Australian governments are considering mandatory product standards under the Australian Consumer Law for e-bikes, which would ban the sale of non-compliant devices.
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.
