while the crank spindle remains in a fixed orientation to the frame so that the bicycle can be continuously driven with pedals connected to the crank spindle, which in turn is connected to the rear wheel through a sprocket and drive chain assembly.
