Description

Product Overview

Throttles and PAS sensors decide how smoothly an e-bike starts. LeafDay supplies twist throttles, thumb throttles and half-twist versions, together with pedal assist sensor discs in several magnet counts for different cadence feel.

Both parts use sealed connectors and are supplied with the cable length required by the frame. Markets that restrict throttle-only operation can be served with PAS-only configurations.
