Handy hints and tips to help with your cycling practice

There are four types of bike locks: cable locks, folding locks (segments), chains and D-locks. You'll also need to consider the two main criteria when choosing your bike lock; the level of security (actual or perceived) and the fastening system. Don't forget to consider how easy your lock needs to be to transport based on your riding and parking habits, how long you need it to be and the level of flexibility you need.

1. Safety

B’TWIN and the CNPP, an independent laboratory, have devised a test for assessing how secure a bike lock is in real-life situations, on a scale from 1 to 10.

The B'Secure Scale

Bike locks with a score of between 1 and 4 are recommended for securing your accessories (helmet, basket, saddle, wheel), and bike locks that score 5 or more are suitable for locking up your bike.

The higher the score, the better resistance the keyhole will have to lock picking and the better the body will withstand attacks by expert thieves with increasingly sophisticated tools.

But remember, no bike lock is unbreakable. Instead, they are intended to dissuade potential thieves from trying to steal your bike.

2. The Fastening System

Not all bike locks are created equal. Each design offers a different level of protection, so you need to get to know each one to understand what’s best for you.

Cable Locks

Light, compact and easy to carry, cable locks are great for securing your bike accessories (bag, basket, saddle, helmet, etc.) but aren't enough for the bike itself.

Folding Locks (Segments)

Folding locks are compact and easy to transport too but are also very resistant to damage, so offer a higher level of security to cable locks.

Chain Locks

Chain locks come with links of all shapes and sizes and different levels of security, allowing you to easily lock your bike to a fixed point, lock several bikes together, or attach your bike to its wheel. They also come in different lengths to suit your needs.

D-Locks

The go-to, high-security deterrent, D-locks come in different sizes and are used to attach one or several bikes to a fixed point. They offer the same level of security as a chain but are lighter and can be mounted on your bike.

"I strongly recommend locking your bike to a fixed point (like a bike rack or street lamp) through its frame, avoiding the lock touching the ground if possible. On the ground, it’s more vulnerable to being struck by a hammer or mallet.

If the size permits, your bike lock should also secure your rear and/or front wheel.

Locks for accessories should at the very least hold these items to the bike's frame, and shouldn’t be used for locking up the bike itself.

Lastly, a combination of several different locks will make your bike even more secure."
