KT V12L (Waterproof)
Options
Integrated concentric PAS sensor with dual Hall elements and built-in 6-magnet disc, producing 12 signals per pedal revolution for responsive pedal assist. The V-series design slides onto the bottom bracket spindle as a single assembly — requires left crank removal to install but provides a flush, rattle-free fit. Dual Hall sensing enables forward/reverse pedal detection, preventing phantom motor engagement when backpedaling. Compatible with KT and most generic e-bike controllers.
In brief: Cadence pedal assist sensor. 12 pulses per revolution. From $8.
