A sturdy lock at a good price
- 19/07/2023
These locks seem very well made while not too expensive. They are heavy. I got a 26 cm and a 30 cm one, with the keyed-alike option (that means six identical keys) and this makes life much simpler. Getting the keys right and all the way to the end can be a little tricky, you have to handle things methodically.
Ces antivols sont bien fabriqués et pas très chers. Ils sont lourds. J'en ai pris un de 26 cm et un de 30 cm, tous associés à un même jeu de clefs (soit six clefs au total) ce qui simplifie beaucoup les choses. Il faut s'assurer de bien rentrer la clef droit et jusqu'au bout ; il ne faut donc pas se précipiter lors de l'installation du U.
[ Pragmasis Comment: Merci beaucoup pour votre Francais. Pardonez mois que notre 'website' est seulement en Anglais. Ma Francais est tres mal. Encore merci beaucoup :-) ]
DIB D-Lock
- 25/05/2023
Appears to be good quality at a good price.
I bought the 130mm to go around the frame spar of an enduro bike then a 16mm chain down to a ground anchor as there was not enough clearance for the chain to go around the frame direct.

Amazing service, ordered one day and delivered the next. Great price for a very heavy duty D-lock. Couldn't recommend it more.
Great lock
- 21/01/2023
Bought the 190mm to lock through my front discs on a Moto Guzzi V85TT with spokes and large centre hub. Couldnt get the roundlock to fit the disc but this u bolt fits through both discs and spokes neatly. Can also add my 16mm chain if needed. Great versatility and value for money.
Almost made to measure
- 06/12/2022
having a BMW C400GT with quite small wheels I was unsure which lock to get didn't want a disc lock as the discs were small,
so opted for 2 of these Locks 130mm and 190mm with noose chain for when required,
they both fit perfectly 190 on front and 130 on the back, great quality and good value in my opinion
Dib-D lock 130
- 26/11/2022
I have purchased three of the locks and they are perfect, well made, study and easy to use. The "130" will fit in the swing arm of a 2021 Triumph Tiger GT Pro 900, the swing arm of a Suzuki GSXR1000 and the frame/rear sub frame of a 2018 Norton Commando 961 (and the latest TVS versions). Great service as usual from these guys.
This thing is quality - DIB D-Lock Internal Clearance - 190mm x 87mm

Fits Honda NC750X. The discs on Honda NC750x are thin and can be easily cut with an angle grinders. I was initially looking for the round lock and approached Pragmasis who quickly advised that I should instead go for DIB D-Lock and put this lock around the brake caliper going through the wheels and locking it on the otherside.

If you watch the videos you will see that it's Diamond Grade rated for Motorbikes unlike the Abus and others which are Diamond rated for cycles. It's heavy and really hard to bypass, I have tried trust me! The lock is secure and comes with 3 keys. Sadly it doesn't fit on the back of the wheels (I mean it does but there isn't any advantage). Pragmasis also offer key'd like option which is great and none of the other manufactures offer this options. It is also quite narrow and first time it took me 2 minutes to lock and 10 minutes to unlock but then I got a knack of it and I can lock and unlock in 10 seconds. This thing ozes quality when compared to ABUS which was £140 upwards compared to this one.
[Pragmasis Comment: Correction: The DIB D-Locks are Motorcycle & Quad & Scooter Gold, Bicycle Diamond rated. The certificates are on the website at: https://securityforbikes.com/certificates.php
We have several other products that are Motorcycle Diamond rated, such as the Torc Mega & Maxi anchors, plus the Sub Major. I hope that clarifies.]
Dib-D lock 130
- 30/05/2022
Early days with this versatile lock, but appears quite solid and good value, when compared to others on the market. Pragmasis had this ready for collection, just a few hours after my order. Really pleased so far with the service and quality from Pragmasis.
Great on its own or with other Pragmasis products
- 27/04/2022
A great, strong U lock on its own and part of my solution to locking 3 bikes to a tree in London: 4 metres of Pragmasis 16mm chain goes round the tree (the chain threads through the extra-large loop at the end); then the U-lock locks the back wheel of the first bike to the chain; the middle (most expensive) bike has a Pragmasis anti-pinch pin through it's rear wheel tube, which a link of the chain goes over; it then goes through the rear wheel of the last bike and the end goes back to the anti-pinch pin. The Squire SC65 locks tightly on to the anti-pinch pin, holding both chain links in place. Very reassuring.
Fantastic locks and great service
- 25/04/2022
Following David's very helpful advice about securing several bicycles with one chain (apparently, thieves will cut the frame of the last bike so the remaining bikes are unprotected), I have bought D-Locks to fasten the bike rear-triangles directly to the chain.
As with my previous dealings with Pragmasis, I am so impressed with the level of service, advice and quality of the products. The locks incredibly solid (as are the chains & ground anchors). No bikes are leaving my garage without a considerable fight!
Great products and service
- 19/02/2022
Couldn't be happier with the products and service. If I need anything else this company will be my first call. Thank you.
Another great service!

Just taken delivery of another Dib-D lock to secure my new lawn tractor. I have purchased many products from Pragmasis and I must admit that their service is superb and their products are first class! Many thanks
Motorcycle Security

Bought four of these (keyed alike) to secure my motorcycles to a Pragmasis ground anchor and chain and they are ideal. Reasonably portable too for use as a disc lock and have even used them to secure my more expensive bicycle on rides out. Delivery times were excellent and I am very pleased.
Great for disabled use
- 19/11/2021
As a disabled user of a mobility scooter I needed a secure lock to match with my 16mm chain secured to a wall mounted anchor. The close shackle padlock I have been using was difficult for me to use as I have limited strength in my hands and lower arms and having to lift both ends of the chain to loop 1 link through another and then trying to fit and lock the padlock whilst fighting with the rubber flap was a nightmare.

This product has changed the situation completely. I now only need to use a single length of chain and I can easily attach this lock with the chain to a strut on the scooter. The fact that the shackle is also 16mm means there is no weak point in the system. I can highly recommend this lock to disabled users as it is much easier to handle than an equivalent padlock.

Finally great service - received the day after despatch and excellent communication.
[Pragmasis Comment: I am very glad you are finding this helps your situation. My father had only one hand, and Sarah, my (very sadly late) wife that setup Pragmasis with me had Cystic Fibrosis so I have a little experience of people dealing with issues that others might not even notie. If we can make life a little easier then we have achieved something. Thanks for bothering to say. Very much appreciated.]
Awesome lock system
- 27/10/2021
The lock itself is great, and I love the option of using different-length shackles according to the situation.
Robust and easy to use
- 09/05/2021
Used to extend a chain from Torc Ground Anchor. Feels very strong easy to use
Solid D lock
- 19/03/2021
Bought this to attach to ground anchour. Lock is well made and sturdy. The D part seems to be thicker than most other dlocks I've seen.
Very solid lock
- 10/01/2021
This came super quickly and seems exceedingly study, they were more than happy to make the keys for both match. Very happy with it.
Great lock and customer service
- 08/01/2021
Excellent sturdy feeling lock. Fits well following good advice from customer service before ordering. The customer service were very helpful in changing a previous lock I bought for this one and very fast and responsive. 5 stars in my view!
Very pleased
- 05/01/2021
Lock seems very sturdy and suits our purpose well. It arrived well packed and exceedingly promptly, with great customer service (detailed shipping info) from Pragmasis.
Superb D lock especially for the price
- 21/10/2020
Solid reassuring D lock. I used these on my scooter to secure both wheels through front and rear forks using two different lengths.
Great products, Great service
- 05/10/2020
Bought DIB D-Lock with Protector 13mm chain and Shed Door Beef-up kit. Just waiting for delivery of Shed Shackle to complete the package. The products are real solid security kit and worth paying for quality for peace of mind. The service provided by the company is superb, happily offering great advice and updates on status of my order.
The videos and links give so much useful guidance to help make purchasing choice for a secure setup.
DIB D-Lock
- 27/09/2020
Absolutely brilliant, I bought two for added security for my bike.I got the smaller version which fits perfectly as a disc lock through the rear wheel of my bike,I also bought a RoundLock padlock which is also excellent for the money, it can be used as a smaller portable disc lock ( make sure it will fit your disc first) or with the chain , highly recommended.
Very Sturdy D Lock
- 24/09/2020
T DIB D lock is very sturdy, it is also quite heavy but that is good. The red finish of the body stands out well. The locking mechanism seems to work very well.
Go for the 30 mm
- 06/09/2020
Great bit of kit, went for the 30mm as it allows me to tether to something that I can get the bike close to whilst on my travels. Go through the wheel amp some frame too. Also can stick the business end out of my cover just to deter any tea leaves having a think it may be less than protected.
Fantastic lock
- 21/08/2020
Really impressed with the DIB lock right from opening the packaging. Beautifully made, tough and heavy. Nice touches like the soft rubbery coating on the shackle and the cover over the key hole to prevent water ingress. To be honest, it makes my ABUS Granit X 540 look a bit weedy! Will have no qualms about locking my bike with the DIB!
Looks the part
- 13/08/2020
Easy to fit on the bike, and looks solid. A mate of mine joked that if I forget to remove it from my front wheel, I'm going to snap a fork leg. Not going to leave my bike without it.
Complete products - all aspects have been thoroughly thought through
- 03/08/2020
I bought 2 D-locks and an extra shackle for mixing up my locks between home, on the road, in dicey neighbourhoods, and in storage over the winter.

They are really solid locks - definitely worth the quality reviews and certifications. The finishing is great - rubberised around the shackle to protect your wheels and satisfying 'clicks' when sliding on the lock as well as closing the dust cover.

Keyed-alike makes them perfect.
Super strong, and excellent value.
- 10/07/2020
Great that you can order different sized shackles, making it very versatile. A bargain when you see how much other 'name' brands charge you, for an inferior product.
Excellent customer service, and fast delivery.
Very handy, very portable, very strong.
- 05/07/2020
The D lock is a fantastic addition to a chain and round lock set up. It gives you so many options to secure your bike. It’s very flexible in its uses and is very portable. Many thanks to David for helping me to select exactly what I needed to provide the best security possible.
