Serious Security That Holds the Line
This isn't another flimsy cable — it's a vetted piece of security craftsmanship designed to protect your ride outside the garage. The alloy lock head and 12mm steel cable deliver real resistance against cuts, while the five-digit combination lock gives you over 10,000 possible codes. We curated this lock because its high-strength alloy outperforms conventional materials by a factor of three. At $38, it's a small investment that pays for itself the first time it holds fast.

Vetted for Real-World Security, Not Just Shelf Appeal
Most bike locks sold at big-box stores are designed to look sturdy, not be sturdy — the kind of thing you grab off a peg without asking a single question. At Volt Trek, we only carry security accessories we'd trust with our own rides. This lock passed our vetting process because the alloy lock head and steel cable deliver genuine resistance, not marketing copy. The same craftsmanship standard that applies to our garage equipment applies here: if we wouldn't rely on it, it doesn't make the cut.

High-Strength Alloy That Outlasts the First Season
The alloy used here isn't off-the-shelf material — it's a newly developed high-strength alloy rated three times stronger than conventional lock materials. That means real resistance against bolt cutters and cable shears, not just a convincing finish. The 12mm thickness of the steel cable backs that claim up with physical reality: this is the kind of investment in gear that doesn't fold the first time someone tests it. Craftsmanship shows up in material choices before anything else, and this lock makes that clear.

25cm More Reach, a Five-Digit Code, and No Anchor Left Behind
Standard cable locks leave you hunting for the closest anchor point. This lock extends 25cm beyond traditional cable lengths, giving you real flexibility: wrap it around a street lamp, a fence post, a toolbox, or a thick tree trunk. The five-digit combination offers over 10,000 possible codes — no key to lose, no locksmith to call. It also secures beyond bikes: motorbikes, scooters, gates, lawn equipment. One vetted lock, built for wherever your garage ends and the rest of the world begins.

The Volt Trek Promise
We sell what we'd put in our own garage. If it doesn't meet our standards, it doesn't make the cut.
“Got this for my commuter bike and it's held up through two winters parked outside every day. The alloy cable feels genuinely solid — not the hollow rattle you get from flimsy hardware. Set my combination in two minutes flat. Exactly what I needed.”
