Luna cycles Apex has probably the biggest ebike battery I'm aware of. They also have a bike called the Roam Fusion that is available with a 52V 34 Ah battery. The Apex is a high end custom built bike. The Roam is basically a vendor specific conversion bike built on a Giant Roam MTB frame. They are both mid-drive, and higher power (up to 2500 W motors), and definitely could create some legal concerns as a bike, the federal gov. would classify them as mopeds realistically.
For more realistic true ebikes, a high end option is Riese Mueller Supercharger is available with a dual battery setup that would give 50 miles of range unless you are traveling 28mph the whole time, cost is around $7500 IIRC. Stromer ST-2 or St-2 S is another high end bike with a big battery option (IIRC ~900 Wh) again cost is over $7000. These are both very well built and well reviewed bikes.
The best affordable option is the Juiced CrossCurrent S. It is available with a 52V 21Ah battery for $3000. This battery is actually bigger and more powerful than the Stromer (This is the bike I just ordered btw.) I've been researching for about 3 months before I decided to go with Juiced.
Good luck.

Production issues for sure. They can't keep the CrossCurrent S in stock, each shipment is mostly sold out before it even arrives at their warehouse. The biggest reliability issue I found was related to spokes breaking on the rear wheel. Juiced changed both the type of spoke they are using (went to Sapim brand spokes) and changed the geometry of the wheel spoke lacing. This appears to have resolved the problem, as I haven't read about owners of the newer bikes having spoke problems.
Also as far as range goes, take every bike makers estimate with a grain of salt. The biggest factor in range is the speed you are riding, anything over 20 mph starts to use exponentially more power due to wind resistance. Juiced does have a "Real world range test" on their site which demonstrates very well the effect of speed on range. Probably the best way to estimate the range of one bike to another is to calculate the "Watt Hours" Wh of the battery, as this is essentially the capacity of the battery. It is easily calculated by multiplying the Voltage (V) x Amp Hours (Ah). For example the Juiced 52V 21Ah pack is 1092 Wh. Stromers big battery is 48V and ~ 20.47 Ah for 983 Wh. The remainder of these bikes is similar enough that you can assume that the Juiced bike would have ~ 9% more range if speed, rider weight, etc were the same.

Starting with a full charge, I am getting 40 miles out of my Bosch CX bike with the Diore xt 11 speed. There is 10% remaining on the 500 watt battery. I weigh 210, live in a hilly area and usually loose and gain between 600 and 800 feet in a 15 mile ride. I keep the bike mainly in eMTB mode (variable automatic assist level) and the bike produces about 60% of the motive effort with me contributing an average of 40%. I am quite satisfied with these results.
