Nice piece of quality kit - solid but portable, extra length gives more security options


Great company to deal with - know their stuff

Excellent service from Security for bikes. Very helpful and friendly.

Product delivery was quick and on time. DPD are their delivery company and have great online tracking systems.

The lock itself is well made and very robust. Excellent price when compared to the other reputable lock companies, Abus & Kryptonite.

Ordered the 19mm version, didn't feel as as heavy as I'd feared. Feels very nice to hold, really looking forward to locking my bicycle with it now! Did lots of research and wanted a serious but portable D-Lock.

Very solid and substantial D-lock 130mm with 16mm hardened steel shackle. Very handy size to carry on my motorcycle it’s really easy to fit and remove, making it a great choice for anyone who makes a lot of stops while out and about. Great product and absolute brilliant service...

Great build quality and fits under my seat for portability. Very happy!

I have a Vespa Primavera and commute into London daily. This D lock had excellent reviews elsewhere and I agree. It’s tough, easy to use and fits through the front wheel and fork nicely. I bought this instead of a disc lock. The weight is reassuring and I ride with it under the seat without issue. Service, packing and delivery were excellent. Thanks.

Good enough for the LockPickingLawyer so good enough for me. Nice solid weight and easy to use. Supplied with three keys which is great.

These are great, I have 3 that are keyed-a-like and have just ordered another. They are very good quality and I know from my own research that they are near impossible to defeat. I matched mine with a 16mm Protector chain, all connected to a ground anchor to give good solution for all 3 of my bikes with no obvious weak point. Steve and his brother couldn't be more helpful - nice to spend money with a quality, small British firm.

Versatile lock with several options on shackle length. Gives flexibility for use with chains. Top class service from and customer contact from Pragmasis!

This is beautifully made. Solid without being too weighty and very slick and easy to lock and unlock. Secure Gold accreditation- enough said

Very impressed by the DIB D Lock. Points to note:

1. Easy attaching and removing of the shackle to the lock body. I've used a number of D locks in the past, and this is one of the smoothest to insert and remove the shackle from. No sticking and no fuss.

2. Excellent coating, to prevent damage to my bike.

3. The little switch/cover to stop the keyhole being exposed to the elements is a very welcome addition. I have had to wash out, and then WD40 and lubricate, keyholes of other D Locks which didn't have keyhole covers countless times, and the fact that the DIB D Lock has a cover for the keyhole makes having to do this far less frequent which is handy.

4. Well machined and smooth, no edges to catch on clothing. I carry the smaller one in my jacket pocket for when I'm out bicycling, and it's no problem.

5. Effective 16mm thick shackle, which is nice and strong, wider than a lot of other D Locks I have used.

6. Keyed Alike is a godsend, it means I only have to carry 1 key for the locks at home and work, for both motorcycle and bicycle.

Ordered one afternoon recieved next day impressed with the solid build of this d lock,already have abus granit which costs more and this is better imho,going to invest in the chain so I use on garage anchor and when on road the lock is mobile,great communication from minute I ordered to delivery this is an example to others top notch.

I placed my order on a Saturday, right before the Christmas holiday season, with a destination address in Germany. The locks already arrived on Thursday (and it would've been Wednesday if DPD didn't mess up the delivery) -- this is excellent. Shipping cost was still reasonable.

The D-Lock quality is superior beyond question. I'd order any time again, thanks a lot!

Been using this on my rear wheel, through the sprocket and spokes, fits perfectly.

Compré 2 D-Locks con las mismas llaves (3 por cada candado; so 6 in total). Había visto vídeos en internet de lo complicado que es abrirlos y cortarlos. Efectivamente, el acabado es de altísima calidad y la medida de 26cms es perfecta para la horquilla de la Suzuki DL650 Vstrom. Lo uso también en Honda NX 250 Dominator y va perfecto, aunque con los radios un candado de U es siempre más incómodo de poner. Muy bien empaquetados (podrían venir copas de cristal sin sufrir daño), me remitieron número de seguimiento con DPD desde UK a España y la entrega fue muy rápida. Los recomiendo sin duda.

I bought 2 D-Locks with the same keys (3 per padlock, so 6 in total). I had seen videos on line about how hard to pick up or cut they are. Definitely, they are a top quality product and the 26cms size fits perfect on the forks of the Suzuki DL 650 VStrom. I also use one on a Honda NX 250 Dominator and it fits great, although due to the spoke wheels it is always more uncomfortable to put it and out. The parcel was really well packed (they could have sent wine glasses with no damage), I had a tracking number to follow the shipment from UK to Spain and delivery as very fast. I definitely recommend the purchase.

Got two of these for the back and front of the bike. Really well made and the order turnaround was quick

I am looking to bulk up on bike security and would definitely use Pragmasis again.

Placed an order for a D-Lock and an extra shackle. The extra shackle was out of stock but I was contacted promptly to let me know this and the D-Lock was dispatched immediately with the extra shackle to follow when in stock at no extra cost to me. I was kept fully informed through out the process. I couldn't be happier with the customer service.

The product itself is also excellent. Very solid feeling and the shackle has a good thick rubber coating so it doesn't scratch the bike. It locks smoothly.

Overall, I am very happy with my purchase and the service I received.

Service and advice was first class and i’m blown away by the quality of the two Diblocks.
I got them to use on my TMax in London. They are super robust, hi viz and definitely a deterrent to your average scrote bike thief.
Fingers crossed!!

Just received a pair of these locks. They should at least slow down any would be thieves, if not put them off all together.

First rate service from SFB and excellent comms from initial phone enquiry to delivery.

I have been using the biggest of the DIB-D-Locks for over two year in Berlin. Nobody has even attempted to steal my bike during that period. What is more, the Lock is still fully functional without any issues. If you have a bike rack, there are some solutions on the market which can be used as a holder for the lock - I my self am using the "Trelock ZB 403 3-Point Lock Holder" which is very good and can be had for around 15€.
Lastly, the company and its customer service are so nice and worthy of your business that I will never buy a product from their competitors.

I've been riding nearly 30 years and in that time security has become an absolute essential especially in my high risk area of Islington N1.
These D locks are fantastic quality and the customer service I received was exemplary. I wouldn't hesitate to recommend these to fellow bikers and as soon as I have the spare cash I will be purchasing their 13mm 1.2 noose carry chain that I got the D lock to go with.
A big thumbs up!

I have two of these and the build of them is excellent
Very strong with a 16mm shackle that’s available in two lengths, plus available to purchase separately.

Substantially well made D lock arrived today only 2 days after ordering. Tracked all the way by DPD, this is the fourth quality product supplied by Pragmasis, thoroughly recommend them for your security requirements.

Haven't had it put to test yet, but looks and feels very substantial, Thieves should have a hard time removing this.
Ordered and delivered in a couple of days.

When you look at other 'high quality' U locks on the market from the big named brands there all €100+. Anyone with a decent bolt cutters can come along snip it in silence and drag away your pride and joy. Great to see a U Lock that can finally not be snipped and only for €55? Steal

First lock that was delivered unfortunately had a fault but Steve was quick to address the issue and get a new one sent out, can't ask for much more really. The lock feels solid and has some weight behind it unlike others I've looked at.

I use this in conjunction with a front disc lock as my overnight security. Fits nicely through my rear springs and rear wheel spokes. 4 starts as the internals are prone to rust and seizing every ~6 months, so could do with some rubber seals to stop water getting in. [Pragmasis Comment: I do not know of any cases of a DIB D-Lock suffering internal rusting problems. Is it actually the DIB or the other lock that you are using that has rust problems??? Please could you get in touch with us so we can investigate? I'm sorry I can't tell who you are from "Mr. L" so I can't make contact proactively from our side. Thanks, Steve.]

Great Quality, I bought also another shackle. Thank you

Bought this to compliment a 16mm chain. works easily in use and to fit round the frame on the bike. well constructed solid function looks good with professional finish.

Great product and superb customer service, thank you very much.
