Hardened steel has been the most popular choice for bicycle lock manufacturers. Despite their solid appearance, these locks are still susceptible to an angle grinder attack.

But what if we create a lock from one of the strongest materials known to humans? Well, that is exactly what Hiplok just did.

The company released D1000, a bike lock that combines graphene, which is stronger than steel but a fraction of the weight. The result is a U-lock that is 20 times more resistant to angle grinder attacks than your regular lock.
