Seatylock Addresses Confusion Over Bike Chain Locks Amid Fall Campus Theft Warnings

Dover, Delaware – September 16, 2026 – PRESSADVANTAGE –

As United States universities enter the fall term, campus police departments are issuing renewed warnings about bicycle, e-bike, and e-scooter theft, prompting Seatylock, a certified mobility security brand, to clarify a common misconception about how riders evaluate chain locks.

Recent campus reports illustrate the scale of the concern. On September 3, 2026, the University of Wisconsin Madison Police Department reported three electric bicycle and scooter thefts between August 27 and September 2, noting that the return of students typically coincides with increased theft activity. The University of Pennsylvania’s September 8 crime report recorded a secured bicycle, two secured e-bikes, and a secured electric scooter stolen from bike racks during August 24 through 30. California State University Northridge similarly logged multiple secured bicycle and e-bike thefts, including incidents where locks were cut before the bikes were taken.

These warnings often advise riders to upgrade their locks, and some caution that chain and cable locks can be cut quickly. Seatylock notes that campus police are correct to steer riders away from weak locking solutions. The company adds an important technical distinction: the term “chain lock” describes a format, not a security rating. Sold Secure, an independent testing body, maintains certified bicycle chain locks across Silver, Gold, and Diamond grades, meaning construction and certification vary dramatically between products that share the same category name.

Seatylock’s Seatylock Bike Chain Locks Guide separates chain security by certification, reach, application, and construction rather than treating every chain as equivalent. The distinction matters because a lightweight basic chain and a hardened alloy-steel chain designed for higher-security use offer very different resistance to attack, even though both may be marketed simply as chains.

“Riders should not choose a lock purely by its format,” said Michael Shenkerman of Seatylock. “A basic chain, a hardened certified chain, a cable lock, a folding lock, and a U-lock can all behave very differently under attack. The independently verified security level and the real-world locking setup matter far more than the word printed on the packaging.”

The company’s Seatylock Cut-Resistant Chain Lock Guide outlines the factors that determine how difficult a chain is to defeat, including link diameter, steel hardness, and the pick resistance of the lockhead and cylinder. Independent certification, the company explains, verifies these claims and gives riders a standardized reference point that marketing terms such as “heavy duty” cannot provide.

Technique also plays a role. The Seatylock Chain vs U-Lock Security Guide explains that a chain routed tightly through the frame, wheel, and a fixed anchor, with slack minimized and the chain kept off the pavement, reduces the leverage available to an attacker. Longer chains can accommodate oversized e-bike frames, unusual racks, wide posts, cargo bikes, or two-bike configurations that a rigid U-lock cannot reach.

Shenkerman added, “The question consumers should ask is not whether a lock is a chain or a U-lock, but what independently verified security level that specific lock provides.”

Founded in 2008, Seatylock designs, produces, and assembles independently certified bike locks and mobility security products in-house. Its product families include folding locks, U-locks, chain locks, and seat-lock hybrids built around the principle of protection perfected by design.
