Abstract: The present invention relates to a bicycle lock comprising a lock body and set of arms. The lock body is mountable on the seat of the bicycle. The arms extend from the lock body and terminate in locking surfaces. The locking surfaces are secured together by a locking element. The lock body and arms comprise an integrated textile fabric and steel cable structure simultaneously resistant to common sawing and slicing attacks. The lock body secures the bicycle seat while the arms are threaded through and around bicycle components to attach to a stationary object.
