Public transport handgrips have been the same size for decades. However, different sizes of hands need different sizes of handgrips to grasp firmly and comfortably, preventing the hand from slipping out. Improvements based on ergonomics design have been made to the triangular handgrip. Three sides of the triangular handgrip are different in sizes, which are 1cm, 1.5cm and 2cm in radius.
The design of the notch on each edge of the handgrip is well-fitted to the girdle, hence the handgrip can be easily adjusted yet tightly buckle to the girdle. Passenger can flexibly change the side of the handgrip for the most comfortable preference.
