@Zagorath @zerakith recumbent trikes are excellent at low speed manouvers, which can be a boon in busy areas where any bike must be walked. I only once tried to corner too fast and that was faster than I corner on a bike anyway.

Hills are fine, in theory better than a bike as you have something to push against. So if you are light and have poor arm strength you can put out more power in a recumbent. Or just someone with legs stronger than that

They are trash at going through narrow spaces.
