20 degrees seems about standard for San Francisco. That's only a 5% grade in road parlance.

- michaelt 7y ago20° is a 36.4% grade [1]. New Zealand's Baldwin Street [2] is the world's steepest residential street, according to Guinness World Records, with a slope of 19°. San Francisco's Filbert Street has a gradient of 17.5° [3] and that's that's steep enough that it has steps. Of course, a road can be "very steep" and "normal for SF" at the same time! IMHO even if a road is very steep, if you're hiring scooters in a city the brakes (and geometry) should be good enough that an average rider can safely descend the city's steepest roads.

- therein 7y agoThe way that I was trying to eyeball it was "45° is is kind of like a stairway", this was probably half as intense as that. :)
