Low step over must appeal but I guess only time will tell if can get along with it.

The 20" wheel ebikes are a lot handier than 'full size' wheel ones.
That model has a small, but neat, battery in the cross bar.
Range might only be 20 or 25 miles, but that's unlikely to be a problem for the proposed use.
It has three power levels which is enough, and gears which will be required for the climb.
Motor rating is not clear from the website, but it's Bafang which is a decent Chinese make.

The only thing I could see that mentioned watts at all, was right at the bottom of the page, but it's as watt-hours. 313Wh
Thats the battery. Watt/hr divided by the volts of the system, which is 36, gives a 8.7 amp/hr battery.

As Smudge says, watt hours is battery capacity.
What we are looking for is 36 volts rather than 24 for improved grunt.
I agree with Smudge, it appears the bike has a 36 volt motor, so all should be well.

As mentioned, I don't really profess to understand what makes one good and another bad, but the one she went to look at originally was 24v and 4.8Ah.
As Smudge say, this is listed as 36v and 8.7Ah.
Fingers crossed.
Thanks for the responses.

One thing that often irks me about hub motor ebikes and ekits, is that they rarely give the torque figures. You often have to find out what hub motor it is exactly and then go searching online.
Although lower torque motors will give more grunt on smaller wheels like this 20" folder, than the same system would give on larger 26" to 28" wheels. Which is obviously down to physics, but how much torque an ebike has can make a big difference, even when its legal 250W and 15.5 mph cut off.

Yes, its small wheels will help its climbing ability whatever the size of motor.
It's the same reason why Bromptons accelerate so well from rest - something the OP knows better than most.
All batteries sag, which means it will give more grunt when nearly full than when nearly empty.
Best idea is to keep the battery as close to fully charged as possible, which is also good for its overall service life.

He is loving it as it goes.
Gets him up the hill, which was the main thing, but also meant he could go out with my BIL a few weeks back. And not be left behind.
While he's very active for an 80 year old, it is starting to catch up with him.
