I Bought & Tested the Best-Selling Ebike Locks. Here's Why VaultFold is #1:
Written by Jake Thornton
After the theft, I spent two weeks scouring cyclist forums and hardware store aisles looking for something that actually worked, not just something with a tough-looking sticker on the box. I wasn't going to trust another lock without putting it through hell first.
I tried a heavy-duty chain lock next, but at nearly nine pounds it was miserable on a 12-mile commute, so it stayed home more than it stayed on my bike. Then a bargain U-lock that looked nearly identical to premium brands online — a hardware store employee talked me out of buying a second one after showing me how a car jack popped it open in under a minute.
That's when I decided to stop guessing and start testing methodically, sourcing five of the most talked-about ebike locks on the market and putting each one through the same battery of attacks, weather exposure, and daily-carry scenarios over six weeks.
Here's what I found.
My Test Results
For six weeks, I mounted each lock on my own ebike and used it exactly as a commuter would — locking up outside grocery stores, train platforms, and my apartment's outdoor rack overnight, rain or shine. I also ran dedicated attack sessions using bolt cutters, a car jack, a hand drill, and a cordless angle grinder to simulate real theft attempts.
I scored each lock across four categories: theft resistance, portability and mounting, weather resistance, and value for money. Every lock faced the identical attack sequence and the same six-week outdoor exposure period, and I cross-referenced results against published Sold Secure and ART ratings where available.
The biggest surprise was how much variance existed between locks that looked similarly tough on paper. VaultFold's hardened alloy links shrugged off two full minutes of continuous angle grinder contact before the grinder wheel showed more wear than the lock — a result I didn't expect from something that folds down small enough for a jacket pocket.
I also tracked how each lock held up through six weeks of exposure on an outdoor rack through rain and a couple of frosty mornings. The rotating head and dust cover on our top pick kept the mechanism turning smoothly the entire time, while two competitors started sticking and needed lubricant by week four.
Not every lock held up. The lighter, cheaper options in the group folded under sustained bolt cutter pressure in under 90 seconds, and one chain lock's nylon cover started fraying within three weeks of daily use. None of these were catastrophic alone, but combined they told a clear story about where corners get cut.
The Results:
Every result pointed to the same conclusion: VaultFold earns its spot as the lock I now trust with my own bike every single day.
Value
Since switching to VaultFold, I've stopped paying for the extra insurance riders my policy required for unrated locks, and I no longer waste Saturday mornings driving to the hardware store for another backup cable lock. That alone reclaimed hours I used to lose replacing gear that failed me.
Every month you ride with a subpar lock is a month you're gambling with a bike that likely cost more than a used car down payment. Cheap locks get replaced every year or two after thieves defeat them or they simply seize up, and that cycle of buying, failing, and rebuying adds up fast in time and hassle.
Its alloy construction showed zero corrosion after six weeks of exposure testing, and the included multi-year warranty outpaces what most budget lock makers offer. Given how it performed against tools that dispatch cheaper locks in seconds, this is the kind of purchase you make once and stop thinking about.
Riding (and Parking) With Confidence
These days I lock up outside the grocery store, the gym, or my kid's school without that familiar knot in my stomach. It folds down small enough to live permanently in my pannier, so I'm never tempted to skip locking up "just this once" because carrying a lock feels like a hassle.
It's not just commuters who benefit — delivery riders leaving bikes unattended for hours, parents securing a teenager's first ebike, and weekend trail riders locking up at trailheads all face the same theft risk. A lock this portable and this tough earns its place in anyone's daily routine.
Customer Reviews
"After my second bike was stolen in two years, I wasn't taking chances. It's been on my ebike for four months now, parked outside coffee shops and train stations, and it's still there every time."
"I ride an ebike for delivery work, so it's outside unattended for hours at a time. It folds small enough to stash under my seat, and I've never once worried about it not being there when my shift ends."
"Bought this for my son's ecommuter after he had a close call with someone cutting his old cable lock in under 10 seconds flat. Three months later, zero issues, and I finally sleep easier."
Frequently Asked Questions
Folding locks made from heat-treated hardened steel currently offer the best balance of security and portability for ebikes. Look for models with Sold Secure Silver or Gold ratings, double-locking mechanisms, and links thick enough to resist bolt cutters and angle grinders.
No, standard cable locks are not adequate for an ebike's value. In our testing, basic cables were defeated with hand tools in under 30 seconds, making them better suited as a secondary deterrent than a primary lock.
Using two different lock types, such as a folding lock plus a cable for the wheels, forces thieves to carry multiple tools and significantly increases the time and noise required to steal your bike.
Most riders find one high-security lock sufficient for daily use, reserving a second lock for high-risk overnight parking.
Given enough time, most locks can eventually be defeated by a powerful angle grinder. The goal is choosing a lock tough enough to take several minutes rather than seconds, since thieves rarely risk the noise and attention that longer attempts attract.
Yes, moisture and freezing temperatures can cause cheaper cylinders to jam or corrode over time. During our six-week outdoor testing period, locks with dust covers and weatherproof coatings kept working smoothly, while a couple of budget models needed lubrication by week four.
Pricing varies by security tier rather than a fixed number, but generally you get what you pay for. Mid-range and premium locks with verified security certifications cost more upfront but save you from the far greater expense of losing your ebike entirely.
VaultFold combines heat-treated alloy construction with a 360° rotating lock head and dust-proof cover, a combination that helped it outlast every other folding lock in our six-week test. It's also light enough to carry daily without the bulk of a chain lock.
Absolutely. A strong warranty signals the manufacturer's confidence in their materials, and some brands even offer replacement guarantees if your bike is stolen while properly secured. It's one more reason models like VaultFold stand out from bargain alternatives.
Purchase and Delivery Process
Ordering VaultFold is refreshingly simple since it's sold directly online, which cuts out retail markups you'd pay at a bike shop. I'll be honest though — when I first tried to order a second one as a gift, it was sold out, and I ended up waiting almost two weeks for the next restock.
Demand has clearly outpaced supply since this lock started getting attention, so if you see it in stock, I'd grab it before it disappears again. Once your order goes through, shipping has been fast in my experience, typically arriving within about a week.
