The Fatfish Biggie Communication Manifold is the central connector that links your e-bike’s electronics into one system. It brings together the display, throttle, sensors, controller, and other components so they work in sync, delivering the smooth pedal assist and control the Biggie is built for.

When the manifold starts to fail, signals between components can drop out, causing issues such as the motor not engaging, the display showing errors, or the throttle cutting in and out. Replacing it restores clear communication across the bike’s electronics and brings back reliable performance.

This part is made for the Fatfish Biggie, with sealed connectors designed to handle the demanding conditions.
