Front Roller Brake Hub Lock For City Mobility Vehicles For OEM Projects
The Front Roller Brake Hub Lock is designed for city mobility vehicles and OEM front-wheel platforms that require smart front hub replacement with roller brake interface matching. Based on ZS3728, this page focuses on front-wheel security for projects where the front hub lock must match a roller brake layout.
ZS3728 combines front hub replacement, vehicle-side smart control and speed sensing in one front-wheel lock direction. It is especially relevant for shared mobility and city e-bike projects where front-wheel security, outdoor use and compact wheel integration are important.
Although the source backend category is Front Disc Lock, the parameter table lists Roller Brake Interface for this reference model. Upload content should keep both pieces of information accurate: use the original Product Category for the backend, and describe the brake interface as roller brake matching in the product content.
ZS3728 works as a smart front hub lock replacement. The lock receives vehicle-side commands and performs lock or unlock operation through the integrated front hub lock structure, while the speed sensing solution provides wheel movement information to the vehicle system.
The main matching point is the front wheel platform. OEM teams should confirm front fork O.L.D., axle diameter, spoke specification, roller brake structure, controller protocol and speed protection logic before sampling.
This product page is suitable for city e-bikes, shared mobility vehicles, fleet bicycles and OEM front-wheel platforms that require a front hub lock with roller brake interface matching.
