A friend of mine currently rides the V4 and really likes it. His final choice was between the V4 and Bird Aeris and he went for the V4 due to being a light lighter and having internal cable routing. Good bike to ride but I think they come up a little short, certainly shorter than the geometry would suggest. The front end also feels like it’s quite low but still manages to wonder a little on steeper climbs so need to keep that in check.
I have an Aeris and having ridden that and the V4 back to back I feel better on the Aeris, less cramped and more in the bike than on top of it, but this is subjective and depends on how you like your bikes to feel.
I’m using the Minarch Plus on mine with 6 bands and rebound 5 clicks out from slowest. The Aeris seems to like a slower rebound setting for me at least.
