Okay, I'll play.
I commute 30 miles each way to work. I have been doing this intermittently on my road bike for years. Finally got tired of fighting the wind and started researching ebikes. I researched for about 5 months before finally ordering. I finally decided on the Juiced CrossCurrent S, for several reasons, but the biggest were value and battery size.
I can't stress enough the importance of getting a big battery for longer rides. You need to take range estimates with a huge grain of salt.
FWIW, here's what I do. I live in Utah so my commute is quite hilly relative to most. I bought the CCS with the 52V 21Ah battery, but it is not currently available with that battery. The 48V 19.2Ah battery is a better value per Wh at any rate, and will do the job you need.
I only am charging my battery to 80% to increase battery life. (This is a big deal, as the battery is by far the most expensive part of any ebike).
I ride as fast as the road, conditions, terrain, and bike will allow. This means my typical cruising speed is 24-30 mph. My average speed for my commute typically ranges from 22-25mph, which includes traffic stops, etc. I mostly ride in level 2 (this is the midpoint assist level for Juiced). I also pedal hard all the time I am riding. If you plan to use max assist all the time and not pedal hard, you are going to use the majority of a large battery pack in 25 miles. I generally consume a little over 500 Wh which is about half the capacity (into a big headwind over 600, tailwind under 400) from the pack each way. This means I recharge at work. (You will want to recharge as well. All ebikes experience performance issues as battery voltage drops. Not to mention the damage done to the battery by discharging to near zero.) I definitely notice the performance difference near the end of my ride. This problem will only be larger with 48V packs.
I have put ~870 miles on my CCS in the 3 weeks I have owned it. It really is an awesome bike. I love riding it. Yesterday I rode home into a brutal 20 mph headwind. This does slow you down even on an ebike, but the difference is so much smaller. I would never have tried to ride home on my road bike in those conditions.
I test rode 3 other bikes during my research btw. The only other bike that rides as well was the Trek SuperCommuter8S. That really is a nice bike that rides smooth and strong. The Bosch performance speed motor is nice. There are 2 big problems with it relative to the CCS. First is the battery has half the capacity. This means based on my experience, it would be dead before I get to work everyday. Second, it costs over $2K more than the CCS with the 52V battery. (Its $3K more than the 19.2Ah battery version.)
Also, for commuting on mostly flat terrain, hub motors are probably a better choice for most people. Mid-drives by design add significant wear and tear to the drivetrain of the bike. Mid-drive motors tend to be far more pricey both upfront, and if problems occur.
The only other bike that I can think of that would do a good job for your long distance commute is a Stromer St2S, and it costs far more than the Trek, but at least the battery can handle the job.
