Title: THEFT-PROTECTION DEVICE FOR BICYCLES
Abstract:
The invention relates to a theft-protection device for bicycles which comprise a frame (2) and a frame-mounted (2) steering column (14) for steering the bicycle. Said theft-protection device is designed to couple the handlebar (6) with a fork (5) for a front wheel (4) in a non-rotational manner. The inventive device comprises a decoupling element for releasing the non-rotational coupling. A coupling element (8) or a connecting element (60) is provided as an decoupling element which subdivides the steering column in two sections (34) and establishes the non-rotational coupling of said steering column sections (34) in a first state and releases it in a second state.
