BICYCLE AIR TYRE

摘要

Bicycle tire comprising continuous toothing (5) cooperating with complementary toothing of a drive pinion of an electric assist device. The toothing has a substantially radial generatrix (G) with respect to the rotation axis of the tire in the axial direction (YY′). Toothing (5) is positioned circumferentially on an axially outer face (31) of at least one sidewall (3) and comprises teeth (51) having height h and length l, and comprising an elastomeric material having a Shore A hardness. The height h of teeth (51) is at least equal to 0.6 mm and at most equal to 3 mm. The length l of teeth (51) is at least equal to 0.15 times and at most equal to 0.50 times the section width S of the tire. The elastomeric material of teeth (51) has a Shore A hardness of at least equal to 55 and at most equal to 85.
