Abstract

Improved bicycle, of the type comprising a frame of essentially triangular tubular profiles lying down, in whose forward vertex is welded a substantially vertical bushing of rotating coupling of a front fork and its corresponding wheel, while the lower vertex of the frame welds transversely two bushings, one of which rotates the bottom bracket coupling, which incorporates a ring gear integral in the turn, while the other bushing is rotary coupling of a swingarm that mounts the rear wheel, incorporating the rear wheel a pinion that it is mechanically coupled to the crown by means of a chain, the lower end of a telescopic shock absorber being fixed to the swingarm, the vertical profile of the frame having an open upper prolongation of height adjustable insertion and can be locked by means of quick clamps on the seatpost, incorporating the bicycle a few brakes acting on, at least, one of its wheels; characterized in that it comprises a handlebar that engages the upper part of the front fork and is constituted by a substantially vertical section, which in turn comprises at least two telescopic extensible elements, which can be locked by means of quick clamps, and a horizontal upper section central and transverse that incorporates two extreme handlebars and, at least, one handle for braking; the seatpost comprises at least two telescopic elements that can be locked in extension by means of quick clamps; the upper profile of the frame has a rear extension that constitutes a top anchor for the telescopic shock absorber.
