Can I make this bike fit me?
Years ago, the US Airforce commissioned the design of a 'perfect cockpit' for a new fighter, spending millions measuring and testing pilots and coming up with the right cockpit for the perfectly average pilot. Only to find there was no perfectly average pilots to fly plane. After that, they made planes with cockpits adjustable to the actual pilots that was flying the plane.  

Bikes take this further - the frame is not adjustable without making it heavy and unreliable, and unlike an aircraft, frames are relatively cheap compared to the the rest of the kit. Its cheaper and gives better bikes to make different frames. 

All that aid, the bike might fit you - The US Airforce never found their perfectly average pilot, maybe the manufacturer of that E-bike has found there perfectly average rider in you.
