Gonna second the at least give Specialized Vita a look recommendation. I was looking at the Trek FX series, and also the Vita. After comparing components and price and trying them both, I ended up focused on the VIta - but then went to the shop and did a bit of a left turn

Ended up with a Specialized DOlce Sport (their entry level road bike), but swapped out the tires to 25cc because I was a bit afraid of the skinny road bike.

As mentioned, the top tube on both is quite slanted and easy to get on and off.
