Evolution mini-9 anti-theft steel u-lock
$86.79
Catalog updated 2026-10-21
The Evolution Mini-9 offers a compact security solution without sacrificing strength, featuring a 13mm hardened steel shackle. Its smaller profile makes it harder for thieves to insert leverage tools like crowbars into the lock, effectively increasing its defensive capabilities. This size is particularly popular among urban commuters who value portability and high-level theft deterrence.
Equipped with a reinforced housing and a high-security disc-style cylinder, this lock is built to resist drilling and picking. The double deadbolt design ensures that the shackle is locked on both sides, requiring twice the effort to compromise. Its sleek design allows it to be easily carried in a bag or mounted directly to the bicycle frame.
The lock comes with three stainless steel keys, including one with a convenient LED light for visibility in the dark. A protective vinyl coating covers the shackle to prevent any damage to your bike's paintwork. This model is an excellent choice for those who need a high-security lock that is easy to transport during daily rides.
