Weight is the honest measure of how much steel a lock actually carries · review
A 100 cm folding lock whose manufacturer states ART certification, with a protected cylinder intended to resist drilling and an anti-scratch coating on the links.
The bottom line The lock to choose if a named certification is what you need. Check what your own insurer actually requires before paying for one.
TITANLOCK’s folding lock is the first in this hub to name an independent certification rather than a self-assigned figure.
ART certification. A protected closing mechanism intended to keep dust and dirt out of the cylinder and to resist drilling. An anti-scratch coating on the lock body plus a rubberised bracket back, both aimed at not marking the frame. One hundred centimetres of length, presented as suiting city bikes, e-bikes, e-scooters and prams.
ART is an independent foundation, and its gradings are recognised by some insurers, particularly in the Netherlands. If your policy names a scheme, a lock that carries it is not a nice-to-have. We report TITANLOCK’s statement that the lock is certified — we are not a testing body and we do not verify conformity.
What the maker does not publish here is the ART level, which is the part an insurer usually names. That is worth establishing from the seller or the manufacturer before buying on this basis.
One hundred centimetres is generous, and the protected cylinder addresses the single most common complaint about folding locks in daily use: they jam because the barrel fills with grit. The anti-scratch measures address the second.
Not published. On a lock this long, weight is the specification that decides whether it gets carried, and its absence is worth noting before ordering.

ART is an independent Dutch testing foundation whose gradings some insurers recognise. TITANLOCK states its lock is ART-certified; we report that statement and do not assess conformity ourselves.
The manufacturer states 100 cm, which is the longest folding lock compared here and enough to reach around thick posts with a frame and wheel inside.
