The invention discloses a pedal sports bicycle which comprises a frame provided with a longitudinal beam arranged in the front-back direction and located in the middle of the frame; a pedal which is rotationally erected on the longitudinal beam and used for rotating with a longitudinal axis as the center, and the two sides of the pedal are used for being alternately treaded by a user; a longitudinal bevel gear which is connected with the pedal and is used for synchronously rotating along with the pedal; two driven bevel gears which are respectively arranged on two sides of the frame and are meshed with the longitudinal bevel gear; and ratchet wheels which are arranged on the two sides of the rear wheel, and the two ratchet wheels are in transmission connection with the driven bevel gears on the corresponding sides of the frame through chains. In the using process, a user alternately steps on two feet, the pressure on knees is small in the process, and the knee pad is suitable for middle-aged and elderly people with weak knees. When the pedal locks the bicycle and works in a sliding plate mode, the stability, the obstacle avoidance capability and the braking capability of the pedal locking bicycle are better than those of a sliding plate in the prior art due to the fact that wheels of the pedal locking bicycle are large and a brake assembly of an existing bicycle can be adopted, and the pedal sports bicycle is more suitable for teenagers to use.

    本发明公开了一种踏板运动自行车,其包括:车架,具有一个沿前后方向设置、位于车架中部的纵向梁;踏板,转动搭设在纵向梁上,用于沿一个纵向轴线为中心进行转动,两侧用于供使用者交替踩下;纵向锥齿轮,与踏板连接,用于随着踏板同步转动;两个从动锥齿轮,分别设置在车架的两侧,并与纵向锥齿轮啮合;后轮的两侧均设置有棘轮,两个棘轮分别与车架对应侧的从动锥齿轮通过链条传动连接。使用过程中,使用者两脚交替踩下,该过程对膝盖的压力较小,适合膝盖脆弱的中老年人使用。当踏板锁紧自行车工作与滑板模式时,由于其车轮较大,且可采用现有自行车的刹车组件,使其在稳定性、避障能力以及制动能力均好于现有技术中的滑板,更适合青少年使用。
