Is there a stronger suitcase style ebike/scooter than the motocompacto?

I’m really loving the square shape and design. I love the narrowness for storage in my vans purposes. Every other bike seems to be better . Even scooters . But I love the look of this thing too. So in at a standstill and before I settle im hoping somebody has seems. Clone , or lookalike that may be ANY amount stronger. The 12 miles , 300 watt motor and tiny tires are all something I’m not used to . I’ve used more rougher ebikes. I’m just here looking for ideas .
