Bike locks · OEM & private label
Bike locks U-locks, chain, folding, cable and frame locks for your brand
A bike lock is bought with almost every new bike and e-bike, and higher-value e-bikes push buyers toward heavier, branded locks. TandemForge supplies U-locks, chain locks, folding locks, cable locks, frame locks and smart locks to bike and e-bike brands, bike shops, sporting goods retailers, e-commerce sellers and shared-mobility operators — with your colors, sleeves, keys and packaging. For scooters see electric scooter locks; for the whole range see bike security.

- Chain locks — square or hex hardened links in a nylon or polyester sleeve, with an integrated lock body or a padlock.
- Folding locks — riveted steel plates with a frame holster; compact to carry.
- Cable locks — braided steel cable with PVC jacket; coiled or straight; key or combination.
- Frame (ring) locks — fixed to the seat stays; plug-in chain or cable options; common on city bikes and e-bikes, including versions keyed alike to the e-bike battery lock.
- Smart locks — Bluetooth / app or fingerprint unlocking and alarm functions; need radio and battery documentation per market.
Materials and cylinders
Shackles, chains and plates are made from alloy or hardened steel; the steel grade, heat treatment, shackle or link diameter and coating are specified per SKU. Cylinders are pin-tumbler, disc-detainer or combination (3–5 dials). Lock bodies are steel or zinc alloy inside a plastic or rubber cover that protects the bike’s paint. See alloy steel in the specs guide.
Security ratings — honest wording
We publish no attack-resistance or break-time figures and claim no rating. Independent schemes such as Sold Secure (UK) or ART (Netherlands) test and rate a specific model; insurers in some markets ask for them. If your channel needs one, the chosen model is submitted per order and the rating is printed only once granted for that model. Labeling and claims remain the brand owner’s responsibility.
Keys, fleets and replacements
For fleets and rental operators: keyed-alike and master-key systems on selected cylinders, key registration cards, replacement keys and spare parts. For new-bike programs: frame brackets matched to your frames and locks keyed alike to the battery lock where the platform allows. Lights, bells and phone mounts can join the same shipment.

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 type is best for e-bikes?
Many e-bike owners use a U-lock or heavy chain lock as the main lock, often with a cable for the wheels; frame locks keyed alike to the battery are common on city e-bikes. The choice is yours — we supply all types.
Can you make combination locks?
Yes — combination cable, chain and U-locks with resettable or fixed codes.
Do you supply smart locks?
Yes, on selected platforms (Bluetooth / app or fingerprint). Radio and battery documentation for your market is confirmed 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.
Are your products certified or tested?
We do not display certification marks, security ratings or test data on this site. Test reports and certification documentation can be provided or arranged per order for your market, as your brand requires: tell us the destination market, sales channel and the standard or document your retailer or marketplace asks for, and the quotation confirms which documentation applies to each SKU and how it is obtained (existing reports for a platform, or testing arranged with a third-party laboratory). See the export compliance section of our specs guide or ask on the inquiry form.
