Cargo bike locks and theft protection
What your insurer actually requires
The most common reason cargo bike insurance claims get denied isn't fraud. It isn't a technicality in the small print. It's the wrong lock. Or the right lock used the wrong way.
This guide covers the certification standards insurers require across Europe and the UK, the specific locks that meet them, and the compliance rules that can void your claim even if you did everything else right.
The three certification bodies
Sold Secure (UK-based, recognised across Europe)
The dominant standard in the UK and increasingly used by pan-European providers like Laka. Four levels:
- Bronze: Opportunist theft. Up to ~£250/€300.
- Silver: Determined thief. Up to ~£1,500/€1,700.
- Gold: The minimum for cargo bikes. Required for bikes over £1,500/€1,700.
- Diamond: Maximum protection. Often mandated for bikes over £5,000/€5,500.
In 2024, Sold Secure introduced a separate Powered Cycle category with testing against portable angle grinders. For e-cargo bikes, look specifically for Powered Cycle Gold or Diamond.
ART Foundation (Netherlands/Belgium)
- ART-2: Baseline for e-bikes and cargo bikes. 60cm bolt cutters.
- ART-3: Moped-grade. 90cm bolt cutters. Often required for bikes over €4,500.
- ART-4: Light motorcycle grade. Required by some Belgian insurers for premium cargo bikes.
VdS (Germany)
- VdS Class A: Standard bicycle security.
- VdS Class A+: For securing to a fixed object. The standard for cargo bikes.

The four rules that void your claim
These are not edge cases. These are the most common reasons cargo bike theft claims get denied.
1. The immovable object rule
Almost every policy requires the bike to be secured through the frame to a permanent, solid fixture. A frame lock alone is not enough. A chain wrapped around the bike itself is not enough. The lock must physically connect the bike to something that cannot be moved.
If your insurer asks "was the bike angeschlossen or abgeschlossen?" and the answer is only abgeschlossen (locked to itself), the claim is denied.
2. The two-lock mandate
For cargo bikes parked overnight in urban hotspots, insurers like Kingpolis, Laka, and several German providers require two separate locks. One through the frame to a fixed object, one through a wheel. Both must meet the minimum certification. Increasingly common for bikes over €4,500/£4,000.
3. The price floor
In Germany, some insurers specify a minimum lock purchase price, typically €50 or 10% of the bike's value, regardless of certification. A €15 lock with an ART-2 sticker won't cut it. Keep your lock receipt.
4. GPS as a mandatory requirement
For e-cargo bikes over €4,500/£5,000, some providers now make an active GPS tracker mandatory for theft coverage. Not optional. Not a discount. A requirement. Kingpolis (Belgium) and BackPedal (UK) lead this trend.
Even where not mandatory: Qover offers 20% discount. Recovery rates: ~80% with GPS vs ~15% without.
How to lock a cargo bike properly
The minimum setup:
- One certified lock (Sold Secure Gold / ART-2 / VdS A+ / Varefakta minimum)
- Through the frame (not just a wheel)
- To an immovable object
For bikes over €4,500:
- Two certified locks
- One through the frame, one through a wheel
- GPS tracker active
Cargo bikes often don't fit into standard bike rack slots. Look for U-shaped racks, Sheffield stands, or posts with enough clearance. Never lock only through a wheel. A wheel can be removed in 30 seconds.
GPS tracking
If your bike has integrated GPS (Bosch Connect, Gazelle Connect, Tern with Bosch Smart System), make sure it's activated and the subscription is current. Read our full GPS tracker guide for aftermarket options, insurance requirements, and 5-year cost comparisons.
- ~15% recovery rate for registered bikes without GPS
- ~80% recovery rate with active GPS tracking
- 20% premium discount from Qover for GPS-tracked bikes
- Mandatory GPS for bikes over €4,500 with Kingpolis (Belgium)

A €100 lock protecting a €6,000 bike is not a cost. It's the cheapest insurance premium you'll ever pay. And if you buy the wrong one, or use the right one the wrong way, your actual insurance won't pay out.
Buy the lock your insurer requires. Keep the receipt. Lock through the frame to something immovable. Consider GPS. And read your policy's security requirements before you need them, not after.
