Kryptonite Evolution 11-14mm U-Lock with FlexFrame-U Bracket

It fits in a back pant's pocket which was the selling point for me. Perfect for quick trips around town when not wanting to carry a lot of things or weight. The shackle size is a limiting factor, so it may not work well in all instances, but I use it on street signs. I bought it for that specific use, so I'm happy. A lamp post or large diameter bike rack may prove problematic, but it would also work well as a second lock to only lock a wheel to the bike frame in case your biking grounds have wheel thieves. Being lightweight and compact makes it a great supplemental lock if you like to use multiple locks.

Love how it comes with a mount for the u lock that attaches to the bikes frame. Reasonable price considering peace of mind. I’m capable of locking both the rear tire and frame to the bike rack. Would have loved if it came with something to tie the front tire as well but this works for my commute to the gym.

Muy robusto y resistente, más práctico para el uso diario que el tamaño estándar. Solo no permite enganchar la llanta trasera y el marco. El soporte es fácil de instalar y queda perfecto.

Had one before

Got new bike recently and after long research I decided to go for Evolution mini 5. Lock is very sturdy and also practical and small. Didn’t wanted to buy bigger ones as I like to have on the bike smallest amount of add-ons as possible to keep it light. Yes, you cannot lock the bike on every post possible but you always have around some good fence or something so there is no problem on being “too small”. It is very easy to lock and unlock. Also, lock holder is great, no movements, no noises or anything. You pay one time 50€ for a good lock and you are good to go for a long long time, also most of the bikes stolen are ones with cheap chains. Good luck in cutting this xD
