It's a small three wheeled seated escooter/eskateboard/egondola for a small disabled weak one legged child afflicted by debilitating energy sapping Lyme disease, or similarly afflicted apprentice of extremely small stature, or a trained marmoset feigning symptoms, operated by a single push pedal assist (SPPAS) system? Easy push pedal requiring little energy expenditure (like the brake pedal of a car) to turn that crank with low force via a connecting rod, possibly linkage, springs, after that enclosed dynamo?/PAS sensor is bolted to the underside (egondola platform in between) of the what could be axle holders for the rear/front hub motored wheels? Might even be road legal if both motors are rated 125W and limited to 25km/h? I do hope so but again, I completely give up.
