Seatylock Launches Bike Chain Locks Guide for Smarter Urban Security

Dover, Delaware – August 25, 2026 – PRESSADVANTAGE –

Seatylock, the design-led mobility security brand, has expanded its rider-education resources with a comprehensive new knowledge hub focused on bike chain locks. The resource is designed to help cyclists move beyond generic “heavy-duty” marketing claims and understand the measurable factors that actually determine chain-lock security.

The launch responds to a growing challenge for everyday riders. As higher-value bicycles and electric bikes become more common in cities, selecting an appropriate lock has become increasingly complex. The new Seatylock Bike Chain Locks Guide explains how riders can evaluate chain locks using concrete criteria such as link thickness, hardened-steel construction, independent security certifications, chain length, weight, locking technique, anchor choice and parking risk.

Rather than relying on marketing language, the hub encourages an evidence-led approach. It explains that link diameter directly influences how much force is required to defeat a chain, that hardened alloy steel can dull cutting tools before a cut is complete, and that the lockhead and cylinder can represent weak points if poorly engineered. The guide also addresses the rising prevalence of angle grinders in bike theft, a factor that has changed how riders should assess real-world protection.

A central theme of the resource is that owning a lock does not by itself guarantee security. The Seatylock Heavy-Duty Bike Chain Lock Guide combines product-selection advice with correct locking technique, including securing the frame and rear wheel to a fixed anchor while minimizing chain slack. The hub notes that flexibility is one of a chain lock’s distinct advantages, allowing it to wrap around larger or irregular anchors that rigid locks may not reach.

Michael Shenkerman, speaking for Seatylock, said the hub was created to close a persistent knowledge gap. “Many riders assume the word heavy-duty tells them everything they need to know, when in reality security depends on measurable elements like link diameter, steel hardness and independent certification,” he said. “The aim is to give cyclists a clear framework so they can match their protection to how and where they actually park.”

The resource dedicates particular attention to electric bikes, which typically carry higher replacement values than standard bicycles. The Seatylock E-Bike Chain Lock Security Guide explains how link thickness, usable chain length and certification level should scale with a bike’s value, and outlines when a two-lock strategy may be appropriate for high-risk environments.

“Electric bikes change the calculation,” Shenkerman added. “A higher-value bike often warrants a certified chain as the primary lock, sometimes paired with a second lock, and enough usable length to reach oversized frames and motor housings.”

The hub aligns product guidance with independent certification benchmarks, including those administered by recognized institutes that use standardized, time-limited attack testing to assess theft resistance.

Founded in 2008, Seatylock designs, produces and assembles bike security products in-house, including cylinders and keys. The brand holds independent certifications and international patents, and its product family spans folding locks, U-locks, chain locks, seat-lock hybrids, detachable seats and accessory protection systems built around its philosophy of Protection Perfected by Design.
