  • Patent number: 10501137
    Abstract: The present invention provides a handlebar lock system which (i) can be used for a moving body whose traveling direction is changed with a handlebar and (ii) includes a handlebar locking device which makes it difficult to unlock the handlebar by a forcible method such as breaking. The handlebar lock system includes: a handlebar locking device (20); and a user interface (8) which notifies a user of an operation state of the handlebar locking device (20), which operation state includes at least a lock state of the handlebar (5). The handlebar locking device (20) is provided in a frame of a bicycle so as to be not viewable from outside of the bicycle. The control section (100) identifies the operation state, and then outputs, via a communication section (101), information indicative of the operation state thus identified. A control section (8a) of the user interface (8) receives, from the handlebar locking device (20), the information indicative of the operation state.
