S3TR is a concept of single person vehicle for urban city area but is also capable of traveling in short distance routes out of town. The distance range depends on battery type and capacity but falls between 20 and 40 kilometers. One of the major requirements during design process was to include great fun while driving, so airplane-like controls and tilting mechanism to steer (like flying or skiing) are incorporated into this vehicle design to provide the right amount of fun for its rider. Second important requirement was the ability to fold fast for easy transport, and when folded, this concept vehicle should measure approximately as regular suitcase.
Steering is performed depending of selected mode; by leaning the vehicle at the side of a direction (tilting mode) or by simply moving the control column at the side of a turn while the vehicle and foot rests remain steady (fixed mode). Tilting mode is normal operation mode, more appropriate for normal and high speeds while the fixed mode is for speeds approximate to man pace, and offers better maneuverability.
This prototype was built by the use of only very basic hobby tools at inappropriate place and with limited budget, so it lacks some technical solutions and some are realized in a hard way. The purpose of the prototype was to demonstrate the functionality and to present the approximate design.
