A pedaling apparatus (10) including a frame assembly having a front and a rear sections with a hollow seat tube (12), and a seat post (18) supported by said seat tube (12). The seat post (18) has attachment means for attaching a seat (16). The seat post (18) and the seat tube (12) are supporting the seat (16) at an adjustable position relative to the rear section. The seat tube (12) has a substantially curved part to accommodate therein a compatible curved part of the seat post (18). The curved parts of the seat tube (12) and the seat post (18) are configured for telescopic adjustment of the position of the attached seat (16) along a curved trajectory path extending upwardly and rearwardly relative to said rear section to suit users of different heights and physiques. The apparatus (10) may have a pair of pedals (26) arranged so that the user is sitting in a substantially upright pedaling position on the seat and is far enough behind the pedals (26) to give the legs an uncramped and efficient pedaling action.
