Description

Serious security for serious cyclists. The EcoBike Premium Chain Bike Lock delivers heavy duty theft protection with a 5mm thick hardened steel chain, 420D nylon protective sleeve and a precision press-to-lock cylinder mechanism — backed by 2 keys for confident, reliable security on every ride across Australia.

5mm Thick Chain — Thicker Than the Competition

The chain on the EcoBike Premium Chain Bike Lock measures approximately 5.16–5.19mm in diameter — noticeably thicker than standard chain bike locks in Australia. A thicker chain means greater resistance to bolt cutters, hacksaws and angle grinder attacks. If you are comparing bike chain locks in Australia and want genuine theft resistance rather than a false sense of security, the 5mm chain is the specification to look for. One of the most heavy duty bike locks in Australia at this price point.

420D Nylon Protective Sleeve — Zero Scratches on Your Frame

The entire chain is wrapped in a military-grade 420D nylon sleeve — the same material used in high-end cycle gear. The 420D nylon completely prevents the steel chain from scratching or marking your bike frame, fork or wheel rims when locking up. It also provides an additional layer of visual deterrence and cut resistance. The sleeve can be wrapped around your seat tube or frame for secure, rattle-free carry while riding — no bag needed.

Press-to-Lock Cylinder — Fast, Secure and Tool-Free

The EcoBike premium chain lock uses a unique press-to-lock cylinder mechanism — simply press the shackle pin into the lock cylinder and it locks instantly with a firm click. No fumbling, no twisting, no delay. Unlock with either of the 2 included keys. The precision cylinder lock mechanism is harder to pick than standard barrel key locks and provides a clean, positive locking action every single time.

Easy to Carry — Wraps Around Seat Tube or Frame

Unlike bulky U-locks or heavy chain locks that require a bag or basket, the EcoBike chain bike lock wraps neatly around your seat tube or top tube when not in use — secured with a simple wrap and the lock itself. The 420D nylon sleeve grips the frame without slipping and the chain stays quiet and rattle-free while you ride. Lightweight enough to carry on every ride without noticing it is there.
