104BCD Bafang-Compatible Spider

A dedicated metal spider adapter designed exclusively for Bafang mid-drive e-bike motors — compatible with BBS01, BBS02 and G340 models. Features precise 104mm bolt circle diameter and supports 38-tooth chainrings. Constructed from durable black metal, it weighs 125 g and installs using standard crank bolts. No modifications or supplementary hardware required. Each order contains one spider adapter. Cosmetic differences between manufacturing batches are normal and unrelated to structural or functional performance. Measurement tolerances of ±1–3 cm apply only to external packaging dimensions, not to critical interface features like BCD or mounting depth.
