Background technique

For centuries, skating has been known and has been referred to as preferred leisure, movement and body-building. Roller-skate is created to simulate the skating on solid ground.The roller skate of first item is referred to as double ice skate. Double ice skate have the four wheels disposed in a manner of two rows.Double ice skate quickly and are easily grasped not as good as skate Make, but double ice skate are still very popular in the people of the sixties and the seventies.The new roller-skating epoch start from working as Nineties when straight-line open air roller skate is promoted to ordinary populace.Straight-line ice skate than double ice skate faster and It is easier to operate, but experience and be still not exclusively similar to skating.Straight-line ice skate have no chance to stop and break away using side to brake.Nothing By how, for straight-line ice skate user, braking be always challenge.

Several trials have been carried out to be further improved straight-line ice skate.
