GRIFEMA GA1201-12 Heavy Duty Chain Lock, 120cm
A 120cm heavy-duty chain lock with two keys and the best rating in Amazon UK’s lock bestsellers. Long enough to reach through frame and wheel to a solid anchor point — the length most riders actually need.
Honest security note: cable and chain locks are deterrents against opportunist theft — no lock at this price carries a Sold Secure rating. For high-value bikes and e-bikes, pair with a Sold Secure Gold/Diamond-rated lock and never rely on a cable alone.

Description
Bike Chain Lock — if that’s what you’re shopping for, here’s the honest lowdown. The eternal bike-lock problem: U-locks are strong but can’t reach around awkward anchor points; cables are flexible but cut like string. The GRIFEMA GA1201-12 chain lock is the middle way — heavy-duty chain, two keys, and the best rating in Amazon UK’s lock bestsellers.
Why this lock
At 120cm it reaches where U-locks can’t: through both wheels, the frame, and around the thick posts and railings that are often the only solid object available. The hardened chain resists the casual attack, and the length means you can lock the way you’re supposed to — frame and wheel together, to something that doesn’t move.
Who it’s for
- Commuters with awkward lock-ups — railings, thick posts, bike hoops
- Riders who need one lock for everything
- Anyone who’s found a U-lock won’t reach
Honest security note
Chain locks are deterrents against opportunist theft — no chain at this price carries a Sold Secure rating. For high-value bikes and e-bikes, pair it with a Sold Secure Gold lock, and always lock to something solid. Check the chain length suits your typical lock-up before ordering.

Bottom line: for bike chain lock, this is the verified bestseller with the ratings to prove it — and buying through Buzzing Bikes costs you nothing extra.
Locking like you mean it
Most bike thefts succeed because of technique, not lock quality. Lock the frame and wheel to something solid and immovable, fill the shackle so there’s no room for levers, and position the keyhole downwards so it’s harder to pick or fill with glue. At home, keep the bike out of sight from the street and register it free at bikeregister.com — a registered bike is a hard bike to sell.
