Seatylock Viking Bike Chain Lock with Key – Magnetic Patented Sold Secure Silver Rated – Heavy Duty Anti Theft – Smart Ultra Security Bicycle Lock (43.3 Inch) by Seatylock

Just got this in today. Upon first inspection it seems quite heavy duty and well made. I watched a few reviews online and all seemed pretty positive. The entire chain is covered in a nice material and the locking mechanism is nicely covered in neoprene. It’s quite heavy, so thinking in a backpack is the way to transport it. However, I then thought if you don’t mine undoing the lock, you can wrap the entire thing around the frame/and or seat post relocking it, and then it’s carried on the bike with no backpack required. Went out and tried that theory and that works great. I’ve also seen you can wrap them over your shoulder like a sling, but don’t think you’d want to ride very far like that, as it’s probably 5lbs give or take. The magnet is very nice, it comes with 3 keys and you can register for free replacements for a few years if you lose them. Overall seems like a solid purchase a few steps up from a basic cable lock.

If you’re looking for a hefty, well made, extremely strong lock, then this certainly ticks all boxes. This is a very substantial, versatile chain lock. Of course, no lock is going to be 100% secure if the thief is persistent enough, but this one is both strong enough and designed well enough that it will be a challenge to defeat and make a thief think twice.

The chain section is very chunky and strong, and it’s covered in a waterproof material, protecting it not only from the elements but adding a level of protection from cutters. The lock mechanism is nicely thought out and is extremely secure.

Though this is marketed as a bicycle lock, I feel it’s too heavy to be carried around. It could be left permanently at a bike parking spot, I suppose. It’s more suited to locking gates or securing larger vehicles like motorbikes and scooters.

As locks go, this is an expensive one, but given how strong it is, I feel it would be a worthwhile purchase to secure a valuable bike, scooter, motorbike or to protect property.

This is a fantastic lock. I opted for the 140cm version, so it can make it through the frame and front tire and whatever column I’m using to secure it.

The quality is excellent, the price is very competitive with the higher strength Kryptonite locks and Litelok, Hiplok, etc. Considering it’s going to take 20 minutes to angle grind through this thing with multiple discs, I’m going to say it’s enough of a deterrent that the extra money for the others may not be necessary.

The lock cover is plenty soft and hasn’t scratched my bike in any noticeable way, and the magnetic closure is something I didn’t know I needed, but it makes locking this so much easier, because the chain doesn’t fall out while I’m using the key.

It’s 5 lbs, so I wear it over my shoulder and across my chest when I’m riding my bike.

This review is for the 110 cm (43.5 inch) light/silver version of the viking.

I spent alot of time looking for a decent lock..went through everything from kryptonite to hiplok to cheap masterlock shoe-string cable locks. I wanted something light and long enough to comfortably carry over my shoulder (like a sash), yet strong and solid enough to secure a mid-range (in terms of expense), nice looking bike. I wanted a chain as U-locks are too limiting, especially in the few spots I have to leave my bike regularly.

This thing hit every mark! I’m no bike lock expert, but to me? This thing is beastly, definitely overkill for my area where alot of people leave their bikes entirely unlocked for hours at a time. Cable locks are the norm around here, even on E-bikes..but theft happens everywhere and it does occasionally happen here. I’m in no way suggesting you do so, but you could probably (for sure) use this thing for self defense if someone tried to steal your bike out from under you. It feels very well made, and the lock itself is by far the smoothest I’ve ever used on a bike lock..no sticking or anything, and the magnet is a nice feature. Easy as pie to lock/unlock. Mine came with 3 very nice, car-quality keys and a code to register them.

The chain links themselves feel solid, certainly hefty enough for a silver rated lock, but realistically could still be cut in a few minutes if a thief had the right tool..it would definitely take two cuts to defeat however. Being a silver rated lock, it should be able to withstand up to 3 minutes of persistent attacking by a determined thief with tools (bronze is 1 minute, gold 5+ etc). Also, the neoprene feels to be high quality, it won’t be easily damaged from general daily use and is sufficiently waterproof.

All in all I’m more than happy with it. I don’t even notice that I’m wearing it after a few minutes with the way the weight is distributed, but it may be too heavy for some..and it would not be convenient to transport on a ride without wearing it over the shoulder..way too beefy to wrap on the bike itself imo, and would add significant weight to a pack..I can only imagine how hefty the gold version is, but I’ll still be getting one when I get a nicer bike one day!

Edit: a larger person may want to get the 55″ if they want to wear it sash-style, I’m relatively skinny at 135 lbs and the 43.5 fits perfectly with little slack.

Love this heavy-duty, weighty and highly functional lock. Great size, safe, and easy to use.
