Anyway, the regulations around PMDs are different from ebikes. There aren't power requirements, I believe, only speed ones. But it's not an area I know much about because I've never really cared much about it.

Thanks! I am not sure how hills are measured! I just know the one right around me is between 15 and 20, and causes the scooter to slow from 18.6 mph top speed down to 10 or so.

Don't use this info to calculate my weight lol.

I was wrong in my previous comment, because I accidentally used a calculator that did percentages wrong (it converted percentages of a circle, but in measuring grade, percent is rise over run (or height over width, if you imagine it as a right-angled triangle—you can take the tangent of the angle to get the grade). So 100% would be 45°.

So 15° is actually just under 27%.

The steepest hill in my city is 31%, so that's not outside the realm of possibility. But it is very, very extreme. Heck, even 15% is an extremely steep climb. An extremely steep popular climb near me averages out to less than 9%. It gets decent stretches which probably average to 12%, and those are exhausting to get up.

Hmm well my hill is not close to a 9% grade, itis less steep than that. There are some popular cycling training hills near me and it is less steep than that. I suppose I could calculate the slope from rise/run but I will just say it is a moderately steep Hill the kind you might walk up as a kid but as an adult you can downshift on a bike.
