The bottom line The reach-per-euro choice. Take it if the problem you keep hitting is stands that are too thick to get a D-lock around.
Toptrek’s folding lock is the cheapest way into a lock format that actually solves a geometry problem.
What the manufacturer publishes
Five millimetre links in a high-strength alloy, described as resistant to cutting and shearing, with an outer layer intended to protect frame paint. Eight joints, each rotating through 360°. Unfolded length 94 cm. A double-sided B-class cylinder with milled teeth on both faces. An adjustable-diameter bracket for a range of seat tube sizes, plus a one-year warranty.
Where the reach matters
Ninety-four centimetres is a lot for a folding lock, and it is the whole argument for this one. A D-lock secures a frame and a wheel to a slim stand and stops there; at 94 cm you can go round a thick post, a wide railing or an awkward municipal stand and still get the frame and a wheel inside. That is a real category of parking spot that a D-lock simply cannot use.
Where it sits against the others here
At 5 mm, the links are thinner than the folding locks above it in this hub, and the cylinder class the maker states is not tied to a named independent scheme. Toptrek describes the lock as resistant to cutting and shearing; that is a manufacturer statement and we report it as one.

What we like, and what we don't
Strengths
94 cm unfolded, so it goes round thick posts a D-lock cannot reach
Eight joints rotating through 360°, which is what makes a folding lock usable in awkward spaces
Adjustable-diameter frame bracket included, so the lock travels on the bike rather than in a bag
Compromises
Not currently listed on the French market — the buy link falls back to a local search there
The manufacturer states a B-class cylinder without naming an independent scheme
At 5 mm, the links are the thinnest in this hub

Questions people actually ask
How long is this lock unfolded?
The manufacturer states 94 cm. Only the TITANLOCK in this hub is longer, at 100 cm, and it costs around three times as much — so this is the longest reach available at the entry price.
Does it come with a bracket?
Yes. The manufacturer supplies an adjustable-diameter bracket described as fitting a range of seat tube sizes without damaging paint.
A hardened steel folding lock at 85 cm from a long-established German bicycle parts maker, supplied with three keys and a frame bracket, and the best-selling lock in this hub.
Best for: Everyday city parking where a serious deterrent matters more than a certified grading.
14 mm shackle · ADFC recommendation stated · 1.7 m cable
A large D-lock with a 14 mm hardened shackle and an ADFC recommendation stated by the manufacturer, supplied with a 1.7 m cable for the front wheel and accessories.
Best for: Anyone leaving a bike in a city where theft is a real prospect, and who is prepared to carry the weight.
The combination-code folding lock in this hub — 85 cm, eight links on hardened rivets described as waterproof — for riders who would rather not carry a key at all.
Best for: Riders who share a bike, or who are tired of carrying and losing keys.
