Another unusual Flevehicle spied  by me in the workshop in 1992 was this obvious Industrial Design degree project, with an objective to demonstrate a human- powered van for, by the looks of it, inhouse post gathering and distribution. The trunk contains a rack for up to 4 standard- size plastic trays, of which the fifth hangs behind the seat. Because of its rather favourable weight distribution ratio, this Flevan is probably more stable, than the others from its stable[sic!]. Thus this construction does have some merit, might have worked. We'll probably never know for sure, however, because student projects like that, even rideable prototypes, seldom progress beyond the proof- of- concept stage.
