i can confirm that. even though i have only a 12s setup with 1500w max i almost NEVER use the 9 gears at the hub. i just switch between the front middle gear (for launching) and then after some meters switch to the big one (for cycling), the rear gear's always set to the smallest one.
However, I will strongly challenge anyone claiming a human can't output more than 500watts during acceleration. Do the math on what it takes to go 0-30mph in under 6 seconds on pedal power alone
(1800watts) (18lb road bike)
Amateur bicycle racers can typically produce 3 watts/kg for more than an hour (e.g., around 210 watts for a 70 kg rider), with top amateurs producing 5 W/kg and elite athletes achieving 6 W/kg for similar lengths of time. Elite track sprinters are able to attain an instantaneous maximum output of around 2,000 watts, or in excess of 25 W/kg; elite road cyclists may produce 1,600 to 1,700 watts as an instantaneous maximum in their burst to the finish line at the end of a five-hour long road race. Even at moderate speeds, most power is spent in overcoming the aerodynamic drag force, which increases with the square of speed. Thus, the power required to overcome drag increases with the cube of the speed.
