The K-Traz U20S is the most powerful compact U-lock in the range. It is approved by the SRA, a certified and certifying organisation set up by a group of insurers, guaranteeing technical and mechanical characteristics that meet high security standards and tests. With a maximum security rating of 20, this lock is ideal for cyclists who regularly commute in urban areas and need to secure their bike, e-bike, Cargo or Longtail bike in unsupervised parkings.
Security Level 20 - For areas with a high risk of theft
Classe SRA
Reproduction of keys in case of loss. Unique serial number.
Optimal protection of your frame's paintwork
Less weight and reduced size
For safe and secure transport of your U-lock on your bike, we recommend using our K-Traz Holster (#4905) universal mount.
Perfectly adapted to cyclists, U-Locks offer an ergonomic design, easy to use and to carry.
- day and night parking in areas with a high risk of theft (high traffic areas, dense residential areas,...)
- overnight parking in areas with a moderate risk of theft (medium-sized cities, university campuses, etc.)
- Attached overnight to a bike rack on a car (make sure the bike rack is equipped with an anti-theft device)
This lock has a very high level of security but is heavier and bulkier than other models. This will make it less easy to carry, but it will work well for an e-Bike.
Your lock will be exposed to the weather, as moisture and dust as well as cold can affect its function. Care and cleaning of a lock will extend its life and keep it functioning properly.
