A magnetic emergency relay switch could stop the main power source in case the rider fall. A magnet leashed to the rider could do the job.

First test of the jet turbine I made with Toto s template. This is the first version, I didn t try the new propeller.
Only 500w on this vidéo, I need bigger motor.
