A trailer for use with off-road vehicles such as all-terrain vehicles and snowmobiles. The disclosed off-road trailer can be adjusted to accommodate different trailer beds and attachments that can be readily off loaded and can be compactly packaged for shipping and storage. Modules for different conditions (e.g., ground or snow surface) can be implemented for multi-season usage. The disclosed suspension assembly enhances performance and robustness while maintaining cost effectiveness. The utility of the disclosed off-road trailer may be enhanced by grab handles for manual maneuvering, a rear bumper, and an active tail light. The overall design of the off-road trailer enables towing cargo behind a snowmobile or off-road vehicle over rough terrain at higher rates of speed than conventional off-road towable trailers.

In an aspect, a self-balancing two-wheeled vehicle is provided, having a body, and first and second wheels rotatably coupled to the body. The second wheel has at least one lateral roller rotatable about an axis that is one of oblique and orthogonal to a rotation axis of the second wheel. At least one motor is coupled to the second wheel to control rotation of the second wheel and the at least one lateral roller. At least one sensor is coupled to the body to generate orientation data therefor. A control module is coupled to the at least one motor to control operation thereof at least partially based on the orientation data generated by the at least one sensor.

Hybrid drive snowmobile comprising an IC engine, a variable speed drive comprising a first pulley connected to a drive shaft of the IC engine, a second pulley and a belt coupled to the first and second pulleys, an intermediate shaft connected to the second pulley of the variable speed drive, an output shaft connected to the intermediate shaft by a transmission and a drive wheel of a motor track of the snowmobile connected to the output shaft and a reversible electrical machine connected to the intermediate shaft.

A replacement bumper for a snowmobile ski is provided and methods for using the same. The replacement bumper has an abutment surface that makes contact with a spindle of a snowmobile in order to increase the contact surface area of a rear portion of a snowmobile ski and the ground and/or increase the weight being distributed on the rear portion of the snowmobile ski, which prevents the darting or tracking of the snowmobile ski. Also, includes is a method for removing an OEM bumper from a snowmobile ski assembly and installing a replacement bumper into said snowmobile ski assembly.
