Best bike lock Netherlands 2026: ART certification and theft prevention
900,000+ bikes stolen per year in the Netherlands. The right locks, correctly used, are your first line of defence.
Short answer: For most expats the minimum sensible setup is an ART-2 frame lock (ringslot) plus a separate ART-2 or ART-3 chain or U-lock that lets you attach the frame to a solid fixed object. Treat a good lock as part of the bike's purchase price, not an optional extra. For broader cycling advice, see our cycling guide for expats and our cycling safety and rules guide.

How bad is bike theft in the Netherlands?
Approximately 900,000 bikes are stolen in the Netherlands every year. That works out to roughly one bike stolen every 35 seconds. The problem is concentrated in larger cities: Amsterdam, Rotterdam, Utrecht and The Hague consistently see the highest theft rates, but no city is immune.
E-bikes, fatbikes and cargo bikes have become prime targets in recent years because of their high resale value. A well-secured ordinary city bike is often passed over in favour of an expensive e-bike left with only a basic lock. That shift matters when you are deciding how much to invest in security.
A cheap second-hand bike bought for €80 with its original ring lock is effectively treated as disposable by many expats in large cities. That is a rational choice if the replacement cost is low. See our secondhand shopping guide for safe ways to buy a used bike. But a new or lightly used bike worth €400 or more, left outside with poor security, means you are self-insuring against a very likely loss.
City risk note: In big cities like Amsterdam, Rotterdam, Utrecht and The Hague, poorly secured bikes can disappear within hours even in busy areas. Thieves operate openly and quickly, often with cordless angle grinders or heavy bolt cutters.

ART certification and Dutch insurance requirements
What is the ART keurmerk?
ART (Algemeen Reglement Tweewielers) is an independent Dutch certification body that tests and certifies bike locks. Unlike a manufacturer's own security rating, ART uses standardised tests including resistance to sawing, bolt cutters, freezing, leverage attacks and lock picking. Locks that pass are awarded a star rating from 1 to 5.
| ART rating | Use case | Typical for |
|---|---|---|
| ART-1 | Basic, use as second lock only | Old bikes, low-risk areas |
| ART-2 | Standard security | Regular city bikes, insurance minimum |
| ART-3 | Heavy security | E-bikes, high-risk areas, cargo bikes |
| ART-4/5 | Motorcycle/scooter grade | Not typically needed for bicycles |
What Dutch insurers typically require
Insurance requirements vary by policy, but these are the most common patterns you will encounter:
- Normal city bike: one ART-2 lock minimum
- E-bike: two ART-2 locks, or one ART-2 plus one ART-3 chain
- High-value e-bike or cargo bike: two heavy locks, at least one ART-3 or higher
If you plan to take out a Dutch bike insurance (fietsverzekering), check the small print and buy locks that clearly meet their ART requirement before making a claim. Insurers can and do reject claims when the wrong lock was used.
The main lock types for Dutch cycling
Frame lock (ringslot)
The ringslot is the standard lock found on nearly every Dutch city bike. It fits permanently on the rear fork and inserts a bolt through the wheel spokes when closed. Many ART-2 certified models are available from AXA and ABUS.
Pros
- Always on the bike, nothing to carry
- Quick to use for short stops
- Meets the insurance "first lock" requirement
- Wide range of ART-2 certified models
Cons
- Only immobilises the rear wheel
- A thief can still lift the bike into a van
- Must be combined with a second lock for real security
Best for: Always as your base lock, and for very short stops where the bike stays in sight.
Chain lock (kettingslot)
A chain lock is the most popular second lock choice in Dutch cities. Its flexibility lets you thread it through the frame, the rear wheel and around a fixed post in one pass. ART-2 and ART-3 grades are widely available.
Pros
- Flexible (fits thick posts, crowded racks, cargo bikes)
- ART-2 and ART-3 grades available
- Hard to attack quietly with a grinder
Cons
- Heavy (2-4 kg for a good model)
- Cheap uncertified chains saw through easily
What to look for: ART-2 or ART-3 rating, 8-10mm or thicker chain links, 100-140cm length (140-170cm for cargo bikes).
Best for: City use near stations, e-bikes left outside overnight, anywhere with wide or irregular posts.

A U-lock offers excellent bolt cutter resistance in a lighter package than a comparable chain. The rigid shackle means less movement for an attacker to use, which improves security against leverage tools.
Pros
- Very strong against bolt cutters
- Lighter than an equivalent chain
- Compact and easy to carry on the bike
Cons
- Less flexible than a chain lock
- Some Dutch posts and racks are too wide for the shackle
Best for: Pairing with a frame lock at standard racks, high-value bikes parked at regular spots where you know the infrastructure fits.

Folding locks use a series of rigid steel segments connected by rivets. They fold down compactly for carrying but extend to provide flexible coverage, sitting between a U-lock and a chain in terms of flexibility.
Pros
- More flexible than a U-lock
- More compact than a chain when folded
- Some models are ART-2 certified
Cons
- Rivets can be a weak point on cheaper models
- Often pricier per security level than a chain
Best for: Commuters who want compact but reasonably strong security and prefer not to carry a heavy chain.

Several brands now offer smart locks with app connectivity, and GPS trackers designed to hide inside a bike tube or saddle are increasingly popular. These tools can help police locate a stolen bike after the fact, and some insurers offer premium discounts for them.
However, insurers still only accept ART certification and correct locking technique for any theft claim. A GPS tracker does not physically prevent theft. Use trackers as a useful bonus layer, not as a substitute for proper ART-certified locks.

Use this as a starting point and adjust for your neighbourhood and parking habits. Riders in Amsterdam or Rotterdam should treat each tier as a minimum, not a target.
| Situation | Minimum setup | Budget (locks only) |
|---|---|---|
| Cheap city bike (up to €250), smaller town, mostly daytime use | 1x ART-2 frame lock + 1x ART-1 or ART-2 chain (short) | ~€40-70 |
| Standard city bike (~€300-700) in a big city | 1x ART-2 frame lock + 1x ART-2 chain or U-lock through frame, rear wheel and around fixed object | ~€70-120 |
| New e-bike (€2,000 or more), regularly parked outside | ART-2 frame lock + heavy ART-3 chain around frame and fixed object; remove battery when parked long term | ~€120-200 |
| Cargo bike / bakfiets, often outside overnight | ART-2 or ART-3 frame lock + long ART-3 chain (150-170cm) to fixed anchor; optional wall or ground anchor at home | ~€150-250 |

Where to buy bike locks as an expat
Local bike shops (fietsenwinkel)
A local bike shop is the best starting point if you are new to Dutch cycling. Staff understand insurance requirements, can recommend the right ART level for your situation, and can mount a frame lock for you on the spot. Prices are slightly higher than online, but the fitting service and advice are worth it for a first purchase.
Large retail chains
Decathlon, Halfords, Hema and Blokker all stock ART-approved locks at reasonable prices. Selection is narrower than online, and not all staff can explain insurance implications in detail. Always check the ART logo yourself before buying, as labelling on packaging can vary.
Online (bol.com and Amazon.nl)
Online shopping gives you the widest range of certified locks at the best prices, with delivery to your door often the next day. The main risk is misleading product listings: some sellers claim high security ratings that are not backed by actual ART certification. Always verify the ART logo and star rating in the product listing before buying.

How to lock your bike correctly
Good locks only work when used correctly. Many theft claims are rejected not because the wrong lock was used, but because the bike was not secured properly. Follow these steps every time you park.
- 1
Always close the frame lock first. Never leave a parked bike with only a chain and the frame lock open.
- 2
Pass your chain or U-lock through the frame AND at least one wheel, preferably the rear wheel which is more expensive to replace.
- 3
Attach to something solid: a proper metal rack anchored in the ground, not a thin signpost, a low fence, or something that could be lifted over.
- 4
Keep the lock body off the ground. Bolt cutter and angle grinder attacks are easier when the lock rests on the pavement and cannot swing.
- 5
Fill the interior space of a U-lock as much as possible. A tight fit leaves less room for a crowbar and reduces the leverage an attacker can apply.
Additional rules for e-bikes and cargo bikes
- Remove the battery and display panel when parking for more than a few minutes in a public place
- Consider a wall or ground anchor at home for overnight storage
- Avoid leaving high-value bikes outside overnight near train stations or city-centre nightlife areas where tools are in regular use by thieves
Common expat mistakes with bike security
Using only the original ring lock from a cheap second-hand bike in Amsterdam
Fix: Add an ART-2 chain lock and always attach the bike to a solid fixed object. A ring lock alone is not enough in any major Dutch city. Our cycling guide covers what to look for when buying a second-hand bike.
Buying an expensive e-bike without upgrading locks at the same time
Fix: Budget 5-10% of the bike's value for security when you buy it. That means locks, possibly a ground anchor for home storage, and fietsverzekering.
Ignoring the ART logo and buying based on looks or online star ratings
Fix: Always verify the ART-2 or ART-3 mark on the packaging or product listing. Marketing claims and customer review stars do not indicate ART certification.
Locking only the front wheel to a rack
Fix: Thieves detach the front wheel and take the rest of the bike. Always lock through the frame. If your chain is long enough, include a wheel as well.
Not recording the frame number and not keeping photos of the bike and locks
Fix: Photograph the bike, note the frame number (found on the bottom bracket or down tube), and keep receipts for your locks. Insurers and police need this information if the bike is stolen.
Bike locks and Dutch insurance (fietsverzekering)
Dutch bike insurance policies are specific about lock requirements. A claim can be rejected entirely if you did not use the right lock, cannot produce both keys, or did not attach the bike to a fixed object when the policy required it.
Home contents insurance (inboedelverzekering) generally does not cover a bike stolen from the street, a parking garage, or anywhere outside your home. If you want theft cover for your bike, you need a separate fietsverzekering. When budgeting for your full move setup, our relocation budget guide covers bike costs alongside all other first-month expenses.
For expensive bikes, the combination of ART-certified locks used correctly, plus a dedicated fietsverzekering, is the only reliable protection. Locks reduce the chance of theft; insurance covers you financially if theft occurs despite good locks.
Insurance tip: For e-bikes and cargo bikes, keep receipts for all locks as well as the bike itself. If you claim for theft, insurers may ask for proof of purchase of the locks to confirm they met the required ART level.

Frequently asked questions about bike locks in the Netherlands
Do I really need two locks in the Netherlands?
For bikes you care about in any larger city, yes. Dutch cyclists and insurers strongly advise a frame lock (ringslot) plus a second lock, a chain or U-lock that secures the frame to a fixed object. A frame lock alone only immobilises the rear wheel; a thief can still lift the bike into a van. For a cheap second-hand bike in a small town you might accept the risk with one good lock, but for anything valuable, two locks are the standard.
What does ART certification mean for bike locks?
ART (Algemeen Reglement Tweewielers) is an independent Dutch certification system. Locks are tested for resistance to sawing, bolt cutters, freezing, leverage and lock picking. ART-1 is basic (use as a second lock only). ART-2 is standard for regular city bikes and meets most insurance requirements. ART-3 is heavier security, often required by insurers for e-bikes. Always look for the ART logo and star rating on the lock packaging.
Is a chain lock or U-lock better for Dutch cities?
Both work, but a chain lock (kettingslot) is often more practical in Dutch cities because it is flexible enough to go around thick lamp posts, crowded racks and wide cargo bikes. A U-lock is lighter for its strength and works well if you always park at standard bike racks. Many long-term Dutch residents prefer a heavy ART-2 or ART-3 chain because Dutch street infrastructure, wide posts, chaotic racks, can make U-locks awkward to use.
What locks does my bike insurance require in the Netherlands?
Requirements vary by insurer and policy, but typical patterns are: one ART-2 lock for a regular city bike, two ART-2 locks or one ART-2 plus an ART-3 chain for an e-bike, and two heavy locks (one ART-3 or above) for a high-value e-bike or cargo bike. You must also lock the bike correctly and be able to produce both keys if you claim. Always read the small print of your fietsverzekering (bike insurance) before buying locks.
How much should I spend on bike locks compared to the bike price?
A practical Dutch rule of thumb: spend €40-70 on locks for a basic city bike, €70-120 for a standard city bike worth €300-700, and €120-200 for an e-bike or cargo bike. If that seems high, compare it to the cost of replacing the bike. Budget for locks when you buy the bike, not after.
Can I rely on a GPS tracker instead of ART locks?
No. GPS trackers help with recovery after theft and may qualify for insurance extras, but they do not stop a thief from physically taking your bike. Dutch insurers still require ART-certified locks and correct locking technique for any theft claim. Treat trackers as a useful bonus layer on top of proper locks, not as a replacement.
Where should I buy bike locks in the Netherlands?
Local bike shops (fietsenwinkel) give the best advice and can mount frame locks for you. Large retailers like Decathlon, Halfords and Hema carry ART-approved models at reasonable prices. Online via bol.com or Amazon.nl you get the widest range and often the best prices, but always verify the ART logo and star rating in the product listing, as some listings exaggerate security without having ART certification.
How do I lock my bike correctly in the Netherlands?
Always close the frame lock first. Then pass your chain or U-lock through the frame and at least one wheel, and attach it to a solid fixed object (a proper metal rack, not a thin signpost or low fence). Keep the lock body off the ground so it cannot be attacked with bolt cutters on the pavement. For U-locks, fill as much of the interior space as possible to reduce leverage. For e-bikes, also remove the battery and display when parking for longer periods.
What happens if my bike is stolen and I did not use the right lock?
Your insurance claim can be rejected. Insurers commonly reject theft claims when: the lock used did not meet the ART requirement in the policy, the rider cannot produce both keys for each required lock, or the bike was not locked to a fixed object when the policy required it. Home contents insurance (inboedelverzekering) generally does not cover a bike stolen outside your home. You need a separate fietsverzekering for that.
