The Official S3 Magnetic Lanyard is a specially designed safety kill switch that attaches to the handle bars of the bike and around the wrist of the rider. If the two become parted, due to falling off, the lanyard will become detached and the bike will become immobile cutting all power.
This unit is specially designed by S3 to easily fit replacing the standard On/Off handle bar Switch.
Fitted in seconds by simply detaching the On/Off switch connector and then plug in the Lanyard, no rewiring involved. Fits directly onto all bikes already fitted with a handlebar on/off switch. It is now an enforced rule at National, and International, events that bikes must have a safety power cut out device fitted and entry to events will not be allowed without one.
