This will be a commuting and touring bike. I want to easily roll my folded bike into grocery stores and cafes.
Heaviness isn't a big consideration for me - because I hope to predominantly roll it around.
Reading on frame failure stories, I'm leaning towards bikes with no hinge in the main frame; or maybe a bike with alternative hinges.
I'm going for 20-24in wheels which will give me a better ride up hills and on bumpy terrain.
Folded size isn't super important, just needs to fit under a desk which I'm sure all of them do.

I'm 5 foot 5 and average weight, in Canada. I'm cool with spending as much as you'd spend on a regular bike.

What do you think?
