Very cool idea. Another approach would be to mount the kill switch directly under the brake lever on the handlebars? What I invision is a button, much like the built in kill switch on my throttle twist grip, but mounted under the brake lever so a firm squeeze would activate it. Casual braking would not move the lever far enough to press the kill button but a hard application would. I'm going to experiment with this and if it works I'll let you know. It would be our answer to a truck's "Jake Brake".
