Seatylock Security Collection

Lock the bike. Lock the parts. Ride stress-free.

Outsmart grab-and-go theft with Seatylock’s proven hardware—built to secure both your frame and the easy-to-steal bits. This collection pairs a Sold Secure Silver–rated Foldylock for primary bike security with X-LOCK components that replace vulnerable quick-releases and standard fasteners.

What’s in the collection

  • Foldylock Classic (Silver rated) – Compact, quiet-folding link lock for daily parking; rugged, drill/bolt-cutter resistant plates with a rubberized, frame-friendly finish.

  • X-LOCK Axle Bolts – Anti-theft wheel skewers that replace quick-releases; open with the included coded tool socket—keeps wheels on your bike, not in a thief’s backpack.

  • X-LOCK Seatpost Clamp – Tamper-resistant clamp to protect your saddle/seatpost. Multi-size shim kit covers common seat-tube diameters (28.6 / 30.0 / 31.8 / 35.0 mm).

  • X-LOCK Axle Nuts (3/8" x 26 TPI) – Security nuts for hub-axle bikes that use this thread; install with the matching coded tool socket.

Why riders choose Seatylock

  • Layered security: Frame + wheels + saddle protection in one system.

  • Everyday tough: Weather-resistant materials and low-noise design.

  • Fast setup: Most installs take 5–10 minutes with basic tools.

  • Clean look: Low-profile hardware that doesn’t scream “add-on.”

Tip: Start with the Foldylock Classic for your primary lock, then add X-LOCK wheel and seat protection to eliminate common “parts theft” losses. Check thread/diameter specs on your bike (e.g., 3/8" x 26 TPI axles; seat-tube size) before ordering.
