If you wants decent aerodynamics, you don't get a a "traditional" racing bike, you get a recumbent. Recumbents hold the world records for speed by a far margin and it's because they cut the aerodynamic profile in half.
They are known widely for being way more comfortable than traditional bikes (which is why most exercise bikes these days use 'bent form). You don't get saddle sores from them, but they are much better for your lungs and midsection as well, as bending down in the proper form in racing bikes practically crushes your middle. So I don't get your comfort assertion at all.
Of course, recumbents often are bigger and that's a down side, as well as visibility being a factor (the aerodynamic win trades off with being lower to the ground). And the ability to "hop" over objects. Uphill is reportedly tougher but I find that is more with newcomers because recumbents exercise different muscles, particularly midsection, and endurance comes from riding a long time.
I think a lot of the bad characteristics of recumbents is mitigated in the "crank forward" design of recumbents, which is a hybrid of the traditional frame of the bicycle and recumbent - pushing the crank forward like the name suggests, elongating the frame slightly but still being high enough and able to jump objects.
Google images has a ton of crank forward bikes to view.
As to the topic, I've been looking into a 1500 watt scooter. Can stand or sit. Can go up serious hills. Looks possibly small enough that I can take mass transit without them bitching about my luggage. Has a 20+ mile range, a little more if I don't go all out. Since it can go 35+ miles, 15 more than I'm willing to go on a scooter of that type, I think I can exceed that easily.
I would consider it seriously if my area rained a lot less than it does, like if I lived in Arizona. $1500 is still a lot, but compared to 5 or 10 years back, leaps ahead of what I could have gotten.
Previously, I was considering a gas powered Sym Symba (a Honda Super Cub remake) but I think that costs $3K, and only goes 45mph. With the electric scooter, I can go on bike paths, but on this, I would have to take roads, and that is too slow plus I would have to get a motorcycle license.
