Buy the FB350 if you ride upright comfortably and want the smaller folded footprint and the lower price. Buy the 400XL if a backrest and step-through decide whether you ride at all, or if you need its 300 lb listed capacity against the FB350's 225 lb. Posture and capacity decide this one; the folds are both competent.
Posture is the product
The FB350 is an upright: perch seat, forward posture, a cyclist's position scaled to a folder. The 400XL is a semi-recumbent: a wide seat with a backrest and an easy mount. Owners do not drift between these; backs, balance, and habit assign each rider firmly to one camp, and the camp matters more than any spec below it.
Folded shape and capacity
Both fold to a shorter length and roll, but the 400XL's seat and backrest make its folded package bulkier in every dimension. In exchange it carries a listed 300 lb user capacity against the FB350's 225 lb, the widest capacity gap in this hub's bike picks. Small slot or large rider: pick your constraint first.
Session shape
The upright suits shorter, brisker rides and riders who like to stand the pace up occasionally. The recumbent suits longer, steadier sessions, reading and screen time included, where the backrest converts willpower into posture. Match the bike to the session length you actually do, and adherence follows the geometry.

FAQ
Folding and Storable Equipment questions, answered straight
Which is easier to get on and off?
The 400XL, clearly: a low step-through and a chair-like seat are its design brief. Riders with hip, knee, or balance concerns should treat mounting as a first-order specification, above resistance levels and consoles.
Which folds smaller?
The FB350, in length and in overall bulk. The 400XL folds respectably for a recumbent, but a seat and backrest cannot fold into nothing, and its stored package should be measured, not assumed.
Can either handle daily hour-long rides?
The 400XL's posture is built for that session length. The FB350 can do it for riders who fit its seat and geometry, but owner feedback puts its sweet spot at shorter daily rides. Session length is a fit question; answer it before the fold question.
