I have the one that can throttle and pedal, ngl i used to hate people who throttle without pedalling but then i start using the throttle and immediately “get” it. It’s fun, like a light motorcycle, though pedalling save power and can go further, but people often only use it for short distance. Less car on the road, slower than motorcycle, it’s no downside.

I still view those that shaped like a motorcycle, can go as fast as a motorcycle, but with a decorative pedal in disgust though.
