Parallel-Riding Bicycle, a three-wheeled Parallel-Riding Bicycle, a three-wheeled bicycle,bicycle, permitting operation by two people to permitting operation by two people to pedal jointly shoulder to shoulder that provides pedal jointly shoulder to shoulder that provides the means of transportation, exercise, the means of transportation, exercise, entertainment, and social life. For its entertainment, and social life. For its performance in mechanical term is just like the performance in mechanical term is just like the conventional bicycle, we can flexibly operate conventional bicycle, we can flexibly operate this three-wheeled bicycle and keep bicycle this three-wheeled bicycle and keep bicycle body balanced even on uneven ground. body balanced even on uneven ground. Besides, the configuration is made strong and Besides, the configuration is made strong and can be dismantled and assembled quickly.can be dismantled and assembled quickly.

The bicycle body comprises one conventional The bicycle body comprises one conventional single operator bicycle attached with one single operator bicycle attached with one auxiliary bicycle. Parallel-Riding Bicycle can auxiliary bicycle. Parallel-Riding Bicycle can be Mountain Bike, City Bike, or even Exercise be Mountain Bike, City Bike, or even Exercise Bike. Furthermore, for it’s steered by the Bike. Furthermore, for it’s steered by the principal bicycle rider so that it can be used principal bicycle rider so that it can be used by children, elders, and even the disabled.by children, elders, and even the disabled.

Parallel-Riding Bicycle has a set of coupling Parallel-Riding Bicycle has a set of coupling bars. Four rows of perpendicularly-arranged bars. Four rows of perpendicularly-arranged springs lined between the bars. Therefore, springs lined between the bars. Therefore, the three-wheeled bicycle can lean with the the three-wheeled bicycle can lean with the principal and auxiliary bicycle paralleled principal and auxiliary bicycle paralleled within a limited range to prevent overturn.within a limited range to prevent overturn.

Springs are interlaced between ends of joint Springs are interlaced between ends of joint configuration, which can resist deformation configuration, which can resist deformation and therefore maintain the stability of both and therefore maintain the stability of both principal and auxiliary bicycle bodies. Utilizing principal and auxiliary bicycle bodies. Utilizing quantity discrepancy of these four rows of quantity discrepancy of these four rows of springs and the location of hook holes to springs and the location of hook holes to change pulling force and therefore make the change pulling force and therefore make the auxiliary seat post remain level when it’s auxiliary seat post remain level when it’s motionless instead of leaning forward or motionless instead of leaning forward or backward.backward.

In case the principal and auxiliary bicycle In case the principal and auxiliary bicycle bodies encounter height discrepancy or are bodies encounter height discrepancy or are operated on uneven ground, for example, the operated on uneven ground, for example, the ground level in which auxiliary bicycle located ground level in which auxiliary bicycle located is higher than that of principal bicycle in the is higher than that of principal bicycle in the left side, the left end of coupling link will lean left side, the left end of coupling link will lean downwards as shown in the left exhibition. downwards as shown in the left exhibition. When this three-wheeled bicycle is turning, for When this three-wheeled bicycle is turning, for instance, turning right, it shall be like that instance, turning right, it shall be like that shown in the right exhibition.
