A riding exerciser includes two curved base frames, two parallel seat supports pivoted to the curved base frame in the middle to support a seat, a lower actuating rod having a top end pivotally connected between the curved base frames at the top and a bottom end fixed with a U-tube to hold a pair of pedals, an upper actuating rod pivoted to the lower actuating rod to hold a handle, and a link connected between the lower actuating rod and the seat supports, wherein the upper actuating rod has a series of lock holes on a bottom sector plate thereof for locking in any of a series of angular positions by a spring-supported lock bolt on the lower actuating rod; the lower actuating rod has a horizontal socket with a radial slot at the top, through which a headed screw is inserted and threaded into a screw hole on the handle to limit the rotating angle of the handle relative to the horizontal socket.
