Hi Jenn, glad you found a bike that suits. You often have to compromise when you want a bike to suit different riding, ie to the station and also to get out on the trails, but it seems you have picked the right one for you. Welcome back to cycling!
I've just bought a new bike for commuting, a Trek 7.2fx (great blue colour with girly, swirly decals). No suspension but I too love the upright position, great for seeing traffic, although there's not much on the routes I go. Even better, when I get off it it doesn't take ages for my back to straighten up unlike the previous commuter I had
. It's a bit heavier than my previous one, certainly not as fast, but I love the wider tyres which means I can nip through the woods on my way home without worrying about the terrain
