Businesswoman Terry Annecke added her skills to the company at Businesswoman Terry Annecke added her skills to the company at time of start up, and, more recently, BST employed carbon time of start up, and, more recently, BST employed carbon composites engineer Andrea Pretzler (Toyota F1, Motoczysz and composites engineer Andrea Pretzler (Toyota F1, Motoczysz and significant experience in motorcycle design and construction) in significant experience in motorcycle design and construction) in Austria.Austria.

CAD design processes which involve 3D digital solid modeling. The CAD design processes which involve 3D digital solid modeling. The solid models are subjected to various pre-determined load cases, solid models are subjected to various pre-determined load cases, the results of which shows the peak stresses and deflections. After the results of which shows the peak stresses and deflections. After evaluation of the finite element stress analysis, the 3D solid model evaluation of the finite element stress analysis, the 3D solid model can be modified to alleviate any potentially high stresses or can be modified to alleviate any potentially high stresses or unnecessarily high deflections. This process may be iterated a unnecessarily high deflections. This process may be iterated a number of times before the final design solution is achieved.number of times before the final design solution is achieved.
