Widder 47" Folding Bike Lock — 47-inch Hardened Steel Link with AirTag Chamber, Mount & 4 Keys

Widder’s 47-inch Jupiter folding lock is a heavy-duty, portable bike lock that combines a long, hardened steel link chain with an integrated bracket and an AirTag-sized tracker chamber for added recovery options.

Built to secure bicycles, e‑bikes, scooters and multiple-two‑wheeled setups, this folding lock balances robust cut resistance with convenient transport. The lock’s broad, flat folding links resist common theft tools while remaining compact when stowed in the included bracket. With a 47" reach, four keys and a discreet tracker compartment, it’s designed for riders who want more coverage and practical anti‑theft features without carrying an oversized chain.

How does this lock protect against common theft attempts?

The Widder Jupiter uses a special hardened-steel core inside each wide folding link to increase resistance to bolt cutters, saws and prying tools. Its construction focuses on real-world force and cutting resistance rather than only marketing claims.

• 1" x 0.3" wide fold links with a reinforced steel core for improved cut resistance.
• Flat, articulated links reduce leverage points for crowbars and angle tools.
• Lock cylinder and housing designed to resist tampering and forced entry.

Will the 47" length work for different vehicles and locking situations?

Yes — at 47 inches the lock wraps around larger fixed objects and can secure two bikes or an e‑bike plus a post. The extended length allows for flexible routing so you can lock frames and wheels together or loop around wider anchors.

• Long reach to secure bikes, scooters, e‑bikes, and multiple bicycles at once.
• Wraps around trees, poles and larger fixtures that shorter locks can’t reach.
• Folds compactly for transport while offering extended span when deployed.

How easy is it to carry and mount on my bike every day?

The lock ships with a mount and Velcro frame straps so you can fasten it to bottle‑cage holes or frame tubing for daily riding. The bracket is slim and flexible to keep the lock stable and out of the way while riding.

• Included mounting bracket with hardware for bottle cage mounting points.
• Non‑slip Velcro frame binders for alternate attachment without drilling.
• Compact folded profile that minimizes bulk while stored on the bike.

What extra features help with recovery if my bike is stolen?

The back of the bracket includes a dedicated chamber sized for AirTag and similar trackers, letting you add a small tracking device for locating a missing bike. The lock also includes four keys so multiple users can access the lock when needed.

• Tracker chamber fits Apple AirTag and comparable chips (1.25" diameter, 0.3" depth).
• Four physical keys included for family or shared use and backups.
• Bracket design shields the tracker and keeps it hidden from plain view.

Who is this for? Riders who want higher-than-average resistance without hauling a heavy chain will appreciate the Widder 47" Jupiter folding lock. It’s a strong option for commuters, apartment dwellers and parents sharing bikes who need a long reach, reliable mounting, and a built‑in tracker option. If you prioritize a balance of portability, length and cut resistance — plus the convenience of multiple keys and a dedicated tracker cavity — this foldable lock is designed to meet those needs.
