The invention relates to a bicycle and a bicycle saddle. The bicycle comprises wheels, the saddle, a brake mechanism, a control box and an auxiliary wheel device. The saddle is fixed on the control box through a first telescopic pull rod, the control box is connected with the brake mechanism through a second telescopic pull rod, and the top end of the first telescopic pull rod is connected with the bottom of the saddle; the auxiliary wheel device comprises an auxiliary wheel and a supporting rod, one end of the supporting rod is connected with the auxiliary wheel, the other end of the supporting rod is connected with a lifting rod, the other end of the lifting rod is connected with the tail end of the first telescopic pull rod, and the lifting rod is provided with a rotatable fulcrum. Compared with the prior art, according to the bicycle provided by the invention, when no rider exists, the brake mechanism abuts against tire surfaces or hubs on the wheels, so that tires cannot rotate, and when the rider rides the bicycle, the first telescopic pull rod drives a steel wire rope to pull up the brake mechanism and separate the brake mechanism from the tire surfaces or the hubs on the wheels, and therefore, the rider can ride the bicycle normally.

    本发明涉及涉及一种自行车及自行车车座,包括车轮、车座、制动机构、控制盒、辅助轮装置;其中,车座通过第一可伸缩拉杆固定在控制盒上,控制盒通过第二可伸缩拉杆与制动机构相连接,第一可升缩拉杆的顶端连接在车座底部;辅助轮装置包括辅助轮和支撑杆,支撑杆的一端连接辅助轮,支撑杆的另一端连接有升降杆,升降杆的另一端与第一可伸缩拉杆的末端相连接,升降杆设置有可转动支点。与现有技术相比,本发明提供的一种自行车,没有骑行者时,制动机构与车轮上的轮胎面或轮毂相抵接,这样可以使得轮胎不会转动,当有骑行者骑行时,第一伸缩拉杆带动钢丝绳将制动机构拉起,与车轮上的轮胎面或轮毂相分离,这样骑行者可以正常骑行。
