A method of assembling two snowmobiles with a common frame includes providing a common forward frame. A first common component is provided and positioned at a first orientation or at a second orientation with respect to the common forward frame. The first common component is secured at the first orientation or at the second orientation. The method includes selecting between a first set of first model components and a second set of second model components and securing the first set of first model components or the second set of second model components.

The present disclosure relates generally to bicycles. In particular, the present disclosure provides systems and devices for converting a standard bicycle into a cargo bicycle using various detachable components. The ability to convert a standard bicycle into a cargo bicycle and back again confers many advantages, including eliminating the need for a separate bicycle for transporting cargo and encouraging the use of bicycles as a mode of transportation.

A powered wheeled riding device is configured to receive left and right foot inputs from a user and in response control a left motor and a right motor to move respective left and right wheels forwardly and backwardly consistent with the left and right foot inputs in order to steer the device without changing a direction of the wheels relative to a frame of the riding device. The riding device has at least one rear wheel that is not powered. The rear wheel is mounted on a wheel mount that rotates freely about a vertical axis so that the rear wheel freely is directed in any direction.

According to an aspect, there is provided a vehicle system that includes a foot-deck-based vehicle and a seat accessory structure. The foot-deck-based vehicle includes a foot deck, a handle structure and a plurality of wheels. The foot deck is positioned to support—a user and includes a first handle structure receiving feature. The handle structure is detachably connectable to the first handle structure receiving feature. The seat accessory structure has a seat body and is detachably connectable to the foot deck so as to form a seat-based vehicle. The seat accessory structure has a second handle structure receiving feature thereon. The handle structure is detachably connectable to the second handle structure receiving feature, so as to be positioned for gripping by a secondary person when the secondary person is urging the seat-based vehicle to roll on the ground surface while the user is seated on the seat body.

A bicycle for transporting loads and individuals, wherein the rear wheel is arranged with a first spacing from the front wheel and wherein the bicycle is constructed to be able to be adjusted in terms of length by the front wheel and/or the rear wheel being able to be moved from a first position into a second position so that the rear wheel and the front wheel in the second position are arranged with a second spacing from each other, wherein the second spacing is greater than the first spacing, and wherein the bicycle both with the first spacing and with the second spacing from the front wheel and rear wheel is ready to ride or can be ridden.

A vehicle may have a seat and front wheel similar to those of a bicycle. However, the vehicle may have two rear wheels. The position of the two rear wheels may be adjustable. When the two rear wheels touch each other, the vehicle may function as a bicycle. When they are moved apart, the vehicle may function as a tricycle. In tricycle mode, the vehicle may travel autonomously without a human rider. In bicycle mode, a human may ride the vehicle like a bicycle. To transition between bicycle and tricycle modes, each rear wheel may rotate about a horizontal axis that is parallel to a longitudinal axis of the vehicle. In some cases, a bike chain is connected to only one of the rear wheels. In bicycle mode, motion imparted by the chain to one rear wheel may be transferred to the other by friction.
