The invention relates to the field of a bicycle or an electric bicycle with a wheel hub outer side driving reverse braking whistle bell, in particular to a bicycle with a front handlebar capable of rotating, driving the outer side of a rear wheel hub, pedal reverse braking and piston blowing sounding, and is mainly characterized in that a limiting wheel and a driving limiting wheel are mounted on cross rods of a front bracket and a rear bracket and are in contact with the outer side surfaces of the front wheel hub and the rear wheel hub; a large wheel and a small wheel of the transmission set are externally meshed, a pawl structure is arranged between the transmission shaft and a driving and limiting wheel, and the driving and limiting wheel drives the outer side face of a rear hub. A bull-eye universal wheel is mounted at one end of a bearing rod of the pedal group; when the large wheel rotates forwards, the protruding block makes contact with the idler wheel to enable the swing block to rotate backwards, and when the large wheel rotates backwards, the protruding block pushes the swing block to move backwards to achieve braking. Two ends of the muddy water baffle are elastic and are hung in grooves of the fixing rod, the bidirectional supporting rod, the central rod and the unidirectional supporting rod which penetrate through the front bracket and the rear bracket; the convex block on the folding plate is blocked by the positioning plate; and the bell group blows air to make a sound by overcoming the elastic force of the spring through the piston.
本发明涉及一种轮毂外侧驱动反转刹车口哨铃铛自行车或电动自行车领域,尤其是前把可转动、驱动后轮毂外侧、脚踏反转刹车、活塞吹气发声的自行车,主要特征是:前、后支架的横杆上安装限位轮和驱限轮与前、后轮毂的外侧面接触;传动组的大、小轮外啮合,传动轴和驱限轮之间有棘爪结构,驱限轮驱动后轮毂的外侧面;脚踏组的承重杆一端安装有牛眼万向轮;刹车组的摆块安装有滚轮,大轮正转时,凸块与滚轮接触使摆块后转,大轮反转时,凸块推动摆块后移而刹车;泥水挡的泥挡两头有弹性,泥挡两头挂在穿过前、后支架的固定杆、双向支撑杆、中心杆和单向支撑杆的凹槽内;折叠板上的凸块被定位板挡住;铃铛组由活塞克服弹簧的弹力吹气而发出声音。
