I finally made a decision! My husband patiently shopped with me at 11 different bike shops (many of them with three or four or five visits each) all over the state and patiently waiting while I rode (and rode and rode) every kind of bike. He even rode them for me to help give me another opinion. And I finally (FINALLY!) found the bike that felt just right!

I ended up buying the Giant Alight (which was the Escape until they changed the name for 2015.) (Here!) It looks like this:

Isn't it pretty? They were trying to put me on bigger bikes at the last store I shopped at because I'm fairly tall (5'8") but I couldn't even straddle the top bar unless I was on my tippy tippy toes- almost ballerina style. My legs are pretty short and my torso is longer. So I ended up with a medium, which feels good so far. It's hard to tell exactly how it will fit when my starting-to-get-in-the-way pregnant belly is gone. I know I have the seat lower than I should right now, since I am a bit nervous starting out and definitely want to be able to catch myself if I tip.

My husband and I went out on a quick 5 mile ride tonight and it was so fun! I wasn't sure I'd even be able to do one mile, but we just flew along. I'm going to need to sort out the (seemingly inevitable) behind discomfort, which isn't terrible, but a little sore, and find a way to position my body so my wrists aren't tired, but all in all I'm pleased at how easy it went. My form is definitely weird right now, but I can ride weird for a few months until the snow flies and then start fresh in the spring after baby is here.

Thanks SO much for all the help and assistance! I'm excited to have found such a friendly place!
