We recently received a sample of the "Mighty Amsterdam" lock.
It's a bicycle look which looks a bit like the sort of wheel lock used on virtually every utility bike in the Netherlands, but it's not actually one of those. Amazon describe it as "Straight from the Bicycle Capital of the world", but it's not really that either. I've only ever seen one of these - our sample. Some retailers say it comes from Germany. I suspect it may really be made in China. In any case, it's merely a pretend "Dutch" lock and really not the same as a proper one.
How "not the same" ? Well, I'll show you. H@rry made a video of me at work a few days back demonstrating the lock. "Lost" your key ? No problem. A little bit of effort and it pops open without one:
The next day, my colleague Roelf found a slightly faster way to open it. Upward pressure is enough every time:
OK, so you can argue that perhaps it's a little less easy if it's mounted on the bike. That might be so. However, I still think it won't be difficult to open. And besides, why take the risk ?
A proper Dutch wheel lock
If you want a lock which mounts permanently on your bike and is actually secure, then what you need is a proper Dutch lock. The AXA Defender is one of the very best.
These are what we fit by choice to our own bikes. They're robust and reliable. Well made.
Optional cables and chains fit to a socket on the side for additional security without having to fumble around for a key.
You can buy the AXA Defender as well as the add on cables and chains (including the ART approved DPI 110) in our shop but we don't, and won't, sell the Mighty Amsterdam or similar not quite real products.
Many quality products are made in China these days. The "Mighty Amsterdam lock" isn't one of them... Oh, and AXA aren't completely blameless. While the "Defender" really is very good indeed, a few of their earlier models had a fatal flaw and should be replaced.
