Heavy Duty Bike U Lock with 4ft Flex Bike Cable and Sturdy Mounting Bracket - 16mm, White

I have held off on buying a ulock because I have two water bottles holders mounted on my frame for long bike rides and most ulocks have to be mounted on the frame.This mounts on the seat post and can be installed in a matter of a couple minutes with just a screwdriver. I have a msall saddle bag on the back of my seat and no issues securing both the ulock and the small bag.The cable is nice as well if you live in a city that isn't very biker friendly like mine and doesn't have bike racks to mount it to. The lock is too small to go around a street light post and the cable is cable is long enough to use to mount to a street post if there is no bike racks nearby. The cable is also nice for added security if you run it through the wheels and attach it to the ulock when locking the frame to the bike rackI also own a scooter and if you can find a bike rack this works great for securing the scooter by putting the lock behind the front wheel in the frame and if no bike racks then I wrap the cable around a street post and put the ulock in the front wheel of the scooter and secure the cable that wayWith the seat mount if you have a bike rack on the back,, the lock will extend past the rack by ab out a half inch but that isn't a big deal. I have a small saddle bag on the back of my bike seat and with that and the ulock there is no room for the cable and I get around that by having a bungee cord on my bike rack and securing the cable that way and if I need to use the rack I'll just throw the cable in the bag.

Great bike lock would buy again , buy it

Es muy útil, y aparenta ser resistente, lo único es con la cerradura que a veces da problemas para abrir, pero uno sincroniza bien la llave y la cerradura y aplica fuerza se abre ...

Another great choice to lock my expensive ebike. I love that it is pretty hefty and ease of use!

Just the size I was looking for.

I've had this thing for less than 6 months, and already it has jammed. Neither key is working to unlock it, my bike is stuck locked to a public bike rack, very frustrated.This lock is cheaply made, the keys bend easily, and it is not big enough to go around both your frame and front wheel. I wish I'd opted to buy a more expensive, better made product, because now I'm going to have to pay a locksmith to release my bike. Don't repeat my mistake, do not buy this!!!

On several occasions I had people (aka thieves) trying some brute force and all kind of tricky tools to pick off this lock and cable but luckily for me it held up great.

So I’ve had this since October 2023, and have had no complaints until now. It worked great and made me feel safer until today it just didn’t. Completely randomly the lock wouldn’t open. I was stuck somewhere until by some miracle I got it open. the key is still stuck in the locked won’t move. I don’t know if that’s a risk you want to take.
