## Long description

Folding steel lock rock machine F.Lock 20.85 in black and grey provides compact, portable security for bicycles and similar equipment. The 850 mm total length when unfolded and robust steel construction are designed to secure a bike frame to fixed objects while remaining convenient to carry and mount to the frame. The set includes two keys, one fitted with an LED to aid key insertion in low-light conditions, and the lock weighs 860 g.
Advantages
Steel construction gives strong resistance to cutting and tampering while the folding design keeps the lock compact for transport and frame mounting. The 850 mm length offers flexibility to lock around larger frames or fixed structures. Two supplied keys improve convenience and sharing, and the LED-equipped key simplifies operation in dim environments. The black and grey finish provides a neutral appearance that suits most bicycle styles.

Securing city, commuter and hybrid bicycles
