It's all in the Hills!
Most of our mopeds in San Francisco are equipped with extra strong throttles that can get you and a passenger up the city's notorious hills without a problem.
Recently, we've introduced a few mopeds with more standard motors. These will get you where you need to go, but, depending on the conditions, may not be strong enough to push you and a passenger up every hill.
TLDR: Depending on conditions, one-passenger mopeds will support you going up the hill, but may not support you and a friend.
