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.

A transmission apparatus which reverses transport gears, including a third transmission shaft provided with a plurality of third transmission members each of which is configurable between a non-selected condition and a selected condition. Furthermore, the apparatus comprises a second transmission shaft provided with a plurality of second transmission members axially arranged at a respective third transmission member and engaged with the latter to establish a predetermined transmission ratio. An activation device is operationally associated with said third transmission members to configure at most only one in the selected condition to select the relative transmission ratio. Finally, the apparatus comprises a gear reversal member interposed between a third and a second transmission member both used for gear reversal so that said third transmission shaft rotates inversely with respect to the other transmission ratios.

A cargo bike transport carrier for transporting persons includes at least one seat element arranged inside the cargo bike transport carrier. The seat element is fastened via a holding means. According to a preferred embodiment, for ensuring good load transmission, the holding means are configured as a circumferential bracket and connecting bars.

A cargo bike transport carrier for accommodating cargo includes a bottom element, two mutually opposite side walls, a rear wall and a front wall. To allow for an inexpensive and simple manufacture of the cargo bike transport carrier, according to a preferred embodiment, the latter is made up of two plastic parts each constituting half of the transport carrier, wherein the two halves are separated by a vertical parting plane.

A cargo bicycle which can be driven using muscle power and/or an electric drive, with at least one pick-up area in or on which or at least one swap body and/or an additional load can be or is positioned and with at least one driver area which is positioned in front of the pick-up area in regard to the direction of travel of the cargo bicycle and which includes at least one seat unit, one pedal unit, one steering unit, one flashing roof element at least over the driver area and one at least area by area limiting floor plate of a floor unit in the driver area in the direction of the travel surface. The floor plate and roof element include at least an area by area distance to one another which is at least the body size of an operator.

A scooter includes a front platform and a driver platform rotatably connected to each other and each having a planar surface. Wheels are rotatably connected to the front platform and the driver platform, and a motor is in at least one of the wheels. The front platform and the driver platform are relatively rotatable between a stowed position in which the planar surfaces are in separate planes and a cargo position in which the planar surfaces are coplanar.
