The invention provides a telescopic foldable
crawling ladder treading power generation rechargeable
automatic control type
electric bicycle. After a
smart phone authorized by a rider is taken away by a long distance, a circuit is turned off automatically, when the
smart phone vibrates after being taken away by a long distance or a storage battery leaves a control cabinet, a mobile communication apparatus automatically sends shot photos to the authorized
smart phone and displays the position of the mobile communication apparatus and images of the position, after stretching, the number of saddles is increased from one to three, after the two ends are folded by 90 degrees, a bicycle frame becomes symmetrical and can be erected on the ground vertically, a gravity induction oblique speed limiting switch automatically controls a right speed regulating rotary
handle and a foldable
towing speed regulating rotary
handle, a speed regulating
handle is rotated, an electric rear wheel is gradually supported upwards by a ladder crawler, so that the electric rear wheel is towed or goes downstairs, power is generated in the treading and braking processes, the phone and a computer can be charged, songs and communication information can be played, and an automatic prompt function is achieved when the
electric bicycle turns; and when a vehicle moves rapidly near the rear end of the bicycle in the riding process, the right speed regulating rotary handle vibrates, a rear stop lamp emits flickering strong light, and alarm sounds are given out by the mobile communication apparatus.
