A foldable hardened-steel lock buys real extra minutes against a grinder — unlike a cable cut in seconds, a U-lock gone in a minute, or an alarm everyone ignores.
- Hardened steel that costs a thief real time and tools — not seconds.
- Folds flat to pocket-size. No dead weight on your frame all day.
- Mount bracket + 3 keys included — locking up stays a 5-second habit.
- Layer it with your current lock — two LockdUps beats one lock and hope.
Will this actually survive an angle grinder?
No lock does — not even $380 ones, per independent testing. LockdUp is built to cost a thief real time and noise, not to be indestructible.
Is one lock enough, or do I need to layer?
Most security-minded riders layer two — wheel and frame, or home and work. That's why LockdUp comes in a Duo.
Does this meet what my insurer requires?
We can't promise that — LockdUp doesn't currently carry a Sold Secure or equivalent certification. If your policy requires a rated lock, use LockdUp alongside it, not instead of it.
Sound familiar?
Two minutes outside the shop, same as always. But you've seen the videos: a battery grinder takes thirty seconds on the wrong lock. Now you glance back before you reach the door. That flinch is new.
Why the lock you already own isn't enough
- Cable locks. It made sense — light, cheap, easy to carry daily. But riders call them useless, worthless, done: cut in seconds.Traced: forum users tobsters, joebristol, cynic-al, dirk_pumpa
- Cheap or "premium" U-locks. It made sense — a U-lock feels like a real lock. But even Kryptonite-grade steel goes in about a minute to a battery grinder.Traced: Smaug, Kingfisher101, ebikegeek.co.uk
- Alarm-only disc locks. It made sense — a loud alarm feels like backup. But bystanders hear alarms and keep walking. Nobody actually comes.Traced: forum users flecc, BazP
- Even premium D/U-locks alone. It made sense to spend big on the "best" lock. But independent testing shows even £250+ locks fall to 1–3 grinder discs within 5 minutes.Traced: Cycling Weekly, 2026
The real problem
Thieves didn't get smarter — they got better tools. A battery grinder is cheap, cordless, and bag-sized. Most locks, even respected ones, were rated before that became street kit. You didn't buy badly; the threat moved and your lock didn't.
The solution
The fix isn't a louder alarm — it's steel that costs real time, tools and noise to cut. LockdUp is a folding hardened-steel lock that still folds flat enough to carry daily, built to turn a thirty-second job into several loud minutes — long enough that most thieves walk away.

How it actually works
Thin metal, cut in seconds by a battery grinder.
Hardened steel resists the same cut for minutes, not seconds.
Fold it flat, mount it, carry it every ride.
More time and noise than most thieves will risk.

Built from hardened steel
Six hardened-steel plates on riveted joints — folding hardened-steel locks sit closer to the independently tested category (Cycling Weekly, 2026) than a thin disc-lock pin ever did. Hardened steel, mount bracket and 3 keys in every pack.
LockdUp vs. the failed category
| Time / effort to defeat | |
|---|---|
| Cable lock | Seconds |
| Cheap or premium-brand U-lock | ~30–60 seconds |
| Disc-lock-alarm | Alarm sounds, thief still leaves |
| £250–380 premium D/U-lock | 1–3 discs / 5 minutes |
| LockdUp folding hardened-steel lock | Designed to add real minutes, not seconds |

More questions
Will an alarm scare a thief off?
LockdUp has none. Bystanders mostly ignore bike alarms, so we put that cost into steel instead of a speaker.
Is a folding lock as strong as a solid U-lock?
Folding locks are a little more vulnerable at the hinges than a one-piece shackle. We say so upfront.
Will I forget it's on the bike?
It folds flat and mounts visibly on the frame, so it stays part of your normal locking habit.
Is this worth it next to my £100+ main lock?
It's a smaller add-on spend for a second, independent layer — not a replacement purchase.
How long does delivery take?
Shipping cost and delivery time are shown at checkout. UK orders also carry a 30-day right to cancel.
What if I want to return it?
Our 90-day money-back guarantee, on top of your 30-day UK right to cancel.
Does it hold up outdoors?
It's built weather-resistant. An outdoor-exposure test is running before we claim more — see the Honest Box below.
This product is NOT:
- A replacement for a certified Sold-Secure-rated lock — pair it with one if your insurer requires that rating.
- Fully theft-proof. No lock is, including locks costing 4–6x more.
- As rigid at the hinge as a solid shackle — a disclosed folding tradeoff.
- Independently lab-tested for grinder resistance on this unit — planned, not done.
- Sold with an alarm. If you want an audible deterrent, look elsewhere.
Your lock was built for a thief without a battery grinder. LockdUp is built for the one who has one — hardened steel, mount bracket, 3 keys, 90-day guarantee. No alarm to ignore. Just more time between your bike and gone.
