It starts to get big, but it can be pushed on one wheel when folded.
Furthermore, when one has loaded up the bike with more than a front and rear bag, its a chore to take down the bags to fold the bike anyway.
The bike has gone up trains, buses, van buses and of course cars.
A larger wheeled folding bike is a "bike first/ vehicular transport later" type of approach.
42mm tires are a good balance of speed on the road and handling off road.
A suntour /NCX suspension seatpost and a Meroca suspension stem takes care of all sorts of bumps for light trails.
