In my view that’s a less interesting question than bikes vs scooters. Bikes and scooters were by far the most popular by-foot wheels even before dockless. There are some pretty distinct tradeoffs. Bikes are sturdier, safer, require a little more work, usable on hills, and are optimal for short to medium distances. Scooters are cheaper, slower, easier to use, lighter, and optimal for short distances only. Scooters are crushing bikes right now. Will they continue to? If not, what would dent their meteoric rise?
