I also wondered about those 4 seconds, because I have a Go and had not noticed this "lag".
So I fired it up and video'ed the scooter spool up from zero to full speed. The video is attached - turn up the volume, you can hear when full speed is reached.
And for shits and giggles I did the same on the Genesis, video attached.
The spool up indeed took close to 4 seconds. That is not to say you are not going prior to that, just that full RPM's do seem to take about the 4 seconds mentioned.
The Genesis was faster to go from zero to full RPM's.
Turns out I can't attach videos, here are the links to the videos on my dropbox:

Yes! Thank you for posting. From the earlier posts, I had gotten the (wrong) impression that the Go! takes 4 seconds just to start going. Now I see that it starts immediately but takes about 4 seconds to ramp up to full power. That is definitely workable.
Also, it looks like your Genesis is a 3.x. And it's taking about 2 to maybe 2.5 seconds or so to ramp up to full power?
I just tried it with my Genesis 2.1. It seems to take more like 3 seconds to ramp up to full power.
The "spool up" on the Genesis is why I basically never unlock the trigger unless I'm clipping the scooter off. At least on my 1st generation it's far too slow.
Running the throttle with the trigger locked you get instant response.
If I'm understanding you correctly, you're comparing the Genesis where you either have the throttle (aka speed) set to Max (or whatever you want) and you're just starting and stopping by pressing and releasing the trigger, versus locking the trigger in the "pressed" position and then moving the throttle from Zero to wherever and back again to start and stop. Correct?
Your "1st gen" is a Genesis 600 or 1200? I.e. pre-Warp Core, aka pre-2.x?
I just tested that with my 2.1. Shot video of both and compared. It seems to take right at 3 seconds to get to full power no matter which way I do it. The sound of it ramping up is a little different between the two. But, the total time to get to full power seems to be the same.
If the Genesis 3.x ramps up quicker - as it seems to - that would definitely be a selling point (to me) for the 3.x vs a 2.x. The ramp-up speed on mine is totally acceptable. But, quicker would be nicer.
