Abstract

L'invention concerne une bicyclette électrique légère qui inclut un cadre de véhicule, une poignée, une roue avant, une roue arrière et un dispositif d'entraînement. Ledit cadre de véhicule inclut un tube transversal creux. Lesdites roue avant et roue arrière sont respectivement reliées au cadre de véhicule grâce à des roulements. La poignée est fixée sur une fourche avant. Ledit dispositif d'entraînement inclut un moteur à courant continu magnétique permanent à aggloméré mince, un système d'énergie accumulée et un contrôleur. Le système d'énergie accumulée est disposé dans le tube transversal. Ledit moteur à courant continu magnétique permanent est fixé sur un côté de roue d'entraînement. Un arbre de moteur est fermement relié à un pignon. Un engrenage en prise avec le pignon est disposé sur un côté de la roue d'entraînement. La bicyclette légère peut être entraînée électriquement. De même, la bicyclette peut être utilisée en tant que véhicule de cambrage en supprimant le siège et en faisant en sorte qu'une personne se tienne debout sur celle-ci. Le moteur peut générer de l'électricité et fournir de l'énergie grâce à l'oscillation du corps de la personne. De ce fait la bicyclette peut avancer.
