u use ur hands and feet, each wheel has like a freewheel so you can pedal and hand crack at different paces
each pole of the frame is adjustable so you can make it longer, shorter, narrower etc
dont know about the chain slack, maybe the chains can be on super tight?
u lean to turn but maybe in the future theres a mechanism that allows you to turn by shifting ur bottom half and top half and different directions and the middle frame tube acts like a steerer
future versions can have a tummy rest/seat
for a few dollars more you can buy frame specific garmin mounts, hand crack bells, and a bottle cage
