This invention contains different designs of ski, snowboard, and wheel supports that attach to an existing bicycle frame. The ski and wheel supports are interchangeable. This allows easy transformation of a bicycle to a ski bike, snowboard bike, electric bike, or pedal bike. Rider simply attaches the desired ski/wheel supports, depending on the activity desired. The brake and gear controls are easily changed out by replacing the entire steering bar. It saves people the necessity of buying and storing three different types of bikes. The bikes are also light weight and easily transported on the bike rack or lift.

A support assembly for use with snow sports boards includes a base configured to be attached to the snow sports board. A frame has a first portion extending downward and a second portion extending rearward from the first portion. A seat is mounted on the second portion of the frame. A shock absorber extends between the base and the first portion of the frame. During use, the support assembly is configured to support a rider sitting on the seat in a face-forward position with the rider's knees vertically below and forward of the rider's hips.

A snowmobile has a frame, a ski connected to the frame, a seat connected to the frame for accommodating a driver of the snowmobile, a rear suspension assembly operatively connected to the frame, 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 rear suspension assembly has a suspension assembly drive axle defining a drive axle rotation axis, and a drive sprocket mounted to the drive axle. The motor has a shaft rotatable about a shaft rotation axis. The drive axle rotation axis is positioned forwardly of the shaft rotation axis. The seat is positioned above the motor.

An apparatus for adapting a single-track vehicle for use on a chairlift is provided. A first adapter portion may be configured to be removably coupled to at least a portion of a single-track vehicle. A second adapter portion may be pivotably coupled to the first adapter portion. A space formed between the first adapter portion and the second adapter portion may be configured to receive at least a portion of a chairlift seat of a chairlift.

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 present invention relates to an apparatus for attachment to a slidable runner, adjustable between a folded configuration for transport or storage and an unfolded configuration for use, and tunable to match various terrain characteristics and user characteristics and preferences.

Disclosed is a support and suspension assembly for a snow sports board. The assembly includes a base configured to be attached to a snow sports board and a frame above the base. The frame includes a first portion extending vertically upward or upward and forward to an upper end. The frame further includes a second portion extending generally rearward from the upper end of the first portion. A seat is on the second portion of the frame. A shock absorber is connected between the base and the frame. A linkage assembly is pivotably connected between the base and the first portion of the frame.

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.
