Master Lock Folding Bike Lock with Key, Lock with Key 2-3/4 feet, Hardened Steel Links & Vinyl Cover

The Master Lock 8335EC is a heavy-duty folding bike lock made from hardened steel links that delivers compact, cut- and pry-resistant security for bicycles and scooters.

Compact when folded and rigid when deployed, this 2-3/4 ft (84 cm) folding lock balances portability with strong physical resistance. Its 3.5 mm hardened steel link construction and stainless-steel rivets reduce vulnerability to cutting and prying, while a vinyl cover protects bike finish and improves weather resistance. A simple Velcro-mounted carrier keeps the lock on your frame or rack so it’s always within reach.

How does this lock protect against cutting and prying?

The lock uses multiple hardened steel links joined with stainless-steel rivets to make cutting, sawing, and levering more difficult than single-plate designs. Its compact folding geometry also reduces exposed leverage points, discouraging opportunistic thieves.

• 3.5 mm hardened steel links for material strength
• Stainless-steel rivets at each joint to resist prying
• Folding design minimizes accessible leverage areas

Will this scratch or damage my bike’s paintwork?

No — the lock is sheathed in a protective vinyl cover designed to minimize abrasions and shield components from rain and grit. The vinyl also reduces noise when the lock rests against the frame during rides.

• Vinyl-covered body cushions contact with frame
• Sealed rivets and links help limit dirt buildup
• Weather-resistant finish lowers corrosion risk

How practical is the lock for daily use and transport?

The 84 cm length secures most frames to fixed objects while folding down to a compact shape for storage. The included Velcro carrier bracket installs on tubes or racks for quick access and neat transport between trips.

• 2-3/4 ft (84 cm) unfolded reach for anchoring
• Velcro-mounted carrier bracket for frame or rack attachment
• Folds compactly to reduce bulk in transit

What’s included and what kind of warranty does it have?

The package arrives with the Master Lock 8335EC folding lock, key mechanism, and a Velcro-styled carrier bracket for on-bike storage. Master Lock backs the product with a Limited Lifetime Warranty offering long-term support from a recognized security brand.

• Lock with keyed cylinder for reliable closure

Who is this for? Urban cyclists, e-scooter riders, and commuters who want a compact lock that balances portability with robust physical resistance will find the Master Lock 8335EC suitable. It fits riders who need a practical onboard storage solution and prefer a keyed lock over combination systems. While not a substitute for heavy chain locks in extremely high-risk areas, this folding lock is ideal for everyday stops at cafes, transit hubs, and workplace racks where convenience and solid deterrence matter.
