Metal drive roller (1) for a light vehicle provided with a bicycle wheel, such as a bicycle or a wheelchair, having a frustoconical usable outer load-bearing surface (31, 32), the usable outer load-bearing surface (31, 32) having a plurality of indenting elements (4) having a radial height (hr) of between 0.5 mm and 5 mm, a mean circumferential length lc, a maximum axial width lam, and ending with a sharp point, the indenting elements (4) covering at least 80% of the usable outer load-bearing surface (31, 32). The projections of the sharp points of the indenting elements (4) perpendicular to the axis of rotation (2) onto the axis of rotation (2) are substantially equally distributed.
