GRIFEMA 120cm Bike Lock with 2 Keys – High Security Chain Lock for E-Bikes, Scooters and More

What it is and what it’s for

The GRIFEMA 120cm Bike Lock is a long, sturdy chain lock designed to deter theft for bicycles, e-bikes, scooters and more. With a 12mm diameter chain and a zinc alloy lock cylinder, it aims to be drill-resistant and hard to defeat. It includes two keys so you can keep a spare, making it less likely you’ll be locked out if you misplace one.

How it’s built

On paper, the lock offers a simple, robust approach: a 120cm chain and a locking mechanism safeguarded by a waterproof and dustproof cover. This cover helps prevent dust ingress and rust, potentially extending the life of the cylinder. The kit also comes with a fixing bracket, allowing easy mounting around a bike seat or frame when not in use.

Pros and what stands out

• Long reach: 120cm gives you flexibility to secure multiple points or wrap around fixed objects.
• Higher security materials: zinc alloy cylinder and 12mm chain indicate a focus on resisting casual removal and drilling attempts.
• Convenience: two keys reduce the risk of losing access, and the waterproof/dustproof cover is a sensible inclusion for outdoor use.
• Practical mounting: the fixing bracket helps keep the lock ready and within reach.

Limitations and what to watch for

• It’s not stated how the chain is treated for outdoor wear beyond the general waterproof cover, rust resistance is implied but not quantified.
• Weight is modest at 348g, which is convenient for daily carry but won’t feel heavy-duty to those seeking maximum security from very high-risk environments.
• The exact security rating or independent tests aren’t provided here, so if you prioritise certified security grades, you may want to compare with alternatives that publish test results.

Best use cases

This lock appears well-suited for day-to-day protection in urban and suburban settings—locking bikes, e-bikes and scooters to racks, rails or posts, securing gates, fences, tool boxes or even sports equipment when parked briefly.

Who it’s for (and who it isn’t)

• You’ll likely appreciate it if you want a practical, value-for-money chain lock with a long reach and two keys, and you’re not necessarily aiming at the absolute highest security level.
• It may not be the best fit if you’re in very high-risk areas or need a certified security standard, in that case, look for models with clear independent test results or higher chain/lock ratings.

When to buy

Consider this lock if you need a versatile, long-length chain that’s easy to deploy around bikes or other items you want to keep secure outdoors. The two-key setup helps avoid lockouts caused by missing keys.

Before you buy — quick checks

• Confirm the lock’s chain diameter and length meet your typical securing needs.
• Check where you’ll store the lock so the fixing bracket aligns with your bike geometry or mounting point.
• Think about environmental exposure, while there’s a protective cover, routine maintenance (wiping, occasional lubrication) can help longevity.

Practical comparison in context

If you’re choosing between a lightweight lock and a higher-security offering, this model sits in the practical, mid-range zone: longer than compact locks for versatility, but not claiming the most advanced security features or official test ratings. It’s a sensible bridge choice for everyday use when value-for-money matters.

What you’ll notice in use

In everyday scenarios, you’ll probably find it straightforward to secure your ride or gear, with the added reassurance of two keys and a designed-to-last cover. A common observation might be that, while the construction feels solid for routine urban commuting, it won’t replace a specialised high-security chain in high-risk locations.

Final verdict

Final verdict

It’s a solid pick if you prioritise length, practicality and peace-of-mind with a spare key. For casual to moderate security needs, and for users who want easy mounting and everyday versatility, it represents sensible value. If your security demands are higher or you’re in high-risk areas, you may want to explore models that openly publish independent security ratings.
