The invention relates to a modulable sled comprising a shell having an outer slide structure and an inner seating structure for at least one user. The seating structure has two lateral walls each extending vertically on either side of the seat. The sled has a brake device which is actuated by at least one handle mounted on one of the lateral walls. The sled also includes a module having an alternative seating structure, with the module being arranged to be able to be reversibly mounted in the shell by covering its seating structure and creating an alternative seating configuration on the sled. The module also has at least one lateral structure which, when it is mounted in the shell, is arranged to prevent the actuation of the handle of the brake device.

An ice fishing sled comprising a plastic tub body with raised walls, and flotation bumpers secured to the exterior of the walls of the tub body around the upper edges of the walls to form a peripheral flotation shelf extending outwardly from the tub body. Bottom surfaces of the flotation bumpers are spaced above the bottom of the tub body, and can function as integral raised runners along the sides of the sled when encountering deep snow or uneven ice. The tub may optionally have a peripheral flange or lip extending outwardly from the upper periphery of the tub walls, with the peripheral flotation shelf located beneath and adjacent or against the underside of the flange or lip.

A vehicle brake actuated to stop a vehicle drive system upon separation of the rider from the vehicle by a threshold distance and/or upon power being cut to the vehicle ignition. Thus, the proximity device is sensitive to the proximity of a rider to the vehicle. The brake includes an actuator and a switch. The brake actuator applies a braking force to a vehicle drive member. The proximity device triggers the switch to provide an activation signal to the brake actuator upon a determination of crossing a pre-set proximity threshold. Stoppage of engine ignition may also activate the brake.

A snow raft comprises a plurality of adjustable speed control studs to control the speed of the raft wherein adjustments are made by way of threading and unthreading the studs located within threaded sockets.

A ski bike for gliding across a slick surface that dampens shock forces on skis and provides precise maneuverability on a slick surface. The ski bike is configured to turn through either: a rotatable handle bar sub assembly, by shifting the weight of the rider, or through a carving technique involving digging the skis into snow and following the formed carved path to turn. The ski bike dampens shock forces on the skis through a dampener that absorbs shock forces from a front ski, a front shock pivot mount that that enables lateral pivoting to absorb lateral shock forces, and a swing arm tower that enables lateral pivoting of a pair of rear skis. A stomp plate provides stability by gripping footwear of a rider and enabling passage of moisture. A frame includes a lift bar that enables the ski bike to be lifted by ski lift.
