About the Product
The SIGTUNA model WODAN-16 is quite literally a tough nut for bike thieves to crack since it incorporates what we call Viking-strength steel; 16mm bars manufactured from specially hardened steel locked into a Double Bolt Locking Mechanism, which offer protection against even the most determined of attacks.
This Kryptonite KryptoLok Series-2 Mini-7 U-lock delivers high security in a compact design, helping keep your bike protected.

What customers say about "Key Specs"
Sigtuna FBA_Wodan 16mm Heavy Duty U Lock
  • The locking mechanism appears to be solid and should be adequately resistant to being forced or picked.
  • The u-bolt is very solid and the cable long enough to secure the bike. I carry it in a backpack and weight is not a big problem.
  • The U-lock feels very sturdy, it's heavy and doesn't feel cheap. It has a rubber coating to prevent scratching the bike, which is a nice touch.
  • One sturdy solid bike lock. 16mm of steel is no joke. Definitely wouldn't be easy to cut through. Love the quality of the laser cut stainless steel keys.
  • It is easy to open and close with the provided key. It's sturdy and heavy and I feel comfortable in leaving my bike out with this lock.
Kryptonite Kryptolok Series-2 Mini-7 Heavy Duty Bicycle U Lock
  • I like the smaller size which fits on my seat stem and drapes over my seat post carrier pack. It's small but strong.
  • There is a way to defeat this lock, but it isn't something that anyone but the most elite criminals would do for a bike.
  • I love the lock. It's sturdy and seems like it will definitely deter theft attempts -- and make a successful theft extremely difficult.
  • Works great and is easy to operate. Bike holder is almost useless! I always put my lock into a bag on the bike rack.
  • Sturdy build. Mini U locks are the way to go, as there is little space for thieves to work with.
  • This lock was always hard to open. Putting the key in the lock would not result in consistent opening and have to jiggle it just so to open.

What customers say about "Features"
Sigtuna FBA_Wodan 16mm Heavy Duty U Lock
  • Absolutely the best lock for the price, little bit cumbersome but the bike lock mount makes it much more manageable. Value against price, can’t beat it.
  • The rubberized coating on either side of the keyhole, along the base, is genius! I can tell this will come in handy while trying to lock up my bike in a downpour of rain.
  • The versatility in positioning the mounting bracket, plus the quick release button is fantastic.
  • The mount is incredibly easy to install and has been very sturdy so far. I don't think I've had any issues with theft, but I'll post an update if any sort of attempt is made.
  • Very thick and durable plus easy to attach and use. I have no concerns my bike will be stolen now! Comes with a cable too so I can lock up the wife's bike also!
Kryptonite Kryptolok Series-2 Mini-7 Heavy Duty Bicycle U Lock
  • Thus far the lock has done its job! I will say the mount that comes with it is a little cheap, but it works.
  • It works like it should - the keys work fine, the plastic covering doesn't scratch the frame.
  • Great product. Feels like it is made solid. The bike mount is great as it does not scratch your frame and at the same time you do not get any vibration/movement.
  • It's brilliant, nice color, light and it works since I just have huge pliers and hammer marks all over it and the mf clearly had to give up on stealing my bike.
  • The mounting system is surprisingly secure; I haven't had any issues with the lock shifting/rattling while I ride.
