SIGTUNA Bike lock - 16mm Heavy Duty Bicycle U Lock Shackle and Mount Holder, 1.2m Steel Chain Cable and 3 High-Security Keys for Road Bike, Electric Bike, Folding Bike, Mountain Bike - Yellow

I have been using this on my electric bike. Its good quality and secure but its a bit heavy

This bike lock is very sturdy and I have confidence it will do the job when locking the bike up in an open space. I have gone for this one along with a small D-lock to ensure both wheels can be locked to the bike frame, which itself is locked to a bike rack, so all a thief can take is the seat. The lock also comes with a mounting bracket so you don't need to lug it in a bag. To really up your bike security, I'd recommend getting this rear-light alarm which is piercingly loud upon detection of vibration, deterring thieves (I am not endorsed by them, this is just a good idea). It comes with a key-fob for remote locking and unlocking, just like a car! And then maybe consider getting a tracking device like an Airtag and hiding it with a hidden mounting bracket as I have done under the seat. With two locks, the alarm, and an Airtag, I feel like no thief can get away with my bike for very long, and it brings me a piece of mind. https://www.amazon.co.uk/dp/B0BZHW4V3M?psc=1&ref=ppx_yo2ov_dt_b_product_details Overall this bike lock is well-built for the price and is a competitor amongst the plethora of bike locks available on Amazon, and I'm glad I went for this one.

Bought one of these lock's for my road bike. I wanted something big and secure looking. On time I recieved the lock, with a strong cable that can be attached to your bike and also help secure the wheels with three keys. My only downside was the bracket that held the lock. While it's screws on very tight it has snapped twice while going down a kerb. Initially I thought it was a manufacturer defect so with the 100% guarantee Sigtuna provides I was sent a replacement with 1pm Special delivery. Unfortunately the bracket on that broke too so Sigtuna refunded me what I paid. I definitely would recommend the lock, I will absolutely keep using it as it does seem super secure and heavy duty but will carry it in a bag. I will certainly look to use more Sigtuna gear after the customer service I recieved. Unlike others I wasn't asked to provide a review for an incentive I just appriciate a good product and feel like everyone should know what a great company Sigtuna is, what a great lock this is but also that the bracket sucks.

The lock is secure, strong and easy to use. I'm happy to have invested in such a lock. I would recommend them to anybody. The fact it has a D lock and a chain works perfectly at securing my bike to prevent theft! 10/10

Bloody good lock. Looks the business, certainly a deterrent. Really substantial barrel lock. I’ve got easy release wheels the cable let’s you strap the front wheel to the c lock. Really impressive piece of kit. Highly recommend.

Good item ,does its job.

Sturdy lock and secure, I would definitely recommend it

Good solid lock and chains easy to use at a good price. Worth investing in for peace of mind when out on a cycling trip.

I use that lock for about 9 months and my bike has not been stolen, so that's a good sign!! 😄 However, when it is locked, it wiggles a bit. I don't know if it is normal.

Tiene muy buena pinta, es robusto, parece seguro.

I wanted to upgrade my bike lock (actually, one of my bike locks - I use two U-locks in the city) to one that was thicker and - more important - has dual locking mechanisms so that two cuts would be required to remove the lock. The Sigatuna is a bit thicker, and has the dual locking mechanism (there seems to be some controversy as to whether its really 16mm or whether that is padded by the plastic coat on the steel - I don't know the answer). I thought the reviews here were encouraging so ordered it. I've been quite happy with it for the 1 month I've had it. Its a bit heavier than my other U-lock (Krypto-Lok) but definitely not "too heavy". And I suspect its much better security. The key has been easy to turn - something that was a problem with the other Master U lock I had that this replaced. I don't use the frame mounting bracket so can't comment on that - I have a rat-trap carrier and I keep it in that secured with a bungee cord. And I actually don't use the cable - and I think its generally a bad idea because all of them are easily cut. I have found that a much more convenient and secure way is to have two U locks. So I have this as my "heavy duty" lock, and a Krypto-Lok as my secondary one (and which fits through the perforations on my helmet allowing that to be securely locked to the bike). A second U lock is so much more convenient to carry than a cumbersome cable. I have the Kryptonite lock mounted to the frame, and keep the Sigatuna lock in the rat-trap carrier. It doesn't offer theft protection insurance - but that doesn't bother me. (1) My bike isn't worth that much - less than the deductible! Well, its wort a lot to me, but not money. (2) Somehow I suspect that the fine print on all those bike lock insurance plans are smarter than most bicyclists - and I rather doubt they really ever pay.
