Otto Bike Locks - RA Cycles

Cerraduras para bicicletas Otto

OTTOLOCK Cinch Locks solve a problem every cyclist knows — the gap between a quick stop and full lock-up. Too heavy to carry two locks, too risky to leave a bike unsecured for even ten minutes. OTTOLOCK's solution is a flexible, stainless steel-reinforced cinch lock that wraps around your frame and a fixed object in seconds, compact enough to fit in a jersey pocket and light enough to forget you're carrying it.

RA Cycles carries the full OTTOLOCK lineup: standard Cinch Locks in 18", 30", and 60" lengths, plus the Hexband variants with extra-layered protection for higher-risk environments. Each is an everyday carry lock designed for quick stops — coffee shops, trailheads, quick errands — where a full U-lock would stay home.

About OTTOLOCK

OTTO DesignWorks is based in Portland, Oregon, founded in 2016 by lifelong cyclists who wanted a compact lock worth actually carrying. The original Cinch Lock launched after a successful crowdfunding campaign — a patented design combining stainless steel with OTTOLOCK's signature layered construction, hand-made in Oregon with components sourced across the United States. Since launching, OTTOLOCK has sold over 300,000 cinch locks worldwide and earned recognition from Bicycling Magazine and Popular Mechanics. Learn more at OTTOLOCK's official website.

At RA Cycles, the OTTOLOCK collection covers standard Cinch Locks and the more cut-resistant Hexband models — available in 18", 30", and 60" lengths to match your typical stop duration and carry preference. The 18" is a jersey pocket staple for quick café stops; the 60" gives you enough reach to loop through a wheel. All versions are light enough to carry every ride without thinking about it.

That half-century belongs as much to you as it does to us. The riders who kept coming back, who sent their friends, who trusted us with bikes that matter — you're the reason we're still here.
