Being a sensitive soul I tend not to blast past push bikes on my ebike.
If I'm gaining on a push biker towards the top of the climb I may hang back, knowing the push biker will blast off into the distance once over the summit.
I've also apologised for passing push bikes.
For example, on the way to Brighton when I was trying to catch
@ianrauk and chums in brisk mode.
I did rattle past two ladies on hybrids, but I also slowed for a second and briefly explained I was with the roadies up the road and trying to get back in touch with them.
Sensibilities, eh?
