I'm looking into side by side options as have just remembered in the depths of time my friend fitted her obaby umbrella fold one through my front door thus it must be possible! So I'm compiling a list of 73cm all terrain type ones and I'd appreciate help!
Mountain Buggy Duet
Mountain Buggy Duo
Bumbleride Indie Twin
Air Buggy Mimi Double
74cm looks like it may scrape through so:
Stroll Air My Duo
Bugaboo Donkey (if only)
and.... what did I forget/miss???
Thank you!
