I’m really impressed with this lock. The 5-digit combination feels secure and easy to set, and I love not having to carry a key around. The cable is thick, flexible, and long enough to wrap around both my bike frame and wheel, giving me peace of mind when parking in public. The build quality feels sturdy and reliable, not flimsy like cheaper options. It also works great for my scooter and gate, which adds extra value. The numbers turn smoothly even in cold weather, and the protective coating keeps it from scratching paint. For the price, it’s a fantastic buy, solid, convenient, and dependable. I would absolutely recommend it to anyone looking for an affordable and secure bike lock.

I got this lock to secure my electric scooter and a wonder fold wagon. The length of the lock was decent and it was easy to install. I was able to double wrap the lock thru the wheel of the scooter and also through the lower bar with ease. It looks and feel to be very sturdy and solid with a 5 digit combination code that's easy to change whenever you feel the need to. It also came with a lock holder that can be bolted down and attached to whatever part of item that is being secured. I attached mine to my electric scooter handle bar and store the lock with my scooter so that it will always be with me when I'm using the scooter. It worked well to secure two of my expensive items and the price of this lock was very reasonable.

I’m really impressed with this bike lock. The 5-digit resettable combination gives me extra peace of mind compared to standard 4-digit locks, and it feels much more secure. The cable is thick, durable, and flexible, making it easy to wrap around my bike frame, wheels, or even my scooter. Setting and resetting the combination was simple, and the mounting bracket is a big plus—it attaches firmly to the bike so I can carry the lock without taking up space in my backpack. The lock mechanism feels solid and smooth, and the length of the cable is perfect for locking up in different places. Overall, this is a reliable, sturdy, and convenient anti-theft lock that offers great value for the price. Highly recommended for anyone who wants stronger security for their bike or scooter!

I found this lock very practical and easy to use. The cable is thick, flexible, and has a transparent cover that makes it look sturdy and durable. The combination lock works well: the numbers turn smoothly, and the mechanism feels secure when closed. What I like most is that it doesn't need a key, so there's no risk of losing it. It's ideal for securing a bicycle, an electric skateboard, a scooter, or even a suitcase. It also comes with a mount for attaching it to a bicycle, which makes it easy to take it with you wherever you go.
