But the point of bedding a freewheel in is to knock and burrs off the pawls and get the pawls to seat correctly in the drive ring. To do this you need to actually free-wheel around, that is roll at speed without pedalling. Pedalling continuously for 2 hours will do nothing to bed a freewheel in but coasting down a huuuuuge hill for 2 hours would, especially if you pedal at random intervals to ensure the pawls get a chance to fully engage properly and get themselves seated. Hope that makes sense.
In other news, change to rear freewheel and buy a Hope Pro2 .
