<p>A bicycle which is used for two people to ride parallel has twin-frame. When turning, the twin-frame bicycle leans with the rider to avoid overturn. There is a joint structure between the main body and the assistant body. The joint structure can transform as parallelogram. Besides, further spring elements can keep the twin-frame balanceable and steady. The three wheels, i.e. the wheel on the assistant body and the wheels on the main body, constitute a triangle, and make the twin-frame steady. The twin-frame bicycle is safe during riding.</p> |
