Bike Safety

Contrary to popular belief, tamper-proof locks do not exist.
Bike locks are intended to act as a deterrent, makingit more complicated to steal a bike.

A good lock has an anti-picking lock mechanism and is made out of materials requiring the use of specific tools, which makes theft more difficult.

What do we mean when we talk about security?

The security rating helps you choose the lock that’s best suited to your needs.
For this reason, Decathlon defined a test protocol with an autonomous laboratory, CNPP, based on real-life theft techniques.
This unique protocol gives each lock a comparable rating from 0 to 10 (10 being a tamper-proof lock).

Security rating.

This lock is certified by the external bodies ART2 and Sold Secure Silver.
These certifications are often required by bike insurance policies.

Resistant to friction

The cut and seams are designed to prevent friction and keep you as comfortable as possible while riding.
For example: the back of the jersey is long enough to keep your back covered when leaning over your handlebars.

 - On your right, a secure pocket (16 cm x 11 cm [6 1/3 x 4 1/3”]) with an easy-to-open zipper (even with gloves on!) so you can access whatever you need while riding with one hand, such as your tissues or tire levers.

Wear a helmet and gloves when mountain biking: not just for falls, but also to protect yourself from low branches! For comfort, wear a pair of padded shorts to prevent chafing. A water bottle or hydration backpack will keep you hydrated. And finally, puncture repair spray so you can finish your ride without needing repair tools.
