A kind of electric bicycle arrangement for detecting, main system include vehicle frame, the seat for setting what vehicle frame and manipulation unit and gear unit. Preceding two side-line of Hou edge of what vehicle frame is respectively equipped with fork wheel unit, makes each fork wheel unit by extending centrally out and in the plural branch clamp arm that circumferencial direction is separated by, each clamp arm end of what is equipped with accessory whorl. By manipulating the manipulation of unit, make gear unit with the rotation of the accessory whorl of moving fork wheel unit, and then electric bicycle what flat road surface is enable to walk. Wherein, Hou edge is respectively equipped with radar detecting part before the vehicle frame system what, and what vehicle frame appropriate location is equipped with vibration detecting part and balance detecting part, road barrier is detected by radar detecting part what, or vibration detecting part is when detecting uneven ground, complex equilibrium detects part, drives the clamp arm of gear unit band moving fork wheel unit to rotate via microprocessing unit, and then enable the function of the climbing of electric bicycle composition or speeling stairway.一種電動代步車偵測裝置，主要係包含車架、設於車架之座椅及操控單元，以及傳動單元。於車架的前後緣兩側係分別設有叉輪單元，使各叉輪單元由中心向外延伸且在圓周方向相隔的複數支夾臂，於各夾臂端部設有副輪。藉由操控單元的操控，使傳動單元帶動叉輪單元之副輪的轉動，進而使電動代步車得以於平坦路面行走。其中，該車架係於前後緣分別設有雷達偵測件，並於車架適當位置設有震動偵測件及平衡偵測件，俾藉由雷達偵測件於偵測到路面障礙，或震動偵測件偵測到不平地面時，配合平衡偵測件，經由微處理單元驅使傳動單元帶動叉輪單元之夾臂轉動，進而使電動代步車得以構成爬坡或攀爬樓梯之功能。
