Hardened Steel Security for Compact Frames
A matte black silhouette that folds into a compact form, this ETOOK security lock is built for the rider who values both protection and portability. The plastic coating ensures the metal stays clean against your bike's finish.
Engineered from heat-treated special hardened steel, it withstands hydraulic cutters, sawing and drilling. It suits cyclists seeking robust security without the bulk of a traditional U-lock.

MATERIALS
Special Hardened Steel Construction
The core of the lock is forged from heat-treated special hardened steel, a material chosen for its ability to withstand significant force. This density allows the bars to resist 9T hydraulic cutters, as well as brute-force attacks like thumping, sawing or drilling. The result is a barrier that feels substantial in the hand, promising durability through daily use.
DESIGN
Protective Coating and Slim Key
To prevent scratches on delicate paintwork, the 4mm thick bars are finished with a protective plastic coating. Inside, advanced cylinder technology employs a key of only 0.3-0.6mm thickness, a design choice that complicates technical picking attempts. An anti-drilling cap further shields the lock cylinder, adding another layer of defence against common theft methods.
FUNCTION
Forward Removal for Small Frames
Recognising that not all bicycles offer ample space, the lock mechanism is designed to be removed forwards. This specific orientation makes it particularly suitable for small-framed bikes where rear access might be restricted by fenders or gears. The folding nature of the 750mm assembly allows it to collapse into a manageable shape for storage.
DETAILS
Robust Rivets and Packaging
The bars are linked by hardened steel rivets capable of bearing 1.5 tons of pulling capacity, ensuring structural integrity under stress. The product itself weighs 720g, providing a balance between security mass and carry weight. It arrives in a compact 10 x 10 x 10 cm carton weighing 0.5 kg, ready for immediate installation.
