About the Pedal Assist Sensor
This is the same PAS (Pedal Assist System) sensor included with every Temper e-bike kit. With it installed, the system reads your pedaling speed and applies motor assistance proportional to your selected PAS level — so the bike moves with you, not just for you.
Includes the sensor, magnet ring, and zip ties for mounting. Features a split magnet ring design so you can install it without removing your cranks.
- Fits most square taper and one-piece cranksets
- Split ring — no crank removal required
- If your crankset isn't compatible, add our PAS Adapter
