Bonin Foldable Lock 840 mm – with Frame Mount, 16 mm, Black
Bonin foldable lock 840 mm — compact, secure, and always mounted on your frame, ready for every urban stop.
Security without compromise, zero space needed.
The Bonin foldable lock 840 mm is the smart solution for riders who want an anti-theft lock always at hand — without carrying it in a bag or forgetting it at home. When closed, it measures just 188 x 54 mm — smaller than a water bottle. When unfolded, its 840 mm length lets you secure your frame and wheel to poles, racks or standard bike stands.
Simple, stable mounting:
The included frame bracket attaches directly to your frame with screws (included) and holds the lock firmly in place — no dangling, no rattling while riding.
Why choose this Bonin lock?
- Compact folded design — takes up minimal space, fits discreetly under the saddle or on the frame
- 840 mm open length — enough to lock your bike to common urban fixtures
- Frame mount included — no need for bags or straps
- Robust build — hardened steel bars with anti-scratch coating
