Range remains the big limiting factor of ebikes for those who like to do day rides.
There was a reasonable leap forward in technology about 15 years ago with the introduction of lithium batteries - a vast improvement over lead acid.
But since then progress has been glacial.
The energy density of my 2009 Bosch battery is very similar to the latest ones.
Every now and again, some research is published which looks promising, but it never reaches the market.
The latest electric cars use very similar cells to ebikes, just lots more of them.
Batteries were big and heavy when they were invented 200 years ago, they are still relatively big and heavy today.
There is no magic wand when it comes to range, an ebike with a light and fit rider running minimum assist on flat roads will go a lot further than a lardy bloke trying to beast the hills.
The lighter weight ebikes such as the roadie style ones have a weaker motor and a smaller battery - we could call them 'light assist'.
Cannondale make a roadie ebike with the more powerful (and heavier) Bosch motor and a (heavier) 500wh battery which would be better for range than most lumpy flat bar hybrids with similar motor/battery combos.
To generalise, it comes down to a real world range of 40-50 miles, probably near 40 in most cases.
Some ebikes have an even heavier 700wh battery which will increase the range a little.
To be confident of 50+ miles it's really a case of carrying a spare battery, or in the case of my Riese and Muller, having a plumbed in twin battery set up.
The bike is German, so built to invade Poland, add the second battery, and you have a very weighty beast.
Manhandling it is hard work, so it's best suited to roadie rides where there's not much stopping or getting on and off.
@ColinJ didn't realise what a treat it was for me when I first turned up to his rides to find I could keep pedalling pretty much until the cafe stop.
Dave could consider a compact framed ebike with 20" balloon tyres, much easier to use for someone getting on in years.
This Cube has the same Bosch motor and battery as the big wheel bikes, so its performance will be similar.
One of these with a spare battery in a pannier bag would be a very handy rig capable of banging out the miles.

NB: Take no notice of the 'urban mobility/commuting' blurb. I have a similarly designed bike and have done 80+ mile rides on it.
