B62LBRAKES SPECIALLY ADAPTED FOR CYCLES arrangements in cycles for adjusting wheel-braking force to meet varying vehicular or ground-surface conditions B60T8/00This subclass covers only adaptations of brakes and their actuating mechanisms peculiar to their use on cycles.This subclass does not cover brakes or actuating mechanisms of wider applicability, which are regarded as of general type, irrespective of whether described or claimed only for cycles, which are covered by subclass B60T or the relevant subclass of F16.In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
