I'm looking for a steer on getting a new bike. I currently have a hybrid bike which I largely use for commuting or doing trips around the city. I'm looking to upgrade and would also like to venture into longer weekend trips when I can. I'd probably still keep the hybrid bike for the city trips as I wouldn't feel comfortable locking up a new bike on a street for fear of it getting robbed.
I understand that gravel bikes are well suited to more off road terrains (I don't really expect to be on many dirt roads or mountain trails), but I figure there is a benefit on the roads I travel as there are some very rough segments, speed bumps, potholes etc. I also am thinking of getting panniers to take the backpack off my back and I hear they're well suited to that also.
I considered a road bike but I felt this was a bit of a stretch given that I'd only have occasional casual long trips and the roughness of the roads I normally travel to work.
Based on the above, would I be right in thinking that gravel bikes the best step up from a hybrid?
