I like this lock but wish I had ordered a longer one. However, after a year of use the tip has worn off. Consequently I have cut myself a number of times on the sharp edge that is exposed. I will likely go back to the standard lock since this lock is a bit pricey if needing to be replaced every year.
Heavier than I was expecting

Easy to cut. Not worth the price.

do not use this lock alone

I wish I had reviewed this more carefully before purchasing. I love the idea of it, but it is very easy to cut through and should not be used as the only lock. Perhaps it is good for securing your bike while in a location where you can still keep an eye on it but my sons bike was stolen the first the first week of college with just this lock on it. The ottolock website is very clear about the level of security it provides, I just didn't take the time to go there before ordering from The Grommet.

My son-in-law likes that it's lightweight and impenetrable

Lightweight Kevlar Cinch Lock

Secure your ride—and just about anything else—with a lightweight bike lock that merges a cinch tie and a combination lock in one durable and flexible (not to mention compact) design. The Kevlar® fiber and stainless steel band is cut-resistant, and the aluminum lock is smash-proof, making this lock stronger than some others and easier to take along with you, too.


Many cyclists lock up their bikes with a traditional U-lock, but do so begrudgingly—which is how OTTOLOCK was born. This lightweight, tough, and easy-to-use alternative won't weigh you down like a cumbersome U-lock can.

OTTOLOCK comes from pro cyclist Jacob Rathe and co-founder Jake VanderZanden who teamed up to lighten up typical lock bulk without sacrificing security.

It is Made in the USA with a cut-resistant Kevlar® fiber, a stainless steel band, and a smash-proof aluminum combination lock. The adjustable cinching design is more versatile than other locks we’ve seen and works great with gear like a bike, grill, or anything you want to secure. The bendable design coils up into a three-inch diameter when it isn’t on guard duty. more Their Story
