    摘要： This frame (6) comprises a main tube (10), a head tube (22), a pedal assembly (32) forming a pedal circle (34), a seat tube (46) able to support a saddle (48). The saddle (48) is able to slide along the seat tube (46) in a plurality of intermediate positions between a fully retracted position and a fully extended position. The seat tube (46) is so arranged, with respect to the main tube (10), that, whatever the position of the saddle (48) is between the fully retracted position and the fully extended position, distances xa and xb satisfy a relationship: x a = A ∗ x b 0.9 A 0.95 wherein xa is the distance between an upper centre of gravity (52) of the saddle (48) and and the ground surface (4) and xb is the distance between the upper centre of gravity (52) a centre (36) of the pedal circle (34).

    摘要： A longitudinal two-wheel somatosensory car, comprising a car frame (1), and a front wheel (2) and a rear wheel (3) that are provided at the front and rear ends of the car frame (1). The rear wheel (3) is connected to a drive motor (5) which is used for driving the rear wheel. The two-wheel car further comprises a somatosensory platform (6). The somatosensory platform (6) is built-in with an attitude sensor. The somatosensory platform (6) in a mechanical transmission connection with the motor stator shaft (51) of the drive motor (5). The traditional balanced structure, in which the wheels are provided on the left and right sides of a balanced car, is changed to a structure in which the moving wheels are provided at the front and the rear ends. Therefore, both sides of a user's body, especially both sides of the feet are unobstructed, ie., there is no wheel that acts as a barrier, such that when the direction of the balanced car is out of control and the balanced car is about to fall over, the following situation will be avoided, i.e., a person cannot exit from a balanced car in time as the wheels are provided on the left and right sides of the body and a front handle is provided in front of the body. The electric car, which doesn't share the same design, is far safer to drive.
