Le cadre est plié, et les deux extrémités du cadre sont couplées ensemble et forment un siège convexe. Les fourches avant et arrière placées du même côtés n'ont qu'une tige. Quant aux roues avant et arrière elles sont convexes lorsqu'elles sont orientées vers les fourches avant et arrière et le diamètre externe de la première correspond au diamètre interne de la seconde. La manivelle est divisée en deux parties, la partie terminale qui est reliée de manière rotative à la pédale et la partie principale qui est reliée de manière rotative à la partie terminale par le biais d'un boulon.
