@EatSleepRideRepeat - that is a very interesting comparison.- but I'd better not show this to Mrs Scoosh ...

. Actually, she does encourage me to get bike(s) and has said "Well go on then" when I suggest a trike ... a velomob might be a bit far for now, as 2 student (currently MSc and maybe PhD next year

What sort of gradient can you manage in the velo and what is 'not worth the walk' ?

10% ? 12% ?? 14% ???
