A four wheel stepper bike having a body with an internal chamber containing a drive mechanism for transmitting power to a wheel, a steering linkage, and a brake. Foot pedal units on opposite side of the body are moved by an operator's feet to apply force to the drive mechanism. A steering column with handles hinged to the body and connected to the steering linkage is selectively movable to steer the bike and move between upright and folded positions. Bumpers attached to an end of the body support the bike in an upright position on a support surface when the steering column is in the folded position.
