A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. Since an essential feature of treadmill is the concave shape of the running surface of belt in its respective upper portion, the treadmill configurations insure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers.

An extensible roof for vehicles such as scooter-type motorcycles is provided. The extensible roof protects the passengers of the vehicle from the inclement climate and is able to be retreated in the front part of the vehicle and to be opened in the case of rain, snow or at the passenger's will, covering him/them totally from said inclement climate by means of the surface formed by different plates of roof linked to each other through a sliding system. The proposed roof is of the type comprising a mobile transparent covering panel, slidable in an upward and downward direction characterized in that when folded, the higher border of said at least one covering panel is below the handlebar of the motorcycle.

An electric three wheeled vehicle includes a vehicle chassis supporting a vehicle operator seat or saddle. The vehicle chassis defines a storage region beneath the vehicle operator seat or saddle. One or more energy storage devices for powering one or more electric motors of the vehicle are located within the storage region and are supported by the chassis. The storage region and/or the energy storage device(s) each form an elongate three-dimensional volume having a long axis that is parallel to a longitudinal axis of the vehicle.

The present invention relates to a vehicle, comprising a vehicle body, in particular a self-supporting vehicle body, wherein the vehicle comprises at least one drive which can be supplied by an energy store; and has a front wheel axle and a rear wheel axle. Furthermore, the vehicle has a steerable or steering axle and a steering module, wherein the steering axle is configured or defined by way of the steering module and extends, in particular, within the steering module, wherein the steering module has at least one wheel and preferably two wheels which are arranged coaxially with respect to one another, wherein the vehicle has or forms a steering axis and is configured in such a way that the steering module can perform a pivoting or rotational movement about the steering axis, and wherein the vehicle is configured in such a way that, as a result of the performance of the rotational movement of the steering module and with the support of the wheel or the wheels of the steering module on a roadway being maintained, a tilt movement of the steering axis in relation to the roadway is also performed, which tilt movement preferably leads to a tilted position of the vehicle in relation to the roadway.

These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.

Systems, methods and apparatus are provided through which in some implementations a motorized tricycle includes a lean mechanism and an active system that is operably coupled to the lean mechanism that receives an signal indicative of an interaction with human, that is operable to detect a lean of the body of the human and that is operable to receive a sensed movement on the seat via multisensory devices, and to generate and send a signal to the lean mechanism from the signal, the lean and the sensed movement.

A snowmobile includes a frame, at least one ski, a seat, a handlebar connected to the at least one ski via a steering shaft, and a single-piece hood. The single-piece hood includes a forward position located approximately equal to a first horizontal plane, a lower portion that extends rearwardly from the forward position and a top portion that extends rearwardly from the forward position, wherein the bottom portion is located beneath the first horizontal plane and the top portion is located above the first horizontal plane.

A motor scooter, for transportation of one person or multiple persons, includes a motoric drive. To provide a safe and comfortable motor scooter, which is environmentally-friendly, suitable for everyday-life and cost-effective, the motor scooter is connectable with various modules in a releasable manner. As such the motor scooter can include various and selectable module combinations.
