Abstract:
The invention relates to a device for transporting human beings, comprising a frame, at least one tire extending in a peripheral direction around a wheel with a certain amount of elasticity, and a braking system. The braking power of the braking system is substantially independent from the elasticity of the tires. The invention also relates to a method for arresting said transportation device.
