Lucchetto formidabile che quando non chiude la bici funge da sellino.Non c'è verso di romperlo. Potrà riportare segni superficiali di tentativi di scasso ma rimarranno solo tentativi

Really nice materials, comfortable, comes with replacement keys in case you lose your key and different colors for you to choose from. I would buy it again without question!

It really is both seat and folding lock. The only problem I had was the adapter (which holds it on the bike) worked loose. Now I carry my Allen keys with me when I ride. I understand that some people pay more just for a folding lock.

My son had a cable lock on his Ebike. His Ebike was stolen in just a few minutes. I have had zero problems with anyone messing with my Ebike. In order for someone to be able to cut through the seat bar they would need a cordless grinder. Very loud drawing attention to themselves. Also they would ruin the seat. Hard to ride without a seat you know.

UPDATE: I no longer use the seatylock at all since the seat snapped off the lock portion…..and I never heard back from the company either about replacing it, so in the trash it is goingSo the idea is awesome and super convenient; I was very excited about having one less thing to carry around. That being said, this is poorly constructed.The comfort of the seat is passable, not the most comfortable but not the best either.The issue comes with the actual tabs that hold the seat down when you are riding on it: they are made of plastic! They broke on my first outing so now the seat doesn’t stay down while it is attached to the bike. In fact, the entire folding bolt is cover in a hard plastic layer that came worn down in the sections of the plastic that touch the metal lockThis doesn’t affect the locking and unlocking of the bolt and is probably still relatively secure, but the seat now bounces up and can pull the seat off the holder.

The best bike lock is the one you actually carry and use. I won't accidentally set it down or forget it because I'm pretty sure I would notice if I was riding without a seat.After 200 commuter miles it seems durable and comfortable, perfect for my use. It's a great value, costing as much as a regular FoldyLock but with a novel attachment that you don't even notice until you need it.The only problem is that it raises the seat. I'm freakishly tall so it's not a problem but shorter riders may want to keep the box for returns.

Brilliant lock fits very easily on the bike. Now just another adapter for my other bike.

It's a seat, with a lock! Not only that, but a really good quality lock.I found this from BosnianBill on YouTube, and is probably the best bike lock I've ever owned

I participated in the Kickstarter release of this product line a couple of years ago. When I upgraded my cycling to a touring bike this year I ordered this product to go with it. I've been riding with it for three months now and it is just as good as the original. I do a lot of urban cycling in San Francisco along with weekend touring rides. It is particularly helpful to be able to lock my bike downtown in SF and not worry about losing my seat (which has happened with other bikes over the years).
