Abstract
Abstract A drop-type bicycle handle is provided with hand operating brake means having a conventional brake lever member pivoted to a bracket secured upon the handle. Said lever member has a stepped portion formed at a portion thereof which abuts against the bracket and an engaging member is pivotably secured to the lever member for releasable engagement with the stepped portion. Upon release of this engaging member from the stepped portion, the lever member is rotated further so as to further release the release wire.
