When it comes to bike security there are variety of different bike locks out there – chain locks, cable locks, folding locks, security ties. But in this blog, we’re talking all about the D-lock (or U-lock as it often called).
Why use a D Lock?
D-locks are considered one of the best locks for a bike, and consist of a strong steel shackle and a retaining bar, which locks the shackle in place. They also feature strong locking mechanisms, and will usually have a double dead lock and anti-rotation locking (as do all Hiplok D locks). This means a thief would have to cut through both sides of the lock to release the bike.
Within the D-lock category there are a range of security levels to cater for different requirements. In the UK, locks are categorised by independent security accreditation house, Sold Secure. They test each lock with different attack methods and assign each lock a rating based on what tests it passes. Bicycle locks will be classified as Bronze, Silver, Gold or Diamond – you can read more about Sold Secure in our Sold Secure Explained blog.
Hiplok D is our entry level compact D Lock and is rated Sold Secure Silver, which is still classed as a high-security lock.
The Hiplok DX is our maximum-security D lock and has been classed as Sold Secure Diamond. The diamond rating offers an extra high level of security and is an ideal E-bike lock or perfect for bikes of high value.
How to lock your bike correctly
Having a good bike lock is one thing, using it correctly is another.
- When locking your bike, always make sure you attach the lock to your frame. Don’t just put the lock through your wheel, which can be quickly and easily removed, leaving you with just a very secure wheel when you return.
- That said, wheels can also be a target for thieves as they can be fairly expensive, especially the back wheels which hold the cassette. So, if possible, try to place the lock through the frame and the back wheel.
- It’s also worth taking a secondary lock with you to keep your wheels and accessories safe. The Hiplok DXC for example comes with an integrated cable for this purpose. Or you could keep a Z LOK handy to secure your wheel to the bike frame for instance.
- Another important thing to consider is where you choose to lock your bike. Somewhere busy, with lots of traffic is best, as it will generally deter a bike thief from even attempting to steal your bike. Whereas, if it’s down a quiet alleyway, they are much less likely to be disturbed whilst they work on breaking the lock.
- Be careful what you lock your bike to. A purpose-built bike stand is the best choice, but failing that, just make sure you’re not locking it to something that can be easily cut through, such as a wire fence.
- One of the most important security tips is fairly obvious, but make sure you take a bike lock with you whenever your ride. Our range of D locks at Hiplok each feature our Clip + Ride system. This makes it super easy and convenient to take with you, allowing you to simply clip the lock onto belts and pockets, so there’s no excuse, even if you’re not taking a bag with you. But if you’d prefer to carry your lock on your bike, we have the DXF, which features a handy frame bracket – so your lock is always with your bike.
