Kryptonite Evolution Lock U- Bicycle

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

Really love this lock. It’s literally small enough for travel but most importantly to hook your bike to any bar/post. This has lasted me a couple months and I’ve had no problems with it. Heard many reviews saying that it rusts easily but I havnt experienced that even though my bike has been out every day even when it’s raining. The build of the lock is strong and durable. It’s theif protective as it would take time for someone to cut through it, so it would really put them off in a public setting. A percent of this product is that because it’s heavy, they have supplied a lock holder to not weigh you down. Would 100% Recommend to a friend.

I think it's worth paying the price premium for Kryptonite since it the safety deterrent on bike thieves

This is a good solid lock in a portable size though a little heavy. I’m very happy with it apart from the poorly finished aluminium mounting bracket - the sharp edges put a scratch on my new bike. I have since removed the bracket (easy to do) and just carry the lock in a bag instead of using the supplied bike mount.

Good build, not too bulky.

I bought this as an additional lock for my bike to lock my front wheel to the frame. It's quite small so will fit snugly around your wheels and a stationery object. I would say that for some bike stands it might be a little small to get around the post and the wheel but it is still a good buy. It's also more portable to take in your bag than other locks. Sadly I could not fix it to my frame due to the geometry of my bike.

I bought this lock a few months ago and the lock has seized up. My previous kryptonite lock lasted over 10years before this happened so not quite sure why this one has crumbled so quickly.

Disappointed with the lock. Not as good as the original short orange D locks. The “lock” part, sometimes the key just keeps spinning so this can be a bit faffy when trying to lock your bike up
