Ours are full size ebikes.
In fact they're the old (best) sort of Kalkoffs that are a few inches longer in the frame to make room for the battery.
Wonderful bikes, still good as new after over a decade of light use, but they are quite tall and very long, so they reach almost all the way across the width of the van, one each side of the boot, with other boot clobber in between them.
We also have a small bike trailer that (just) fits in between them in the boot, but it's years since we last used that.
It's really for when you stay somewhere and need to do a shopping trip on the bikes - and we tend not to stop anywhere for very long at a time.
