Bicycle thieves are often smarter than the technology that is supposed to put a stop to them.
But the Hiplok D1000 bike lock now wants to make it even more difficult for them.
To do this, the manufacturer relies on a material called Ferosafe, a composite material made from graphene, which is said to withstand even high-performance angle grinders due to its chemical and physical properties.
If a thief still tries to do it, he will destroy his tools but not the lock - at least that's what Hiplok promises.
But the promise has its price.
At 280 euros, the 1.8 kg U-lock is not exactly cheap.
It can be opened with three coded keys.
If one is lost, the rightful owner can get a replacement.
