As long as you always stay on paved roads an adventure style bike is useless. There's everything out there from sporty to comfy and all in all it's just better. Only if you are very tall and/or have long legs, the adv style bike might come handy on Pved roads, but still in general the suspension will be too soft.

"Because we shouldn't have to."
