Ultra-light, low-speed, short-range #MicroEVs should not be built with carbon fiber composites—which are not and never will be #sustainable, by their very nature, despite their strength/weight ratio.
They should be built with 100% #recyclable #steel and #aluminium #bicycle (or at most #motorcycle) #technology, with #replaceable, #biodegradeable plastics where it makes sense (like body shells), and #natural #materials where possible (like #textiles).
