Best range for similar watt hours

[Davegt2]

Hi Folks

hoping you can help!

I have an e8000 with a brace of 504wh batteries

it’s time to change the bike and wanted to know what the general consensus is on range. Assuming the riding conditions, support level, rider weight etc were the same

I have heard that the ep8 and 630wh is not a whole lot better than the e8000 with the 504.

bosch gen4 with the 625 seems to get the best range, even when compared to a levo with the 700wh

if anybody can actually put some real facts to this it would be really appreciated!

Thanks

Dave
