Choosing the right lock is essential for protecting your bike and meeting UK insurance requirements. Most insurers expect a Sold Secure rated lock — typically Gold or Diamond for bikes over £1,000, and especially for e‑bikes.
ABUS offers one of the most complete security ranges on the market, from maximum‑security D‑locks to flexible chains and compact folding locks. This guide breaks down every ABUS lock available at Wheelbase and helps you choose the right one for your bike, your environment and your insurance policy.
Understanding ABUS Security Levels
ABUS uses a 1–15 scale to show how resistant each lock is to cutting, twisting, leverage and picking.
| ABUS Level | Protection Level | Best For |
|---|---|---|
| 1–4 | Basic | Low‑risk areas, kids’ bikes |
| 5–9 | Mid‑level | Everyday commuting |
| 10–12 | High | High‑value bikes in moderate‑risk areas |
| 13–15 | Maximum | E‑bikes, premium bikes, high‑risk areas, insurance compliance |
Most insurance‑approved locks sit at Level 12–15.
