When the Sex Panther first came out it was our job to test every aspect of the board. A team of interns went through San Diego, looking for the steepest inclines they could find. They reported back and the team went out to see how well the Sex Panther could handle these slopes.
All figures were calculated from an average of GIS Data, USGS Topographic Data, Google Elevation Data, and on Location Measurements.
The Sex Panther is rated to be able to handle a 30% Percent Grade Incline. Percent Grade = [Rise/Run] * 100
