Product overview
The SHIMANO SM-EWSS1 speed sensor magnet adapter is a part designed for electric bikes equipped with a sensor-based speed measurement system. Designed for use with 6-hole disc brakes, it installs the magnet required for speed detection at disc level, ensuring consistent reading of riding information by the electric assist.
Benefits for the user
By enabling the magnet to be positioned appropriately on a 6-hole disc configuration, this adapter facilitates integration of the speed sensor into the assembly, and contributes to speed detection that can be used by the assistance system. It's a practical solution when replacing a part, refurbishing or adapting an assembly on an EAB (electrically-assisted bicycle).
Technical specifications
Type: magnet adapter for speed sensor.
Model: SM-EWSS1.
Mounting: compatible with 6-hole disc brake configuration.
Brand: SHIMANO.
Recommended uses
Recommended for installation or replacement of a speed sensor magnet adapter on an electric bicycle, especially when the wheel/brake configuration is a 6-hole disc. Also suitable for servicing to restore functional speed detection as part of assistance system diagnostics or maintenance.
Compatibility
Compatibility explicitly stated: mounting for 6-hole disc brake. No other compatibility (systems, motorizations, sensors, series, VAE models) is specified in the information provided.
Expert advice
When fitting, make sure the magnet and speed sensor are correctly aligned and securely fastened, then check speed detection after reassembly (workshop stand test or short test). In the event of irregular assistance or unstable speed display, first check the positioning of the magnet, the condition of the sensor and the tightening of the disc bolts (without modifying the tightening torques recommended by the brake manufacturer).
