The present invention of pipe-bending apparatus includes: a frame, a bending shoe having gear teeth and concave groove on its outer circumference, a drive-gear, a gear rack having gear teeth and concave groove on one surface and gear teeth only on opposite surface. The frame pivotally supports bending shoe and drive-gear, positions gear rack engaging bending shoe and drive-gear. When using the pipe-bending apparatus, a straight pipe is laid inside the groove on gear rack with one pipe portion secured to bending shoe. Force is applied to turn drive gear, with all gear components engaged, gear rack and pipe transverse downwards and turns bending shoe. With one pipe portion secured to and turning with bending shoe, the pipe begins bending inside the concave groove on bending shoe.
