Running and cycling are two unrelated sports activities, but the seatless running bike introduced below is specially designed for running to combine these two sports. It is specially designed for runners by Australian startup Run4. When pedaling, the movement trajectories of the soles of the feet and legs are the same as running on the actual ground. It has the same exercise effect and is essentially different from ordinary exercise bikes. It exercises all relevant muscles and reduces the impact of the foot on the ground, reducing the chance of injury. Also, it can adjust the resistance by switching gears to suit the needs of different people.
