Integrated PAS (Pedal Assist System) sensor. Designed to automatically turn on the electric motor during pedaling, making the ride as comfortable and economical as possible. The model features a monoblock design (sensor and magnets are combined into a single housing), eliminating the need to set the gap between components separately. Installed on the left side of the bicycle directly onto the bottom bracket axle.

Features and benefits

• Fast response and smoothness: Thanks to the 12 magnets, the controller instantly reads the pedal movement, ensuring a smooth start without jerks and a fast motor shutdown when pedaling stops.

• Integrated design: The sensor and the magnetic ring are made in a single sealed housing. This protects the magnets from displacement, mechanical damage, and dirt accumulation.

• Reliable water protection (WPC): The sealed round yellow connector guarantees stable system operation even during heavy rain or bicycle washing.

• Easy installation: The inner part of the sensor has splines for secure fixation on a standard bottom bracket axle. Requires no additional mountings or complex gap adjustment.

Important for buyers: This sensor is designed specifically for installation on the left side of the bicycle. Before purchasing, please make sure that your controller (e.g., LS-S1 series) has a matching round sealed yellow connector, or purchase such a connector from us.
