Kryptonite Keeper 785: When bicycle locks are TOO safe

Bike locks have one purpose only: To protect bikes from thieves. But what happens if it protects your bike from yourself?

Only one month after starting my new job in Zurich, my bike was stolen. And I had made sure to lock it with a massive lock. They just took it, the scoundrels! Maybe I should have chained it to a fence.

I could really do without a nicked bike a month – let alone my insurance – so I needed to toughen things up. So for my new bike I bought an even more massive lock. The Kryptonite Keeper 785. If its name is anything to go by, it’s even Superman-proof. According to several ratings, it is said to be extremely theft-proof and easy to attach to things thanks to its long chain.

I should have known better

Translation: We ordered two locks. Opening and closing them proved tricky from the start and required a lot of patience to get the rotation right. Unfortunately (after a very short lifespan), we can no longer open the locks with their keys and will have to call the locksmith. I would advise against purchase.

Kryptonite is only partially aware of the problem with the Keeper 785. “We can safely say that we have not established a general problem with this lock – otherwise we would no longer sell it”, says Element Sports, our Kryptonite distributor. They also added that they have dealt with the odd broken cylinder in the past but simply replaced the faulty locks in these situations.

We need more power

The lock could feel the heat at the Velotto workshop.

Ten seconds later, sparks were flying and it was a joy to see! However, it wasn’t as easy as it first looked. Even the over 1500 W device was struggling with the Kryptonite. “It really is a sturdy lock”, the mechanic admitted after telling me he was no fan of Kryptonite locks. A few minutes later, the shackle was broken and my bike was free again. I could tell just by looking at it that it was jumping for joy on the inside.

Taking it down a notch

Serves you right, stupid lock.

As a child, I wasn't allowed to have any consoles. It was only with the arrival of the family's 486 PC that the magical world of gaming opened up to me. Today, I'm overcompensating accordingly. Only a lack of time and money prevents me from trying out every game there is and decorating my shelf with rare retro consoles.
