A vehicle is disclosed. The vehicle may include a base portion and a modular portion. The base portion may be a four wheel vehicle having an operator area with seating for at least two occupants in a side-by-side arrangement. The modular portion may be coupled to the base portion resulting in a six wheel vehicle. The wheels of the modular portion may be powered by an engine of the base portion.

A portable towing system for a motorcycle or similar vehicle, such as a trike, the frame of which can be lowered to ground level to facilitate loading of the motorcycle or similar vehicle by pushing or riding the vehicle onto the frame without risk of the vehicle falling off the sides of a steeply inclined ramp. The towing system may be assembled, raised, lowered, and disassembled by a single person, if desired. The towing system also comprises a cargo box to store the frame when disassembled. The raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies, and at least three heights of the frame are achieved by rotation of the lifting and lowering mechanism of the wheel assemblies. The cargo box and the frame can use the wheel assemblies interchangeably.

A side by side vehicle is disclosed having a vehicle frame having frame tubes extending from a front to a rear. A vehicle seat frame is positioned in a mid portion of the frame, and positions a seat frame at a raised position relative to the frame tubes. A powertrain is positioned rearward of the vehicle seat frame and is coupled to the vehicle frame. Side by side seats are supported by the seat frame; and one or more storage units are positioned under the side by side seats. The side by side vehicle also has a rear suspension comprising at least one rear alignment arm coupled to each side of a rear of the vehicle frame, where the alignment arms are coupled to the vehicle frame at front and rear connection points. A distance between the front connection points is greater than a distance between the rear connection points, and at least a portion of the powertrain is positioned between the front connection points of the alignment arms.
