NOVELTY - The tricar has two rear wheels and one front wheel, and a frontal chassis on which a solar panel (A) is positioned, where the tricar is foldable. A handlebar is connected to the front wheel (4). The panel charges two accumulators (7, 8) supplying power to an electric motor (9) connected to an inverter (6). A saddle is placed in a cavity and is blocked in a defined position after unfolding the tricar. Belts and reduction gears are arranged to engage the motor and the drive wheel. A handle has a clutch system that separates a drive wheel from the motor.    USE - Tricar e.g. three wheeled lightweight motor cycle, for being drawn as a suitcase-trolley and stored in a boot of a car (claimed).    ADVANTAGE - The tricar is foldable so that it can be used as a suitcase-trolley and stored in a boot of a car when it is folded. The tricar has reduced maintenance cost and permits to replace the accumulator that is not supplied with power by the other accumulator in an automatic manner while allowing the recharge of the accumulator not supplied with power. The handlebar connected to the front wheel permits to drive the tricar. The solar panel permits to charge the accumulators in an alternate manner. The solar panels supply the accumulators with solar energy, thus providing a non pollutant tricar. The handle has a clutch system separating the drive wheel from the motor in order to increase the comfort of the tricar for all operations. The shape and the size of the tricar permit to store it in a basket in the car. The tricar is supplied from a traditional charge system by electrical sockets in the car and in the electrical network of the building when the solar panel does not ensure the charge of the accumulators. The belts and the reduction gears are arranged to engage the motor and the drive wheel in order to provide a speed and a sufficient power to the tricar.
