If you have one or more kids under age five or so and will haul them around a lot a bakfiets is the best way to travel hands down. I borrowed an Urban Arrow for three days around Madison and it was a dream. Easy loading, no trailers to try to maneuver and park, no front and rear seats on a bike not really designed for them, etc. The kids are right there and you can talk along the way. They are comfortable and have enough room for more stuff. Long tails are good too and a lot less expensive, but the kids are higher up, have their own seats to buckle and cargo plus kids can be more difficult.
As the kids grow and transition to trailer bikes and their own bikes, I expect you would use it much less.
I would suggest an electric assist if you have any hills or heavy loads to make it a true car replacement.
