The change you made didn't make any difference to the bike lane tagging, and despite it being a major rode route, if the lane exist it should be tagged there. 

All you did was remove what type of route was there, and removing the bike lane tagging would be considered vandalism by the community since it's intentionally removing correct information. As much as it may be a busy route, we map what exists on the ground, so if a bike lane is there, tagging that one isn't intentionally is just incorrect.
