A bicycle tire comprises a toothset (5) of substantially radial generatrix (G), positioned to collaborate with a complementary toothset of a driving pinion of an electrical assistance device. The toothset (5) has teeth (51) that are equidistant by a pitch p, each tooth having a length l, in the direction of the generatrix (G), and a substantially triangular section, in a plane perpendicular to the generatrix (G), of height h. Each tooth (51) comprises an elastomeric material having an elastic shear modulus G* at least equal to a threshold elastic shear modulus G*s, G*s being such that the displacement d of the crest of each tooth is equal to 0.2 times the height h of the tooth under the action of a uniform pressure, applied by the complementary toothset to the side that forms the smallest angle, equal to 650/(l×h×(2.67−0.33×p)). |
