Locks for fleets and new-bike programs

Shared-mobility and rental operators need keyed-alike or master-keyed locks, durable finishes and replacement parts; bike brands want a branded lock in the box or as an add-on. Both run through our OEM program; stock models through wholesale.

No certifications, ratings or test data claimed. We describe what each product is made of, how it works and how it can be customized. We do not display certification marks or security ratings, publish test data, factory capacity or customer cases on this site. Test reports and certification documentation can be provided or arranged per order for the buyer’s market, as the brand owner requires. Bike helmets and lithium e-bike batteries are regulated products: the applicable standard (for example CPSC 16 CFR 1203 / EN 1078 for helmets; UN 38.3 transport testing and UL 2271 / UL 2849 / EN 50604-1 for batteries) is confirmed per SKU and per order with the supplier and an accredited lab before production. Labeling and claims are the brand owner’s responsibility.

Frequently asked questions

Which lock should a bike shop stock?

Most shops carry a U-lock and a chain or folding lock for main locking, plus a cable lock as a secondary or budget option.

Can locks be keyed alike for a fleet?

Yes, keyed-alike and master-key systems are available on selected cylinders, quoted per order.

Do your locks carry Sold Secure, ART or similar ratings?

No security rating is claimed on this site. Independent ratings such as Sold Secure (UK) or ART (Netherlands) belong to a specific tested model; if your channel needs one, the model is submitted to that scheme per order and the rating may only be printed once it is granted. Shackle diameter, steel grade and cylinder type are specified per SKU — we publish no break-time or attack-resistance figures.

What is the MOQ and lead time?

Both are quoted per SKU. MOQ depends mainly on the platform (an existing design vs. a new mold), color, logo method, packaging and the documentation your market needs; lead time depends on customization, documentation and season. Send your quantities and we confirm both on the quotation — see also the packaging & MOQ section of our specs guide.
