Imagine this: you’ve just invested in a sleek, $2,000 electric bike that makes your daily commute faster, cheaper, and way more fun. One day, you lock it up for a quick stop—just 10 minutes. You return, and it’s gone.
Why E-Bikes Need Special Security
Electric bikes are like candy to bike thieves—more valuable, more desirable, and often less protected. Standard bike locks just don’t cut it anymore. Here’s why e-bikes need an extra layer of security:
- Higher Value = Higher Risk: E-bikes can cost 2–3x more than regular bikes, making them prime targets.
- Heavier Frames: A thin cable lock won’t hold up against bolt cutters, and your e-bike isn’t easy to carry indoors.
- Longer Parked Times: Commuters and delivery riders often leave bikes unattended for hours.
That’s where heavy-duty chain locks come in. But not all chains are created equal.
What Makes a Chain Lock “Secure”?
Not all locks marketed as “strong” are truly theft-resistant. To help you shop smart, here are the key factors to consider:
1. Material Strength
Look for hardened steel chains—preferably manganese or boron steel. These are much more resistant to bolt cutters and saws.
2. Thickness of the Chain
You want something in the 9mm–14mm range. Anything below 8mm can be snipped in seconds.
3. Lock Mechanism
The lock cylinder should be pick- and drill-resistant. Bonus if it’s tested against angle grinders.
4. Length and Flexibility
Longer chains (90–120cm) give you more options to lock your bike to immovable objects like poles or fences.
5. Weight
Security often means added weight. Expect 2–5kg for a proper chain lock. It’s a tradeoff—but one that could save your e-bike.

How to Use Your Chain Lock for Maximum Protection
Even the strongest lock won’t help if used carelessly. Here’s how to lock your e-bike properly every time:
- Lock to something immovable: No fence posts that can be lifted or street signs that are loose.
- Go through the frame and rear wheel: Just locking a wheel is an invitation for theft.
- Keep the lock off the ground: Makes it harder for thieves to hammer or leverage it.
- Use two locks if possible: Pair a chain with a U-lock or folding lock to protect both wheels.

Real-World Scenario: James in Brooklyn
James is a delivery rider in NYC using a $3,000 Aventon e-bike. After his first bike got stolen in broad daylight—even with a U-lock—he upgraded to a Kryptonite chain lock. “It’s heavy, sure, but I sleep better,” he says. He now locks his bike through the frame and rear wheel, and always checks for sturdy anchor points. So far: no thefts, even during 10-hour shifts.
FAQs: Everything You Need to Know
Can a chain lock be cut?
Yes—if it’s cheap or thin. A quality 10–14mm hardened steel chain will resist bolt cutters and grinders much longer.
Is a chain lock better than a U-lock?
Chain locks offer more flexibility, especially for awkward lock-up spots. But for max protection, use both.
How heavy are secure chain locks?
Expect 2–5kg. Some brands now offer wearable options (e.g., Hiplok) to ease the burden.
Do I need insurance if I have a chain lock?
Absolutely. A good lock reduces risk, but insurance protects your wallet if something goes wrong.
