ABUS Steel-O-Chain 5805C/75 BK is a combination bicycle chain lock designed for everyday protection of lower-value bicycles in areas with a low risk of theft. Its flexible 75 cm chain allows the bicycle to be secured to racks, railings and other suitable fixed objects, while the resettable numerical code eliminates the need to carry a key.
Key Features
Construction and Design
The lock uses 5 mm square chain links made from specially hardened steel. A textile sleeve surrounds the chain, reducing direct contact between the metal links and the bicycle frame while helping protect painted surfaces against scratches.
The black finish has a neutral appearance suitable for a wide range of bicycles. Its flexible construction allows the chain to be coiled compactly for transport or storage.
Main Functions
The lock opens with a user-defined numerical code, so no key is required. Two-component number reels are designed to keep the digits clearly legible even after extended use.
The 75 cm length provides enough reach to pass around the bicycle frame and a suitable fixed object. Its flexible chain adapts more easily to different frame shapes and attachment points than rigid lock designs.
Use and Compatibility
The ABUS Steel-O-Chain 5805C/75 is suitable for urban, children’s, hybrid and other everyday bicycles. It is recommended for short-term parking in locations where the risk of theft is low.
The combination mechanism is convenient when several people use the same lock, as the selected code can be shared without handing over a physical key. When not in use, the chain can be carried in a backpack, bicycle bag or compatible frame bag.
Additional Features
The lock weighs approximately 500 g, making it practical for regular journeys. Its textile sleeve protects the bicycle frame and reduces noise when the chain touches the bicycle.
This model does not include an alarm function and is intended as a straightforward form of basic bicycle security. Durable number reels and a resettable code support simple everyday use.
Summary
The ABUS Steel-O-Chain 5805C/75 BK is intended for cyclists who need a lightweight, flexible and keyless chain lock. Its 5 mm hardened steel chain, 75 cm length, protective textile sleeve and user-defined combination make it suitable for securing lower-value bicycles in lower-risk locations.
