Looking to pick up a hybrid bike and need some advice. I am not a cyclist and am not in the greatest of shape. We live in a rural area so will be riding on paved roads but they are not super smooth. Will likely ride 5 miles tops per ride. Probably less most of the time. I want to be able to pull my 20 month old daughter in a cart behind me. Looking for something that will be comfortable and efficient. I have a 10 year old cheapo mountain bike from Walmart.

Here are some of the options I have considered but don't really know what the difference between the different bikes would be. I don't want to spend more than I need to for my type of riding. Looking to spend 450$ tops.

Trek fx or fx 1 (don't know the difference between the 2).

Trek Verve 1

Cannondale quick (cheapest one)

Whatever Walmart has in the 200-300$ range
