A snowmobile has a frame, a ski, a rear suspension assembly, an endless track supported by the rear suspension assembly, a motor supported by the frame, and a continuously variable transmission (CVT) operatively connecting the motor to the endless track. The motor has a shaft rotatable about a shaft rotation axis. The CVT has a primary pulley, a secondary pulley, and a transmission belt. The primary pulley is rotatable about a primary pulley rotation axis extending parallel to the shaft rotation axis of the shaft of the motor. The primary pulley is operatively connected to and driven by the shaft of the motor by one of a chain and a belt. The secondary pulley is operatively connected to and driven by the primary pulley. The secondary pulley is operatively connected to the endless track. The transmission belt connects the primary pulley to the secondary pulley.

The invention concerns a device for controlling a monoski (1), in particular for snow, by means of the combined simple rotation and simple tilting of a single control member such as a handlebar, simultaneously by lateral inclination and by longitudinal twisting. It therefore combines the necessary mechanical functions of a pair of conventional fixtures with the ease of use of a bicycle, and does not require a specific monoski. It makes it possible to move freely on the snow, controlling with both feet held but not locked, or indeed to use one foot to help push on flat terrain and provide stability. The lever arm provided by the control member is considerably superior to that of a pair of conventional fixtures, greatly improving ease of use and the maximum capacities of the device. Finally, it can be quickly folded for ease of handling and storage.

A vehicle has a frame, a ski, an endless track, a motor, a rear suspension assembly supporting the endless track, and a continuously variable transmission operatively connecting the motor to the endless track for driving the endless track. The continuously variable transmission has a primary pulley operatively connected to the motor, a transmission belt, and a secondary pulley operatively connected to the primary pulley via the transmission belt. The secondary pulley is operatively connected to the endless track. The continuously variable transmission is positioned forwardly of the motor.

In some examples, a ski bike includes a frame, a steering mechanism rotatably coupled to the frame, a ski, and a ski retention system. The ski retention system rotatably couples the ski to the frame or the steering mechanism. The ski retention system includes a ski bracket and a fixed member. The ski bracket is rigidly coupled to the ski. The fixed member is rigidly coupled to the frame or the steering mechanism and rotatably coupled to the ski bracket.

Embodiments for a ski scooter device are provided. The scooter includes a central ski, a central platform, two outrigger skis, a suspension system, and a steering mechanism. Generally speaking, these components are structured such central platform is attached on top of the central ski, the steering mechanism is attached to the central platform and the suspension system, and the suspension system is attached to the two outrigger skis.

The snow surface skimmer is provided with: a skimmer body; a steering handle, which extends upward at a slant from the skimmer body; a seat installed on a region of the skimmer body that is behind the steering handle; and a skimming board. The skimming board is detachably attached to the bottom surface of the skimmer body by a skimmer attachment mechanism so that the attachment position in the front-back direction is adjustable. A skimming board suited to the skimming person's body type, build, etc. can be attached to the skimmer body at the appropriate position in the front-back direction.

A board for downhill winter sports forgoes the use of bindings for holding a person in place. An elongated rigid frame receives a foot board on a top portion and a base board on a bottom portion. A steering board allows for a person to direction motion. The elongated rigid frame also receives a rotatable steering column, which is secured through an arm and steering collar. A bearing assembly, including inner race and outer race, allows for rotation of the steering column within the steering collar. The steering column has a control end which includes a first handle and a second handle that serve as a user interface. The steering column also has an actuation end, the actuation end being a fork which is mounted to the steering board. A person can use the handles to rotate the steering column and thus the steering board in order to change direction.

A snow vehicle is disclosed comprising a vehicle frame, a propulsion unit coupled to the frame, and a front ski steered by a steering mechanism. The front of the vehicle includes a first front suspension and a second front suspension coupled to the ski. The rear suspension includes a bumper assembly preventing bottoming out of the rear suspension. The rear suspension is coupled to the vehicle frame such that the longitudinal spacing between the vehicle frame and rear suspension is adjustably controllable.
