How they are built
Collapsible Steel Plates
The folding design uses hardened steel plates that resist cutting. This provides the security of a U-lock with more flexibility.
Keyed Entry Reliability
These models use traditional keyed cylinders. This ensures a secure physical connection for high-value bicycles.
Size Variations
The FS480 offers a long 1300 mm reach for large objects. The FS 280 Two.GO provides a more compact 80 cm length.
Professional Black Finish
All models feature a clean black aesthetic. The materials are chosen for long-term durability in urban environments.

Buyer notes
