Decent lock

Purchased this lock along with my RC120. Not a bad lock, but a bit on the small side. Still gets the job done, however if you are purchasing this lock for a large frame bike I would recommend going for one of the bigger locks Decathlon has to offer.

Bike U-lock

It is a bit small, but I use it with a cable to wrap around one of the wheels. I like that it is hinged so it does not come apart. I had one before and it would come right off, making it hard to handle.

One side stays connected nice

Its small sometimes can't fit around the post and my bike frame. I love how one end stays connected. Works great. I've used it 4 weeks mon-friday had no issues at all.

Doesn't lock properly, you need to turn the key about 20 times to unlock and then sometimes it won't lock/unlock. Very tight and stiff key operated lock.

Nice size D Lock.

Just the right size and weight for a lock that you can carry in a small back pack or even in your cycling top I imagine, I haven't tried that though! Should stop all but the most determined thief!

Fell apart

The lock just fell out of the end so it is useless, I literally took it out of my bag and it was in pieces, how can it provide any security if it can fall apart on its own?

Hi John,

I am sorry to see this happened. It is highly unusual that this sort of thing would happen. I would encourage you to bring it in store so we can look at it and see whether we can do an exchange, perhaps there is a model more appropriate if you have lost faith in this one.

If you bought online and going in store is not convenient please email with your order number and photographs illustrating the issue. We can then advise you on how to proceed.

Lightweight and neat looking

Great for short stops to the supermarket, gym workout etc… wouldn’t trust to leave in public place for long periods or overnight. However for price it isn’t designed for maximum security but basic protection and a peace of mind.
