"Honestly didn't think a disc lock could be this loud. Some idiot tried to wheel my bike off the drive and the alarm went off like a fire engine. Woke up half the street, woke up me, and by the time I got to the window he was already three gardens down. Fits my Yamaha perfectly."

I do the food delivery rounds on my scooter and I'm on and off it fifty times a night. Clips on in seconds and lives in my jacket pocket. Cheap insurance really. Two of the other lads at the depot have bought one since they saw mine.

"Bought this after a mate lost his bike to an angle grinder gang. Was skeptical, thought it'd be flimsy for the money, but it's a proper solid bit of kit. Weighs a fair bit in the hand which is exactly what you want. Rains constantly up here and it hasn't rusted or played up once."

🔧 How To Use
🔧 How To Use
Locked & Loaded in Under 10 Seconds
No manual needed. No tools. If you can clip a keyring, you can use the DiscGuard.
1️⃣ Clamp It On Slot the DiscGuard onto your brake disc, lining the pin up with one of the holes. Push it firmly until it clicks shut.
2️⃣ Press to Arm Press down to lock — the alarm arms itself instantly. That's it. Your bike is now guarded 24/7 and the lock can't be removed without the key.
3️⃣ Attach the Hi-Vis Reminder Loop the bright cable from the lock to your handlebar. A simple reminder that saves you from riding off with it still on.
4️⃣ Ride Off Worry-Free When you're back, just insert your key, turn, and lift it off. Disarmed and pocketed in one second flat.
💡 Pro Tip: Fit it to the front disc where it's most visible — the brighter and more obvious your lock, the faster a thief moves on to an easier target.

YOUR 7 BIGGEST CONCERNS ANSWERED
Will this fit my motorbike or scooter?
Will this fit my motorbike or scooter?
Yes, the DiscGuard fits virtually every motorbike and scooter on UK roads, from 125cc commuters to full-blown superbikes. The locking pin is sized to fit the standard holes on almost any brake disc. It takes 10 seconds to check: if your brake disc has holes (nearly all do), you're sorted. Still unsure? Email support@trylockt.com with your bike model and we'll confirm for you.
How quickly can I get it on and off?
How quickly can I get it on and off?
Armed in under 10 seconds, off in one. No complicated setup, no instruction manual needed. Clamp it onto your brake disc, press down to lock, and the alarm arms itself instantly. A quick turn of the key and you're gone. Simple enough to use every single time you park, but tough enough to stop thieves in their tracks.
Can thieves actually break through this?
Can thieves actually break through this?
The DiscGuard's hardened alloy body is engineered to resist hammers, pry bars and brute force. But its real weapon is the noise: the moment anyone touches your bike, a 120dB alarm screams the whole street awake. No security is 100% invincible, but here's the reality of UK bike crime — thieves want quiet, easy targets. A lock that's impossible to break silently and screams the second they try? They move straight on to the next bike. It's your first and loudest line of defence.
Won't the alarm go off by accident?
Won't the alarm go off by accident?
No. The DiscGuard uses a smart shock sensor: light vibration triggers 3 short warning beeps first, so a passing lorry or a nudge won't set off the full siren. Only genuine tampering escalates it to the full 120dB alarm for 15 seconds. Clever enough to know the difference between the wind and a thief.
How long does the battery last?
How long does the battery last?
Charge it once with the included USB-C cable (about 70 minutes) and it runs for 5–6 months on a single charge. No fiddly batteries to hunt down or replace. A low-battery indicator gives you plenty of warning before it needs a top-up — plug it in overnight and forget about it.
What if I lose the keys?
What if I lose the keys?
You get 2 keys with every order — keep one on your keyring and one somewhere safe at home. Lost them both? Like any high-security device, you'd need a locksmith. But honestly, most riders are very careful with the keys that protect a bike worth thousands.
What if it doesn't work for my setup?
What if it doesn't work for my setup?
Zero risk to try it. Our 90-Day Peace of Mind Guarantee means you can test it properly on your own bike. Doesn't fit? Changed your mind? Email support@trylockt.com and we'll process your full refund, no interrogation. But honestly? Most riders don't send them back — they usually come back to buy a second one for their partner's bike.

Living in Birmingham, you're basically asking for it without proper security. Saw two lads on my Ring doorbell at 3am eyeing up the bikes on my street. The second one gave mine a nudge, the DiscGuard went off like a car alarm on steroids, 3am and the whole street lit up. They properly legged it and didn't come back. Best investment I've made all year.

"After my mate's MT-07 got nicked off his drive last week (two lads, angle grinder, gone in under a minute), I wasn't taking any chances. Ordered this straight away. Takes literally 10 seconds to pop on and the alarm arms itself. I actually sleep soundly now knowing that if anyone so much as touches it, the whole street's going to hear about it. If you park your bike outside, you need this.

Our street WhatsApp group has been mental lately with all the bike thefts round here, feels like every week someone's had theirs nicked. Bought a DiscGuard and honestly, half the lads on the street have followed suit now. The road next to us got hit again last night, but ours were all untouched. Thieves want an easy ride, don't give them one!

Fits my Yam FZ25 perfectly, slots right onto the disc no bother. And it's loud, tested it in the garage and it properly screams. Happy with it.
Bought this after a mate had his bike pinched. Well made, feels solid, and it fits my Street Triple spot on. Does exactly what it's meant to..
Decent bit of kit for the money. Alarm's loud and the build feels sturdy. Only knocked a star off because the instructions were a bit brief, but figured it out fine
Fits my MT-07 like it was made for it. No wobble, clamps on tight. Chuffed with it to be honest.
Ordered it, turned up quick, fits my CB500X no problem at all. Alarm's proper loud and it's small enough to actually carry about. Can't complain.
Been using it a couple months now on my GS. Fits perfectly, still on the first charge, and it's survived a fair bit of rain already. Sound product.
Good lock. Fits my Ninja 650 nicely and the alarm's no joke. Would've liked it in a couple more colours but that's just me being picky. Does the job well.
Fits my bike perfectly and it's dead easy to get on and off. That was my main worry ordering online but no issues at all. Quality's better than I expected.
Honestly a well thought out bit of gear, alarm's loud enough to wake the street, and it's small enough that I actually take it with me. That was always my problem before.
Does what it says. Fits my Bonneville nicely, feels well built, and the free lanyard's a handy touch so you don't ride off with it on. Solid buy.
