Assistance Needed!

Hey all,
We are a design team from the University of New Mexico in the mechanical engineering department. For our senior project we are creating a low-profile, light-weight longboard brake system. This brake will be designed for when a rider is NOT on the board. (Such as in the occurrence of a crash.)
For this project we need your help. We have created a market analysis survey, the link for which is posted below.

This survey should only take a couple of minutes and your input would be much appreciated.

Thank you
