Stroller for a very tall and heavy 2 year old?

[Bluebellsfortwo]

My little girl has just turned 2 and she's very big for her age, currently she's 105cm and ~19kg. She's outgrown her current pushchair (nuna triv next).

I'm looking for a new one for her as I think we'll need to keep using a stroller for at least another year or so as we do a lot of walking and don't have a car. We live in London in a small flat so don't want anything huge or massive.

I was looking into the Baby Jogger City Mini GT2, seen it on sale for £220ish. Does anyone have any advice on this one or can recommend any others?

I had the BJ and a Yoyo for a bigger toddler in London (also no car). I found the Yoyo better as we used public transport a lot and it was easier for squeezing into lifts, not taking up too much width on escalators or tube carriages, and folding and fitting in the footwell of buses. If you are just walking everywhere, then the BJ is fine, but by toddler age we were visiting lots of places across town every week as they need stimulation and there are lots of activities on.
