Abstract
A multistage freewheel for bicycles, comprising a plurality of at least two sprockets which are divided into at least a low speed stage and a high speed stage which are rotatable independently with respect to a support. Each of the sprockets is separately applied with a rotary resistance so that a single sprocket may be of less resistance thereby securing safety in the operation of the bicycle.
