  • Good enough protection where I live
Size: 4 Foot Cable/12mm Shackle
I live in an area where bike theft is not very common, but I am sure if I left my bike sitting outside unlocked someone could take it. I got this bike lock because of the steel shackle and Kryptonite has a good name in locks. In other places I have lived I have had cable locks cut and my bikes stolen so I decided the U lock would at least take some time for someone to cut. They would also probably make some noise and alert people in my area. This bike lock is more their budget big box store brand. Think "Hey we want to sell these in Wal-Mart so lets make it a reasonable price" It's better than master lock, but can still be compromised with a skilled lock picker. If you live in a place where theft is high don't get this one. If you live in a place where crime rates are low and you will be locking your bike up for like an hour or so this should do well. In fact this would be a perfect lock for a kids bicycle at school. This will do well for most situations but if you have a nice bike in a busy city maybe opt for something with a bit more protection. ... show more

  • Compact and easy to carry, Weather Resistance.
Size: 4 Foot Cable/12mm Shackle
This lock offers strong resistance against cutting, leverage attacks, and other theft attempts. It feels solid and durable, giving me peace of mind when leaving my bike unattended. The dual-layer protection of the U-lock and cable provides versatility for locking my bike in different configurations. The compact size of the U-lock makes it easy to carry, and the cable can be coiled up neatly. However, some users might find it slightly bulky for small bike frames. • High-security U-lock with a durable braided cable. • Compact and easy to carry. • Versatile for securing both bike frames and additional parts. • Affordable price for the level of security it offers. The Kryptonite Bike U-Lock with Braided Steel Cable is a solid investment for cyclists looking for reliable protection against theft. Its combination of a strong U-lock and flexible cable offers good security and versatility, making it suitable for most environments. While it may not be the most heavy-duty option on the market, it strikes an excellent balance between security, portability, and price. For casual riders or those locking up in moderate-risk areas, this lock is highly recommended. ... show more

  • Very good quality. A few bad design features tho if h
Size: 4 Foot Cable/12mm Shackle
Extremely high quality—what I’d expect from a high end bike store. The ulock is a bit small to close while locked on both my frame, a bike rack, and my wheel though, despite being the recommended way to lock in the how-to guide. Also, I always find having a physical key hard though, so I wish I got a combination lock. The cord is nice and more secure, but I have a hard time attaching on my bike when riding without a bike bag. I have to wrap it around my bike frame multiple times and done like how the u lock rocks when I ride and gets in the way. Otherwise, very good product and would say it’s above the market quality!!! ... show more

  • Stronger than the metal rack I was locked to
Size: 4 Foot Cable/12mm Shackle
My bike still got stolen but leaving 5 stars because the thieves had to break through the rack instead of the lock to take my bike 🙃. So back here to buy my second one.

  • Bang for ur buck!
Size: 4 Foot Cable/12mm Shackle
This model is the best bang for your buck! It's small, lightweight and comes with cable to ensure you can at least wrap around your bike and the wheels. I wanted to get. Kryptonite but it's like with so many models...it felt like either the lock was little value or really expensive. This lock is very affordable but still maintain all the features of more expensive lock model. It's ranked 7/10 which is pretty good without the higher lock price. ... show more

¡Wow! Es un condado rígido y muy funcional para asegurar mi bicicleta. Se nota su seguridad con manipularlo. Recomiendo la marca y a Amazon como plataforma. Muy puntuales, llegan antes de tiempo. Me siento feliz con su logística de entregas.

  • No Bueno
Size: 4 Foot Cable/12mm Shackle
This is pretty lame with its short 8mm cable and the lock is sloppy. Clumsy to use! Going back to the Intekin at the same price with a substantial 6’ cable!
