For the sort of journeys you describe the Strida probably fits the bill best -it would make a good companion to your KHS. Strida for shorter hops , commuting and 'smiles' and KHS for more serious training 'miles'

Hey Simple Simon - thanks for that. If I can find a Strida, it may be what I go with.
Price seems quite reasonable and it would make a good #2 bike. Probably a good ride for guests too as it doesn't seem intimidating.
Any comments on the different versions? I hear they keep making improvements and it might make sense to look for a recent model. ?
EDIT: I see one Strida on eBay, here:

Not sure what version it is...
