Motor efficiency and wind resistance are nonlinear, so no: More watts means you won't go as far on a charge. Hard acceleration is inefficient, but especially so with direct drive hub motors. The power wasted can be very significant, especially when you realize that your contribution from pedaling decreases are motor input in increased.
Also, I worry about the safety of a trike like that at speeds above what you could comfortably pedal with its fixed gear.
