Getting a new bike, had stopped using the ground anchor and old chain once the last new bike was no longer new (rural location, low risk for bike theft). New bike ordered, at which point I realise I've lost the keys for the current padlock, which is locked to the chain but thankfully not in a closed loop. Considered how to break it, given workshop, time and mains power - and soon realised it would be a long tough job. And that realisation meant buy another one, because your pride and joy's security requires exactly that level of deterrent.

I've purchased the 16mm chain 4m, noose end, roundlock. I've attached it to a concrete pillar (2m of perimeter) and to my back tyre. I used the figure 8 configuration. One single roundlock was enough for it.

The chain is absolutely heavy! It came in a small box although weighting about 20kg!

That's definitely a chain that would hold strong enough with bolt cutter attacks. I leave it in an underground car park, so it should be fine with grinder attacks, as they would be really noisy.

The price was really good compared to competitors and cost benefit. The delivery worked really fast.

Would definitely recommend.

This, is a seriously hefty piece of kit. Coupled with the Beefy bridge ground anchor, I don't think my motorcycle has ever felt this secure. There are heavier duty options available, but the 16mm chain package was much more within my budget and it's more than sufficient for my needs. It might seem pricey, but when you see the chain, you realise that this might be the last motorcycle chain you ever need to buy. A worthy investment I think. I did find that the 2m chain with a noose also links my Bandit's back wheel to the exhaust downpipes for a fairly decent deterrent on a long city break away. Not that I'll be in the habit of hauling that chain round often!

Amazing chain and easy to use roundlock (bought 2 of the locks, so one can be a disc lock) Paid the extra £4 for same key access to both locks. This is a serious bit of kit. With hindsight perhaps I should have bought a longer chain. The 1.0m is ample but I won't be able to attach it to a lamppost or similar. That said, it does exactly what I wanted, but with extra bells and whistles. Supoerb service from the team and next day delivery from DPD. 10 out of 10

Having lost two bikes to angle grinder equipped thieves, I was looking for something VERY secure. I went for the 16mm chain plus Roundlock, and also two D-locks. All came keyed-alike, with great service. Based on the experience so far, I'd give this top recommendation.

A recent burglary made me rethink security and, after a Torc ground anchor was given to me as a gift (also brilliant by the way,) I invested in two 16mm chains and Roundlocks. Superbly finished - who knew chains could be attractive! - with neat finishing covers attached securely. The round locks have a deep polished finish and smooth locking action with quality keys. I can pass the 16mm chain through the frame on my KTM 990 to give an immovable link with the ground. My other bike, a Trophy 1215, has fewer secure body parts accessible but 2m of 16mm will wrap through the swing arm rear wheel and shaft drive support (just!) with no trailing chain on the floor. I wouldn't hesitate to recommend any of these products, their success in various publications and tests in entirely justified. Add in excellent customer service from the team, extremely prompt delivery (1 day in my experience,) and tracked DPD next day I couldn't be happier. Thank you - sincerely!

Really good quality and the round locks are far more secure than a padlock. Was able to get the chain out to me next day delivery also. Very impressed.

i purchased my chain + lock package after geting one of my bikes nicked in central london, i am a happy customer using the pragmasis security for years now, great products worth the money and an excellent customer service with professional approach.

I had a few issues as to whether the chain would fit my Yamaha xmas I have on order.The guys at Pragmasis did a load of research for me to check measurements etc. very helpful! Its a fantastic product and an extremely strong chain!

My first purchase of a motorcycle security product. I must say great reviews online, You Tube and Security for Bikes customers lead to my purchase. Superb quality of both chain and round lock. I should have purchased the ground anchor and most likely will be purchasing the security pin.
DPD delivery service was superb easy to track using the DPD App. The information provided was updated regularly and spot on. My order arrived undamaged on time couldn't be happier. Great customer service thank you.

1.5M x 16mm Chain with RoundLock. This chain is HEAVY. On looks alone it is bound to be a huge deterrent. Brilliant customer service - kept me updated from the minute I placed my order online through to despatch.

Amazing product.
There is nothing like this in the market.
Best security money can buy.
I will definitely buy more products.

Purchased 16mm Noose Chain and Roundlock Package Deal, D-Lock, Anti-Pinch Pin Washers and another Roundlock. High quality items from a company with brilliant customer service. Thoroughly recommended.

Hi, I have now put the chain and lock securing my 3 bikes. I went for a chain length of 4 metres with the Roundlock. This is really top quality kit and should deter the most determined thief. The service that I received from the Pragmasis guys was second to none. Highly recommend.

Contacted David to discuss securing my collection of classic motorbikes. Ordered 16mm chain in various lengths and 4 roundlocks, 3 D locks and two ground anchors. All arrived next day and the quality is excellent. First class service and highly recommended company to deal with.

I bought a 16mm chain with Roundlock after reading reviews and comparing with similar products from the competition.
Having received these less than two days after ordering I am very happy with the lock/chain combo which should keep my bike safe.
I would also give my appreciation for the customer service which was faultless.

Just had the chain a few days and can already say, better than anything I've had to date. I got the 16mm with the round lock. Honestly wish I had discovered pragmasis before. First purchase, won't be the last!

Very impressed with quality. Hopefully will never have to put it to the test but feel a lot more comfortable parking my bike at night!! The roundlock seems like a fantastic bit of kit. I bought a second one with the Key a like option and will use the second as a disk lock. Very very solid and looks far stronger than my abus disk lock which was three times the price. Got quick, friendly reply from David with updates on the order and arrived in two days. Great service. Def recommend.

Very high quality items looks and feels strong, nicely made fantastic buy highly recimmend

The Protector 16mm Chain and RoundLock are a great solution. Together with the Torc Ground Anchor installed in fresh concrete, they give the best possible security for my vehicle transporter trailer. David Briggs was very responsive and his pre-sales advice extremely helpful in selecting the right products.

Bought the 16mm chain (2m long) and 2 SFB RoundLock. About ten days later they have been delivered which is quite fast )Pragmasis comment: This gentleman is outside the UK.] The combination of the chain – locks seems very secure. I surely recommend it.

Ordered and delivered promptly. Excellent product. David then gladly replaced chain after I realised the 2 meter version I had purchased was too short ! No quibbles. Even offered their delivery service which was much cheaper. 1 st class service. thank you

I ordered the 2M 16mm chain and RL21 padlock at around 5:30pm and has an email response almost straight away from David with information as to when my order would be sent, and it arrived bang on time. I've been using the chain and lock for just over 1 month now and it's been brilliant. It looks the part, and has enough length to lock to the floor or loop around the wheel and frame.
It is a heavy old lump, and I can really notice when it's in my top box, but for the peace of mind it's worth it 100%.

I purchased a 16 mm chain and roundlock package. These speak for themselves as they are exactly as described, fantastic. I am now so assured my motorbike is safe and secure, after having one stolen. What I was really appreciative of was the friendly, extremely quick, efficient and fantastic service. Would recommend this to everyone. Thank you pragmasis.

I don't need to go into the chain as that speaks for itself, one of the most secure chains money can buy. Needed the chain next day for a long bike trip and they fulfilled on that promise. Buying all my chains from SFB from now on.

Ordered this 16mm chain and RL21 padlock from germany for my BMW GS: Great and very heavy chain with a formidable RL21 padlock (ordered just another one to make two small loops for example). Although the chain is heavy (more than my normal luggage) its IMHO a good balance between the quality, price and weight. No problem to take it with me (topcase and two big side boxes). By the way, fast delivery and highly recommended stuff!

Did a lot of research into which chain to secure my bike with. Pragmasis came out on top due to their high quality product. When you pick up the chain you can tell it is very strong and the lock is just as sturdy. I collected from their factory - they were very friendly and helpful.

I was surprised by the sheer size of the 16mm chain. It's Huuuuge. Ahah. I can't even imagine the 19mm and 22mm chains. Anyway, I'm very please with this chain, I will probably sleep more comfortably at night, despite having the motorcycle insured against theft. But knowing that I won't need to go through all that insurance nuisance, just makes up for this chain.

Awesome quality chain. And im really impressed with the Roundlock, genius little bit of security, with an excellent fit to the chain and perfect as a disc lock.
Ordered two and chose the "keyed alike" option, meaning i can use the one key for both securing the chain and popping the disclock on. Reccomended

Looks and feel solid, built well! Fast delivery and great communication.
