Abstract
For a baby stroller, an add-on assembly comprises a planar rectangular chassis pivotally attached to the stroller rear axle and carrying on its distal end a drive shaft with wheels. The chassis also mounts an electric motor having a spur gear engaging a ring gear in one of the wheels. At least one strut is connected at one end to the structure of the stroller well above the axle and at the other end to the rear of the chassis. The strut holds the chassis downward so that the drive wheels engage the pavement, supplanting the stroller rear wheels. Battery and controls for the motor are included.
