Description & Details

The Motorguard: Thieves Hate It. You'll Sleep Easy.

Your bike is a target. The DiscGuard makes sure it's not your bike they take.

🔊 The 120dB Scream That Ends Theft Instantly The second a thief touches your bike, a 120dB alarm rips through the street — loud enough to turn every head and send them running empty-handed. Most thieves bolt before they even get their tools out.

⚡ On in 2 Seconds. Off in 1. Clamp it onto your brake disc, press down, done — alarm armed instantly, no tools, no faff. A quick turn of the key and you're gone. Security that never slows you down.

🛡️ Built to Take a Beating Hardened alloy body shrugs off hammers, prying and brute force. They can hit it all they like — it won't budge, and it won't shut up.

🔋 Charge It Once, Forget It for Months A single USB-C top-up (about 70 mins) lasts 5–6 months. No fiddly batteries, no nasty surprises. IP-rated and weatherproof, rain or shine.

Fits virtually every motorbike and scooter. Slips straight into your pocket. Backed by 10,000+ UK riders who ride knowing their bike will still be there when they get back.

YOUR 7 BIGGEST CONCERNS ANSWERED

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?＋
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?＋
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?＋
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?＋
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?＋
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?＋
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!
