You don’t really need an e-bike to go from the Mission to SoMa as it is pretty flat. I don’t think it will take you much longer on a regular bike. But your statistic that you showed is a bit flawed as it includes people that commute from outside and into SF, hardly any of whom does so on bikes, so this methodology will always show bias against walking or rolling (I don’t know a better methodology, it is just something to keep in mind).
Even so, this methodology still shows 13% walks to work in SF in 2019, and 36% took transit. So if we thinking about the typical worker in San Fransisco, they do indeed either walk, bike or take transit.
If we are only thinking about a typical worker that lives in the Mission and works in SoMa, I wouldn’t be surprised if this goes well over 80% that walks, bikes or takes transit (and most likely a mix of all of the above). And I very much doubt they spend more than 40 min commuting each day in each direction.
