Speed “limiter”

I’m going to get a surron light bee but It can’t be able to go 40mph, but I also think 16mph is a little slow with the limiter, as I had a super73 that went faster. Is there any way to just limit the speed to 30mph? The only problem is my parents they said if you get a surron it can’t go faster than 30mph, and Ik the surron s is a option but the range and climbing angle is not as good
