Hyperglide is the name given by cycling component manufacturer Shimano to a sprocket design in their bicycle derailleur tooth cassette systems. Check the freehub for wear to see if it needs replacing or just cleaning and relubing. To do this, firmly grab the splined body and give it a wiggle. If it moves more than a couple of millimetres side to side, replace it. What is the main difference between freewheel and cassette hub? The freewheel is a single-unit and the act of pedaling tightens the freewheel to the hub.
With the free rotation of the freewheel during coasting, there is nothing to put a reversing torque on the freewheel to unscrew it from the hub. The end result will be sporadic ghost pedaling when the bicycle is coasting. To fix this issue, you will have to replace the broken pawls, the freehub body, or the entire hub.
