2.3 Rider-bicycle system simulation
In order to obtain the optimal three-point position,
minimization of the square of the lower muscle stress is set
as the design objective, and the horizontal and vertical
coordinates of saddle are the design variables. According to
experience, the angle between the pipe tube and the ground
ranges from 68° to 73°[11]. In this paper, the angle ranges
from 65° to 75°. According to the established rider model,
it is assumed that the rider’s leg should be in the biggest
stretch state when the pedal moves to the lowest position,
and the leg is in the horizontal state when the pedal moves
to the highest position. Therefore, the extreme riding
