This is the most upright bike I have. It's more upright than my hybrid, which puts me in a leaning-forward rather than leaning back. And sometimes back rests are a good thing to have! Pardon the sleeveless jersey, it was 106F that day.
RANS makes a line-up of bikes which they refer to as "crank forward." Electras are OK, but RANS is higher quality.
