Recommendation for Carbon Hybrid Bike
I would recommend this based on my experience when I was starting to get into the sport and also bit of your other post.

I would encourage you to get an endurance fit road bike. It sounds like you will primarily be riding on concrete or asphalt vs. gravel or mountain biking. Plus it seems like you have a need for speed which is totally fine as I do too. Also, modern disc endurance fit bikes can do some light gravel rides since you can fit up to 32mm tires on them.

You do not like drop handles bars. I think you need to understand a racing drop handle bar has 3 positions on it.




Tops you are pretty much straight up and is used as a recovery
position or when cruising and you do not need access to the controls.

Hoods is where most road riders ride at and is still pretty
comfortable and upright. This is where most road bikers spend most of
their time and is similar to being upright on a flat bar.

Drops are used to gain full aero or for aggressive cornering/fast
descents. Most road riders on the road will not be in this position
their whole ride.




Based on your last post and being in the U.S. I would recommend going to a Trek Corporate store to find your next bike. Ask to look at a Trek Domane SL5. If you are between 5'7'' - 5'10''ish you will probably be a 54 size frame in Trek and probably Specialized too in my experience. Here are some reasons why I recommend this frame and made a similar decision in 2019 when I bought the same model (I have several thousand miles on that bike and do not regret the purchase one bit).



Endurance fit road bikes get you most of the aero a full aero bike
gives you, but you can usually get a more comfortable fit that allows
you to ride for long distances.

Again since new endurance bikes allow for wider tires, you have
some options to do light gravel rides with the same frame. Also this endurance fit frame gives you vibration absorbing bushing to make uneven pavement fell less jarring without losing much if any power transfer.

That model bike gives you 105 groupset, which in short is identical
to what the pros ride except ever so slightly more heavy. The good
part is as you wear out parts, you can upgrade to Ultegra or Durace,
which is exactly what the pros use.

Trek has bike fitters at their stores. I would ask a fitter to make
sure the frame is the right size for you. Note based on my personal
experience never riding a road bike, I wanted to chose a smaller size
frame, but fortunately the sales person was a former bike racer and
fitter. He basically said don't do it and when I asked why he said you
and I are the same size and there is no way I could ride a 52 frame. I
am glad he intervened as right now, I am progressing to making my fit
more aero and aggressive. Had I gone with the smaller frame, I think I
would have been way too jammed up riding vs. feeling like I can get in
a tuck but still easily pedal.

Trek has a no questions 30 day satisfaction guarantee on the bike.
I have never had to use this, but have used other Trek warranties. They
stand behind what they sell and usually do what is right by the
customer is what I experienced.




The other thing to make sure you do is make sure you have them ensure the seat is the right size for you. I would recommend something that has a cutout and short nose. This is what I use - Bontrager Aeolus Comp Saddle. I initially had the wrong size saddle and struggled to do 50 mile rides with padded riding shorts. With the right size saddle, I have no issues doing 50 miles with normal shorts on. I think a lot of people lose interest in the sport because of bad saddle fit and even worse is the advice of get more padding or padded shorts does not really address the root cause of a seat that does not fit your sit bone width.

Last piece of advice after making your purchase is go talk to your insurance agent and get a personal articles policy for your bike through the same people you have your renters or home owners policy. Also let them know you want it to cover damage from a crash. The personal articles policy will cover any damage to your bike without a deductible (e.g. crash, transport damage, theft, etc.) and it is pretty inexpensive peace of mind for a purchase that is 4 figures. I do not recommend a bike specific insurance as they are not as well regulated and are usually by off brand insurers that probably will charge more.

I personally would avoid hybrids, ebikes, gravel bikes because I feel they are not purpose built and I am sure I will get flack for it in some way shape or form via a comment below. Also, I would avoid expensive aluminum bikes due to stress cracks and other reasons. I also would avoid the desire to upgrade anything like wheels, handlebars, etc. until you hit a few thousand miles on the bike. I do not at all advocate buying speed as I think some people try to do that vs. training, but that is their prerogative.
