Compare the momentum of a semi truck moving 20 m/s and a bicycle moving 20 m/s

The formula for momentum is p = mv, where p is momentum, m is mass in kg and v is velocity in m/s.

An object's mass and momentum are directly related; as mass increases, momentum will have a corresponding increase, assuming a constant velocity. Thus, an object with twice the mass of another object - - moving at the same speed and in the same direction - - will have twice the momentum.
