Lightweight, easily foldable buggy for infrequent use on public transport, suitable from birth please!

[TimeWasting]

Had a Silver Cross Pop that I was planning to use to take 5week old on bus trips, but it's kaput, and has gone mouldy in the garage.

It's not going to be used very often or for very long at a time, but obviously I want her to be safe and comfy.

I've got a Buggy Snuggle, so built in footmuff not essential.

Any suggestions or tips?

Baby Jogger City Mini or Britax B-Agile.

The narrower and lighter the better (and foldable if you use peak time buses, as sods law decrees that the bus will already have maximum number of buggies or a wheelchair user on the wet day when you're running late).

I had MacLarens. Not all of them go fully flat, but should be OK for occasional use.

baby jogger city mini.

Those look good, but a bit more than I wanted to spend really.
I like the one hand fold, but if I'm folding the buggy it's because the bus is full, so I should be able to get someone to hold the baby.

Maclaren style was what I was thinking.

I liked my Chicco LiteWay. It's narrow, lies flat, pushes well for a stroller and looks much nicer than other strollers.

Maclaren XT is suitable from birth and easy to fold. It's not the lightest in the world but I don't know of a lighter one suitable from birth, only from 3-6 months.
It's also short enough and narrow enough to go sideways in bus wheelchair spaces so you can get 1 or 2 more on.

I like the look of the Chicco Liteway.

What about the Britax B-Lite?

I've got the petite star zia +, suitable from birth, I really like it...
