>>1051836>how can I know a mini velo is for me?You want a mildly smaller, lighter bike that's easier to carry up stairs, easier to store inside your small apartment, easier to take onto the train, etc - and you're willing to compromise on the riding qualities of the bike to achieve that (the smaller wheels will do worse on rough surfaces/potholes/etc).
You don't need the ultimate compactness of a folding bike, and therefor you don't want that extra weight/complexity.
