A frame for an electric bicycle, such as a long-tail electric cargo bicycle, is described. The bike frame, in some embodiments, includes cross members that connect a rear rack of the bicycle to a head tube of the bicycle via a seat tube of the bicycle. Via the multiple connection points, the cross members mitigate side to side movement, such as waggling, of the rear rack of the bicycle.

A vehicle for transporting persons and/or goods, having at least one frame which includes of at least one frame element which extends substantially parallel or obliquely to the longitudinal direction of the vehicle, at least one wheel carrier which can be detachably secured to the frame element and which, together with the frame element, forms a receiving region between the wheel carrier and the frame element. The wheel carrier and the frame element are spaced apart from one another at least in sections so as to form a cavity. The frame also includes at least one wheel unit which includes a wheel and can be fixed or is fixed in a rotatably mounted manner at least in sections in the receiving region between the wheel carrier and the frame element.

The present application is directed to motor driven vehicles. In one embodiment the motor driven vehicle is a trike that utilizes a customized three wheel rear truck assembly to create a completely novel riding experience. The rear truck assembly of the motor driven vehicle may be comprised of a skateboard truck and wheels along with a third center caster wheel on a custom caster assembly that allows the center cater wheel to rotate 360° independently from the outer skateboard wheels. The size parts of the motor driven vehicle may be varied in size, such as the wheels and mounting plates thereof, according to the needs of a rider. The center wheel may comprise a bracket assembly that holds the wheel at a fixed distance that is lower than the outer wheels.

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. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure 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. 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.
