Systems and methods for an improved walker are provided. The inventive walker allows for greater control over the speed of the walker. More specifically, wheels having specific characteristics may be used to control the speed of rotation of the wheels. For instance, the wheel may include an inner wheel assembly including a coil or coils, and an outer wheel assembly including a magnet or magnets. A magnetic field may be created using current through the coils, which in turn limits the speed with which the outer wheel assembly can be rotated relative to the inner wheel assembly. The present invention also includes a control system used to control the speed and other characteristics of the walker. The present invention may also collect associated data and display of the same which can help determine future activities associated with the walker.
