The invention relates to the fields of bikes or electric bikes which have no central shaft between wheels, can be quickly dismounted, can be driven by wheel rims, have reverse brakes, have quickly-lowered seat cushions, can be folded and have telescopic mud-and-water baffle plates. The bike or electric bike is mainly characterized in that a front wheel and a rear wheel adopt a plurality of limitation wheels and driving limitation wheels; the plurality of limitation wheels and driving limitation wheels are fixed to vertical rods and cross rods of a front wheel group and a rear wheel group; a big wheel of a transmission group is internally geared with a small wheel of the transmission group; a pawl structure is arranged between the transmission shaft and the driving limitation wheels, and the corresponding driving limitation wheel is used for driving the corresponding wheel rim of the rear wheel; a pedal group can be rotated 90 degrees along a rotary shaft and a straight line is formed by the pedal group and a connecting rod; when a push gear of a brake group is rotated clockwise to the lower part of a push plate, a homopolar magnet repel the push gear and direct contact between thepush gear and the homopolar magnet is avoided, and then, the push gear is pushed out by an elastic sheet, the push plate, a brake pad and the like can be pushed by the push gear during opposite rotation so as to brake the rear wheel; a handle of a quick-lowering group can be pressed so as to drive a brake line to ensure that a limiting pin is disengaged from a limiting groove of a seat rod, and the seat rod and the seat cushion can be quickly lowered; and the mud-and-water baffle plates mainly comprise coil springs and mud baffle plates made of flexible materials, and can be expandable; and afolding group mainly comprises a three-sided folding plate, a washer, a positioning plate and the like.

    本发明涉及一种车轮无中心轴可快拆、轮边驱动、反转刹车、座垫可速降、可折叠、泥水挡可伸缩的自行车和电动自行车领域,主要特征是:前、后轮用多个限位轮和驱限轮固定于前、后轮组的立杆和横杆上;传动组的大、小轮内啮合,传动轴和驱限轮之间有棘爪结构,驱限轮驱动后轮的轮边;脚踏组可沿转轴旋转90度与连杆成一条直线;刹车组的推挡顺时针转动到推板下面时被其上的同极性磁铁相排斥而不直接接触,过后推挡被弹片推出,反转时推挡推动推板、刹车片等刹住后轮;按压速降组的手柄,带动刹车线使限位销脱离座杆的限位槽,使座杆和座垫快速降低;泥水档主要有卷簧和柔性材料的泥档,可伸缩;折叠组主要有三面的折叠板、垫圈和定位板等。
