Waterproof Combination Chain Lock for Bicycle Blue 100 cm

Combination anti-theft chain for bike, length 100 cm, thickness 4.5 mm, blue colour, weight 350 g. This model is a bicycle anti-theft chain designed for everyday use, with a covered structure and a flexible format suitable for securing the bike to a fixed point. The 100 cm length allows the chain to be passed around the frame, a wheel or a support depending on the usage configuration. The blue colour makes it easy to quickly identify the lock among bicycle accessories.

Intended for urban cyclists, users of city bikes, leisure bikes, folding bikes or other two-wheelers requiring simple security, this combination lock is suitable for short-term parking or as a supplementary solution with another locking system. Its design with a cover partly protects the frame against direct rubbing from the chain during use.

General description
This bike security chain combines a metal chain body with a keyless code locking system. The outer fabric covering helps limit direct contact between the links and the bike’s paintwork. The structure is designed for practical everyday use, particularly for securing a bike to a stand, barrier or suitable support. The water-resistant and rust-resistant claim indicates a design aimed at better resistance to normal conditions of use, subject to normal maintenance.

The textile sleeve helps reduce marks caused by repeated contact with the bike structure.

Its weight of 350 g remains suitable for carrying in a basket, a bag or around the frame depending on the user’s habits.

To extend its service life, it is recommended to avoid prolonged contact with mud or standing moisture, then dry the lock if necessary after exposure to rain. Even if the design is stated to be water-resistant and rust-resistant, regular maintenance remains useful to keep the mechanism operating smoothly.
