**Brief Introduction**
SDZ01 pagoda‑shape key‑operated folding lock is SENDE’s classic distinctive‑profile folding lock. Different from mainstream rectangular folding locks, it adopts pagoda‑style multi‑joint alloy‑steel architecture enhancing joint‑level violence‑resistance. Folding locks combine U‑lock‑level cut‑resistance with cable‑lock‑style compact portability. When folded, it occupies minimal space and can be fastened directly to bike frames. Unfolded, it delivers sufficient working length to secure frames, wheels and external bollards together. Key‑operated for urban commuter mountain bikes, e‑bikes and e‑scooters. Its unique silhouette enables distributors to build differentiated product portfolios, proven as a mature best‑seller via years of market validation.
