TufLuck review | Highly secure ground anchor destruction tested

Date reviewed: October 2025 | Tested by: John Milbank | Price: £599.99 (£509.99 for first 30) | Weight: 35.4kg | tufluck.co.uk

The TufLuck on review here is an incredibly solid ground anchor that secures the front wheel of almost any bike, protecting all the potential attack points with thick steel and a hardened locking pin.

Designed by Milton Keynes-based Kozomos Kalman, who came up with the Squire Atilla – the first ever Sold Secure Diamond-rated motorcycle disc lock –  Kal has refined the design of the Tufluk over months of testing with various bikes, and it’s being made entirely in the UK (only the Federal S401 lock is brought in from overseas).

Bennetts BikeSocial tested a very late pre-production version of the TufLuck and gave feedback from the testing for some minor changes that will go into the retail versions that are on sale now. The first 30 orders will be priced at £509.99, with the full retail price being £599.99. Shipping costs an additional £55 due to the size and weight.

Pros & Cons

Size and weight

Weighing over 35kg, the TufLuck is the heaviest security device I’ve ever tested. The body is made of 6mm-thick steel, with cleverly-positioned protection panels that make access with an angle-grinder impossible (which is why I also tested a reciprocating saw attack).

The TufLuck shown in this review is a pre-production model – after feedback from our testing the retail versions are around 40mm taller at the top to further restrict access with a reciprocating saw (despite this not being part of the Sold Secure Powered Cycle Diamond test), along with some other tweaks including an extended locking pin protector.

The case- and through-hardened locking pin measures 25mm in diameter, and the Federal S401 padlock has a fully-enclosed shackle with a hardened steel body and a 6-pin anti-bump, anti-drill barrel with two keys supplied. 

Fitting a huge range of wheels, the TufLuck will accommodate disks that are a maximum of 160mm apart, which meant that my 2019 BMW R1250GS, 2001 Honda VFR800 and 1999 Kawasaki ZX-6R all fitted no problem at all.

Getting your bike in and out can take a little bit of practice but you soon get used to it. Heavier machines can require a bit of a pull to release from the wheel cup, but again it’s something that just takes a few goes.

The cup on the base rotates to hug the wheel and can be adjusted through a range of 11 holes to suit the bike. In my testing I had no issue getting the locking pin through except with the tightly-packed spokes of the GS, which needed a bit of jiggling to find the best position. A slightly longer locking pin could make this easier by allowing it to sit at an angle, without there being any reduction in the very high level of protection offered.

Five M10 expanding bolts are supplied to fix the TufLuck to the ground, but with 10 holes you could go even further if you wanted to. Not that there’s much need – there’s no way this is going to be broken free unless it’s very poorly installed.

Do take your time finding the best position for the TufLuck, and make sure you can get easy access to the locking bar before fixing it down, but if you did decide to relocate it at some point, the bolts are removable when the bike’s taken out. To prevent anyone else removing the TufLuck, the locking bar can be secured through the bottom hole, preventing access to the fixing bolts when you’re out on the bike.

Resistance to attack: lock picking

While some YouTube channels might make lock picking look easy, especially when selling the creator’s own tools, it’s not a theft method used in typical motorcycle thefts at all, and access to the TufLuck’s keyway is very limited.

Resistance to attack: drill

The only potential vulnerability to a drill attack on the TufLuck is the lock’s keyway, but access is extremely limited. The lock’s designed to be drill-resistant, and a sustained attack didn’t get me even close to penetrating the barrel.

Resistance to attack: lump & sledge hammer

The 6mm-thick steel construction means even a sledge-hammer attack is pointless on the TufLuck – only cosmetic damage is apparent, with no advantages before or after cutting attacks.

The TufLuck is strategically welded throughout, with a slotted assembly that means even a sustained sledge hammer attack will not weaken the welds.

Resistance to attack: reciprocating saw

While reciprocating saws are not typically being used in motorcycle thefts (hence why they don’t form part of Sold Secure’s attack testing), I used one with a quality carbide-tipped blade and found that it just skips over the surface of the locking pin that will be fitted to the production versions. It’s also slow going on the steel body.

The first version of the locking pin I tested did eventually succumb to this attack, but after discussing the results with Kal he sent a new pin for testing using a different hardening. This took a lot of work in a vice before I could get through it, and the retail versions will be case-hardened twice as deep, so even more resistant.

With the 40mm extra height coming on the TufLuck’s body, a reciprocating saw won’t even reach the pin now, so combined with the harder pin this is not in any way a viable attack method.

Resistance to attack: angle-grinder

This section is usually where I state that – at best – it took a lot of work to defeat the device with an angle-grinder. However, in the case of the TufLuck I had to give up.

The TufLuck’s locking pin is completely inaccessible to an angle-grinder once the bike’s in place. The only way to get at it would be to cut one of the side plates off to get at either end of the pin.

Though the 6mm-thick steel isn’t hardened it doesn’t need to be due to the sheer amount of it used in the design. Attempting to cut the sides off is incredibly time-consuming, and even cutting slots then hammering it doesn’t help.

Given enough time and space, the TufLuck could eventually be cut apart, but this is the first device that – even with ideal conditions – I gave up trying to defeat.

TufLuck review: Verdict

While a very unlikely attack method, some locks leave the possibility of unbolting the front or rear wheel of your motorcycle to free it. That’s not the case with the TufLuck, which completely covers your bike’s wheel and lower forks, making it impossible to remove. The only way to get your bike out of the TufLuck without the key is to disassemble the front-end of the motorcycle or spend a very, very long time cutting it off.

Nothing is completely undefeatable, but the TufLuck comes closer than anything I’ve tested before. Once your bike’s in the TufLuck, it’s not coming out.
