I have also observed that bars are too wide for me make the bike feel twitchy/unstable. As you can see with the bar upgrade pics, I cut them down a fair amount to match bars original bars. That being said, I bought this bike from a friend who told me they cut the original bars down to fit her. It was also a two step process - make the first cut for less than expected, take it for a ride, and then make the second cut if necessary.
