If you're talking about the two-stroke in frame 'happy time' engines, then 'No, it's not gonna sound like a Whizzer'.
It's going to sound more like, say, a 1970 Suzuki 125 trail bike. "Zing, zing, pop, sputter" A group riding together sounds like an invading army of angry hornets.
Of course, there are plenty of other engines out there. Many of them are four-stroke. But I don't think they sound like a Whizzer, either.
It's a pity, but these motored bikes don't rate very high where their sound is concerned.
