Heavy to transport

Haven’t used it as yet so can’t comment on security, but it seems really robust. Haven’t used as yet because I want a mount for it as it’s pretty hefty to carry round otherwise, and I need to travel light. Website states mount is sold separately but can’t find it on the site anywhere?

Very happy

A little bit to small however it will deter thieves from attempting to steal. Its pretty solid and well built

Excellent lock

On the heavy side but kept my bike safe for a couple of years

Prevented two theft attempts

I’ve had two of these and I’ve come back for a third. First one someone tried to saw through and from the cut left behind I’d say it was definitely a powered saw managed to get a dent into the mental but didn’t get through.Second one they managed to claw a good amount of the plastic casing but didn’t get anywhere with the metal.

Great mini bike lock.

Great quality bike lock, you need to be a bit creative at times to fasten your bike to something immoveable but for my fixie commuter it's perfect.

I'm sorry to read that your bike lock broke the first time it was used. Please feel free to return it to us for an exchange if the item is faulty. Can I also ask you to give me some more details as to the nature of the fault as I wish to forward this on to the design team at b'Twin.

The Bike's Not Been Stolen Yet!

It's small and so the bike has to be close to whatever it is that you're attaching it to. It was never going to be light. But it's terrific. And the price is what makes this so attractive. The security rating of 8 meant that I thought it'd be fine for my £600 road bike to leave around the city of London. I've used it in conjunction with a cable to secure the front wheel. So far, it's been kept safe. It comes with three keys which have been placed on separate keyfobs! It's the business. I've bought three so far for my kids' bikes as well.

Waste of money difficult to un lock

I am extremely disappointed I brought this lock for my son aged 14 he cannot use lock very difficult to undo I tried and I found the same problem it also does not fit well . The fact you cannot undo easily It is a waste of money as I am going to have to purchase another one

I'm sorry to read that the lock does not function smoothly. Please return it to us and we will gladly exchange it for you.
