This package deal arrived the following day mightily impressed straight away. All keys cut the same as requested and work on both locks. Female locking body for use on the chain works as described in video. Standard female locking body works as disc lock if required on second lock but take note of sizes as it may not go through or if the aperture is too big it will simply fall out. 2 metre chain nicely protected for threading through where required. And at this length and this section of chain you will need that as it is heavy, it is not unwieldy but you need to be mindful when locking up your pride and joy. A Very satisfied customer.

Great service, questions answered quickly and thoroughly. Product arrived quickly. Piece of cake to fit. Looks high quality... if they steel it after fitting this, they probably deserve it, I know I have made a solid effort to protect the bike using this kit! Thanks

Very pleased with the chain and lock, both look top quality. Roundlock snugly fits the chain so you physically can`t get to it and cut it. I always buy quality items and never look at the price. It`s an investment and I`m confident this combo will last very long time and serve me well. I`ll use it to lock my new motorcycle and bicycle together. Chain will be off the ground and fed through the "Maxi groun anchor" I also purchased with it. Anchor will be fixed to reinforced concrete wall. Chain is heavy but still managable, obviously for home use only, it`s not meant to be carried but everyone who buys this chain size knows that. Colour combination is superb. Delivery was next day after payment was taken, communication with David was excellent. Great company with great values - reputation and environment. I`m very happy customer.

High quality chain and the round lock inspires confidence. David @Pragmasis went above and beyond to ensure I purchased the right kit. Excellent customer experience and very happy with the product. Wouldn't hesitate to recommend to others.

Polite, prompt and very helpful service, delivered quickly. Chain and lock itself work as described, looks heavy duty especially when combined with a ground anchor. Only point to remember is ensure that chain will fit though the frame, it’s large! Very happy.

Absolutely solid piece of kit offering great peace of mind. If someone gets through this then there's not much else that would stop them. Great communication and super quick delivery as well, making these guys a pleasure to deal with, highly recommended.

After 25 years on rat bikes I took out a massive loan and bought a BMW 1250 GS Adventure...only for it to get stolen 3 months later. Insurance replaced it like for like but this one I'm determined to hang on to. Hence scouring the internet for solutions. Pragmasis stood out a mile for me. Solid products, solid people, no bullshit. My chain has turned up and it is everything I expected it to be, and delivered very quickly. I love well engineered products and this is awesome. Not only that but the company appear to have ethics in line with my own, I'm gad my money went with them. A fair price for an excellent product.

If I were a bike thief I’d probably walk on by if I spotted this lock and chain !!!
Great piece of kit and once ordered, I had it the next day. Tracked all the way so I couldn’t miss the delivery.
Very happy

If you're looking for something to lock up your BMX whilst doing your paper round, this is not for you. It's a beast! The lock is very close fitting so I would imagine very difficult to get through and the chain looks like it would scare most thieving scumbags away. I think it's a bargain at this price as well compared to others on the market.

Before buying make sure you have enough space around your frame to put it through as on my Bonneville there is only 1 way of doing it and engine must cool down before chaining.

I live in central London and thanks to this chain I can sleep well again, not worrying about my bike.

Worth every penny, great quality.

Roundlock is amazing and works as a disc lock.

This is serious kit and needs to be handled carefully. A testament to its quality. I cut a slit in the sleeve in order to keep chain tight and off the ground passing through a Torc Anchor. My trailer is going no where. Great delivery, excellent stuff.

Just seeing the size of the chain alone i think would put off most thieves. I'm no expert but the quality seems very good and very impressed with the round lock system. Service was prompt and received the item very next day. Expensive but very much worth it.

Delivered within 2 days, this impressive looking chain is the sort of thing you would use to tether a belligerent Aircraft Carrier to it's mooring!! The compact round lock is a really snug fit inside the links. I feel more confident leaving the bike parked up at work now! Excellent product and great service.

For years had relied on 13mm chain through front wheel and around exhaust downpipe!
Finally got my act together and concreted in a ground anchor which combined with this very beefy chain and lock gives much greater peace of mind.
Also has a nice quality cover which works well when feeding the chain through a smallish gap around the back of the engine.

Top quality chain an absolute beast wrapped in a good quality sleeve with a round lock and a torc ground anchor brilliant communication with the staff came well packaged tracked with parcel force and a day earlier thank you very much.

Obviously it goes without saying, but this is a heavy duty chain, with emphasis on the heavy, so not one to be taking out on the bike. In situ in the garage it's an excellent deterrent, but one that'll likely only fit through your wheel and not the swing-arm for instance, simply due to the size. The canvas sheath does a great job of protecting the wheels etc, although very quickly picks up any oil/muck from the chain if it comes into contact with it.

The Roundlock is the real surprise star of the show though, as it's able to pull double duty as a disk lock when not being used to secure the chain. The package also includes the 'smaller' original locking piece as well as the larger optional part required for the 19mm chain.

I've owned this item a few weeks and being for a new bike I've used it everyday. It fits snugly through the front wheel of my F800R, it also fits through my bike's gap behind the cylinders without issue.
Delivery was great, communication from the supplier was on another level! It's strange how a personal email from an online company makes you feel a valued customer but it does and will influence my decision next time I need to buy a chain. Would recommend without hesitation.

Went back n forth on chain size and lenghts, bought two, this 19 mm and round lock and the 16 with dib lock. This is heavy, well protected quality chain and frankly glad I didn't go up to the 22 cos I don't think it would have fitted round the bike. Paired up with the torx maxic, I think it will def live up to its protector name. Next day parcel force delivery just adds to the great customer service. Thanks pragmasis very happy.

They picked the lock, left the bike and stole the chain ;) It's really great.

After seeing (and lifting) this chain, I was happy I didn't go for the 22mm, it's a beast!
[Pragmasis Comment: Just checking you were joking about a lock being picked??? In our experience it never happens, so I thought I'd just check you weren't being serious?]

After much research I decided to buy the Pragmasis 19mm chain and roundlock and these products truely will deter criminals. Not only am I convinced it will resist most attacks, David and the team did an excellent job advising what product to select for my motorbike. Great value!

Was impressed with the quality off chain and round lock. Bennett’s review help a lot on choice..Round lock was really good…added benefitted can be used as disc lock...so purchased another for the best chain..wish I had found this deal package before …I would off saved pounds…communication with Pragmasis …bang on..thank you.

Forget your chains you can pick in up in certain retail stores. This is a really big and heavy chain and having researched through online videos, both this and the Roundlock are a perfect deterrent for locking your bike at home.

After researching options offered on the web to secure my motorcycle in the garage, bought a 19mm chain, 2 roundlocks and a Double Doofer ground anchor . All were dispatched immediately. Service second to none as is quality of the products. The roundlocks are exceptional also acting as disc locks. So impressed I later ordered the 13mm chain as portable security. Definitely recommend.

Excellent product as I have come to expect from Pragmasis. Service and support also prompt and friendly. I highly recommend. Bike now has 19mm chain with pinch pin and ground anchor :-) Thanks Pragmasis, you emptied my bank but you get what you pay for :-)

A great product and very secure. The matched keys is a nice touch.
Great service from order to delivery, They queried my mistake on the order to make sure I got exactly what I needed.

Great combo,really quick delivery ,I purchased it yesterday and in less than 24h installed.Excellent communication .Thank for this great products

I bought a Protector 19mm Chain and RoundLock combo and Double Doofer Removable Ground Anchor.
It is used to secure by moto in a shared open space garage and combo does its job quite well.

Item details in web site perfectly describe the product and the delivery service was excellent.

I would strongly recommend SecurityForBikes, if you are looking for top quality products and excel service.

Can't comment on its long term use as I've only just bought this combo, but it weighs a ton and is very high quality. I have no doubt that this chain and lock is one of the best options available anywhere.

The chain seems unbreakable. Padlock is also very solid.

Had a minor issue with my order and customer service promptly dealt with it very attentively. Would deal with again.
