FEREI's patented magnetic connection system optimizes the traditional durable structure. Unlike the conventional threaded ring which is firmly attached to the hub shell and difficult to remove even with special tools, the magnetic system’s ring is manufactured using wire cutting technology, providing higher precision and tool-free assembly and disassembly.This convenience allows for easy changes to different tooth counts based on riding needs and simplifies maintenance. The high-precision magnetic system enhances the riding experience and versatility, offering greater strength compared to threaded rings, making it entirely reliable even for e-bike applications. Available in 46mm, 50mm, and 60mm rim heights, it excels in agility, rapid acceleration, and a light pedaling feel, allowing you to achieve maximum speed.
