**Brief Introduction**
SDZ14 wide‑body rectangular folding lock addresses insufficient impact‑resistance of narrow‑segment conventional folding locks by widening lock‑blade cross‑sections for more uniform stress‑distribution against prying and hammer‑blows, mitigating deformation‑failure risks. Key‑operated with frame‑mount bracket for fold‑away portability. Targeted for customers requiring elevated security grades for e‑bikes and high‑power e‑bikes.

**Material & Craftsmanship**
Widened quenched alloy‑steel lock‑blades for enlarged stress‑bearing cross‑section. Reinforced hinge rivets. Wear‑resistant scratch‑proof engineering‑plastic bumper shell. Precision anti‑drill copper key cylinder. Frame‑mount bracket included as standard.

**Key Features**

1. Widened alloy‑steel lock‑blades greatly improve anti‑pry and anti‑impact performance via enlarged force‑bearing surfaces.
2. Reinforced hinge rivets prevent loosening over long‑term repeated folding usage.
3. Anti‑drill copper key‑cylinder resists technical picking attempts.
4. Fold‑compact portable design with frame‑mount bracket for on‑bike attachment.
5. Comprehensive OEM support for custom shell colors, laser‑engraved logos and color‑box packaging.

**Application Scenarios**
E‑bikes, high‑power e‑bikes and mountain bikes for high‑security‑requirement parking scenarios.

**OEM & ODM Service**
Custom appearance, logos and packaging. Stable lead‑times for large‑volume foreign‑trade orders.
