As an new avid cyclist, security is of the utmost importance to me, and this bike lock has exceeded all my expectations. From the moment I received the lock, it was clear that this was a high-quality product. The construction feels sturdy and durable, reassuring me that my bike is in safe hands. The locking mechanism is smooth and easy to operate, making securing my bike a hassle-free experience. One of the features I appreciate the most is the generous length of the lock's cable. It allows me to secure my bike to a variety of objects, from bike racks to lampposts, expanding my options when it comes to parking locations. The lock's flexibility, without sacrificing security, is a huge plus. Additionally, the lock's weather resistance is remarkable. I've used it in rain and varying temperatures, and it hasn't shown any signs of deterioration. This longevity is crucial to me, as I rely on this lock to protect my bike for years to come. Overall, I can confidently say that the Bike Lock is worth every penny. Its impeccable security features, durable construction, and user-friendly design make it an excellent investment for any cyclist concerned about bike theft.

    • Just right
Style: 4 Ft. Preset Combo Size: 1 Pack
Remember little Red riding hood and the stuff that was just right? Well this lock isn’t heavy duty nor is it too insecure but is just right. Tough enough to deter thieves and locks what you need. Certainly won’t hold up to even a modest loch cutter, etc but this wasn’t designed for that. Basic lock to deter thieves and it’s perfect for that. Would have liked it to allow for my own combination but no biggie. I can use theirs. Decent basic lock ... show more

This combination bike lock is a solid choice for securing outdoor equipment or bicycles.

    • Good price for the functionality
Style: 4 Ft. Preset Combo Size: 1 Pack
I don’t like how the numbers have to be precisely lined up just for the lock to unlock. So just imagine being out in the rain starts and you’re stuck trying to unlock the lock to get out of the rain or to lock it to get out of the rain. The functionality works decently enough to ensure that the bike is secured and not tampered with. It functions perfectly Other than the lock having to be just correct for it to open properly. I appreciate the fact that the lock came pre-set that way I don’t have to worry about changing and possibly forgetting the combination that I would have created. Of course it comes with the lock code on a small piece of metal that can be attached to a keychain for ease of access or can be hidden away but is also easy to lose. So keeping track of that number is also crucial because I found myself putting in the combination incorrectly where the numbers were different and of course they did not work so I was glad to have kept that little code on me. ... show more

    • I love it!
Style: 4 Ft. Preset Combo Size: 1 Pack
Most locks of this type that I have don't easily go back to its circle shape when not in use but this one does every time which is so nice for so many reasons. The lock seems to be durable and it looks good. Its easy to use and the size/length is big enough to cover most bikes
