A cable lock stops an opportunist, not someone who came prepared with cutters. This folding bike lock, sometimes called a bike chain lock for its hinged steel-link design, uses steel alloy bars connected by hardened rivets, tested against cutting, drilling, and smashing, then folds down to a compact 7.5 x 6.6 x 5.5cm block that mounts right on the bike frame instead of living in a bag.
The 78cm length wraps around a bike frame, wheel, and a fixed post or rack all at once, giving real anti-theft coverage instead of just locking the frame to the wheel. A dedicated mount attaches to the seat post or frame, so the lock travels with the bike and is ready whenever needed.
Why It Stands Out
- ✓ Hardened steel alloy rivet links (HRC45) — quenched for extra hardness, tested against cutting, drilling, and smashing.
- ✓ Anti-drill lock cylinder — the keyhole is reinforced against drill attacks, a common way basic locks get defeated.
- ✓ 78cm folding length — long enough to secure the frame, a wheel, and a fixed point, not just the frame alone.
- ✓ Folds to 7.5 x 6.6 x 5.5cm — compact enough to mount on the bike instead of taking up backpack space.
- ✓ Two mounting methods — strap it to a seat post with the included skidproof loop straps, or screw the mount directly to the frame.
- ✓ 3 keys included — spares on hand without an extra trip to get one cut.
- ✓ Applicable to MTB, road bikes, motorcycles, and e-bikes — one lock covers most of what's in a garage.
Where to Use It
- → Street parking — locking up a bike, e-bike, or motorcycle at a rack or post.
- → Trailheads — anywhere a flimsy cable lock or basic bike chain lock isn't enough.
- → Daily commuting — compact folded size makes it practical to keep mounted permanently.
How It Works
- Hardened steel bars connect via rivets that resist cutting, drilling, and prying.
- The lock folds flat at each rivet joint, collapsing into a compact block for storage.
- An anti-drill cylinder protects the keyhole itself from being drilled out.

How to Use
- Choose a mounting method: thread the included loop straps through the mount and secure it to the seat post, or screw the mount directly to the bike frame with the included screws.
- Push the folded lock into the mount until it clicks into place for storage.
- To use, unfold the lock, wrap it around the bike frame, wheel, and a fixed rack or post, then insert the key and lock.
- To reset or remove the lock core, take the key out, the core pops out, then press it down to reset.
Tip: Keep one spare key at home in case the daily-carry key is lost.
Care and Maintenance
- ✓ Wipe down the lock and keyhole periodically to keep dirt and grit out of the mechanism.
- ✓ Keep spare keys somewhere safe and separate from the ones carried daily.
- ✓ Store the lock folded in its mount when not in use.
