A golf trike that has a slot between two storage compartments between its rear wheels. The slot fits and holds the front tire of a towed golf trike. A bag rack on the front golf trike articulates forward out of the way of the slot on the front trike to allow the front tire of the rear trike to fit into the slot. When the golf trike is not towing another trike the bag rack articulates rearward to hold a golf bag for routine play.

The present disclosure provides a small mobility vehicle including: a base unit including a footplate and a plurality of driving wheels mounted on the footplate, a first column unit having a first plurality of links hinged to another link of the first plurality of links, wherein the footplate is coupled to a lower end of a lower link of the first plurality of links and steering handlebars are coupled to an upper end of an upper link of the first plurality of links, and a second column unit capable of being folded or unfolded that has a second plurality of links hinged to another link of the second plurality of links, wherein a lower end of a first link of the second plurality of links is hinged to the footplate and an auxiliary wheel is coupled to one end of a second link of the second plurality of links.

A compact mobility device has an adjustable drive mode. The device includes a base panel and a number of drive wheels rotatably provided at opposite ends of the base panel. The drive wheels are configured to rotate by receiving torque from a driving unit. A column is constituted by a plurality of links connected in series to be foldable and is configured such that a lower end of a lower link is rotatably coupled to the base panel with an upper end of an upper link being provided with a steering handle. An auxiliary wheel is provided between the links constituting the column and is configured to roll along with the drive wheels by coming into contact with a ground when the links are folded.

Provided is an accessory for a self-balancing board having two lateral foot-deck ends, each being coupled to a motor that drives a wheel in response to its orientation. The foot-deck has at least one sensor that is triggered when a rider is in a riding position thereon. The accessory includes a chassis, at least one travel surface-contacting element, a seat, and an engagement structure that releasably engages the self-balancing board. At least one sensor-triggering element is actuatable between an idle position and a triggering position, wherein the at least one sensor-triggering element triggers the at least one sensor. At least one control member actuates at least one of the engagement structure and the at least one sensor-triggering element to control the orientation of the lateral foot-deck ends. At least one manually actuatable actuator actuates the at least one sensor-triggering element between the idle position and the triggering position.
