Abstract

Una bicicleta de doble tracción constituida por un cuadro triángulorectangular invertido, con el sillín desplazable horizontalmente en posición trasera, estando los pedales fijados a un disco ubicado en el interior de la rueda trasera, de la que puede desolidarizarse gracias a unos trinquetes y provisto en su periferia de un dentado sobre el que actúa un dispositivo de ejes y engranajes que transmite este movimiento a la rueda delantera, previéndose en ella la existencia de un trinquete mientras que todo el peso del ciclista se apoya sobre la llanta trasera gracias a la existencia de rodamientos de apoyo junto a los postes del cuadro, previéndose la existencia de otros rodamientos en el disco que aseguren su posicionamiento respecto a la llanta; presentando en la parte inferior trasera del cuadro un mecanismo con una rueda de apoyo al suelo que hace actuar un freno sobre la rueda trasera.
