Sets of magnet assemblies coupled to the undercarriage of an amusement kart are provided. Each of the magnet assemblies can include: a suspension component coupled to the undercarriage; magnetic material coupled to the suspension component; and a rotating component coupled to the suspension component. Other sets of magnet assemblies can include a skid component coupled to the suspension component. Amusement park attractions are provided that can include: an amusement kart having one or more magnet assemblies coupled to an undercarriage of the amusement kart; and a track comprising iron plating sufficient to magnetically engage the one or more magnet assemblies. Amusement karts are also provided that can include: a frame supported by front and rear wheels; and complimentary side rails extending along both sides of the frame and between the front and rear wheels.

Some implementations can include a zero turn radius utility vehicle that is operated in a standing position by an operator using foot controls provided on the utility vehicle. Accordingly, the operator's hands are free to operate handheld equipment (e.g., a line trimmer, edger, blower, etc.) while the operator controls the utility vehicle via the foot controls. Further, the utility vehicle may have a single third wheel (and no mower deck or other deck or protrusion) extending from the front of the vehicle frame so as to minimize any protrusions to the front of the vehicle, which can permit the operator to work on the ground in front of the utility vehicle using handheld equipment without interference from a mower deck, while remaining in a standing position on the utility vehicle and being able to simultaneously control the utility vehicle (via foot controls) and perform work with handheld equipment.

An electric vehicle may comprise a board including deck portions each configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. A motor assembly may be mounted to the board and configured to propel the electric vehicle using the wheel assembly. At least one orientation sensor may be configured to measure orientation information of the board, and at least one pressure-sensing transducer may be configured to determine rider presence information. A motor controller may be configured to receive the orientation information and the rider presence information, and to cause the motor assembly to propel the electric vehicle based on the orientation and presence information.

An apparatus controller for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle. The apparatus has an input for receiving specification from the rider of a desired direction of travel, and indicating means for reflecting to the rider a propitious instantaneous body orientation to enhance stability in the face of lateral acceleration. The indicating may include a handlebar that is pivotable with respect to the vehicle and that is driven in response to vehicle turning.
