Muy bueno, para andar en la bici todos los días
Tengo el NY LS y ese lo uso solo cuando dejo la bici por periodos largos ya que es muy pesado pero muy difícil de abrir para amantes de lo ajeno. El mini es genial para todos los días, pesa approx 1kg pero no se siente en la mochila, la extension tiene una curva de aprendizaje, pero mi mejor tip es trata de buscar como asegurar el cuadro primero y luego metes el extensor a la llanta. Muy recomendable

Excellent lock!
Well worth the money. It is light weight and easy to carry while biking. I’m able to securely lock my bike while not in use and don’t have to worry about it getting stolen while running my errands.

Ok, but awkward & not worth $100+ paid for it.
So far has worked okay to lock up my electric scooter, however:1.) I wish it came with a bracket of some kind so that it could be stored somewhere on the scooter while I am driving it, rather than always having to fit it into my bag. The lock is heavy & awkward.2.) The whole reason I purchased this particular lock was the innovative, (detachable) smaller “u” part that’s included- only to find out the additional part does not have the same protection garuntee as the rest of the regular U-lock, which is kinda bizarre & defeats the purpose.3.) Lastly, tried to register my keys online as suggested, but the process is klunky & requires one to select the category/make/model name of the lock that your keys work with first- & my lock was not one of the choices- so I could not & have not successfully registered my keys.

Solid – and lasts!
Great item – had one for 10 years and still going, bought a second for a child going off to college! B-)

Solid lock
Exactly what I expected

awesome, would buy another
Very useful, great size, much preferred to carry over the NYC Kryptonite heavy duty lock. Seems quite durable but no one has appeared to try and saw it/steal my bike yet. A bit of a learning curve to properly and quickly hook wheel, frame, and bike rack.

Zuverlässiges Bügelschloss
Verrichtet seht mehreren Jahren zuverlässig seinen Dienst. Besonders praktisch ist dabei der zusätzliche Bügel. Um eine Laterne passt es leider nicht und insgesamt wäre es ein bisschen größer besser, aber das wird natürlich dann mit einem höheren Gewicht erkauft.

Love it! Very versatile!
Solid construction, will deter casual theft looking for easy score. Nothing is 100% safe so I also use a second, larger Kryptonite to secure back tire to bike frame along with the rack in heavy urban areas.With smaller loop can secure quick release front tire or back tire as situation demands. Also loop perfect size to lock electric scooter to bicycle while securing everything to bike rack.

Works really well with Segway scooter, wheel and frame.
I’ve only used it for a week, I like how it can be attached through the wheel and the frame like my pic. Not as easy as a cable or chain lock but my scooter was stolen with a cheap segway cable lock that was cut in a busy public train station. Airtag helped me get it back.

7/10 security so suited for short stays in public areas. Can secure wheel and frame in one lock.
This is a messenger/ mini+ with an additional shackle. It weighs 1.12kg, and comes with two keys each with a wrist strap, I bought this as an additional lock for the front wheel on my Brompton, the rear being secured with a New York Kryptonite, passing through the frame and wheel. This particular lock has a security rating of 7/10, which is OK for relatively safe areas, combined with the heavy duty New Yorker through the rear wheel and frame, it should be the last choice of a cycle thief (as long as the secured post is strong enough). Good value for a mid security lock, quite light in weight. Register the key number with Kryptonite for free, so you can get a replacement free, and consider registering the lock too so you can get up to £1.5k back if the bike gets stolen, latter costa about $50 for 2 years.

Good lock
Great lock for good price. A bit finicky with the extra lock loop. But you can choose when to use it or not since it is detachable
