Pricing across bike and scooter sharing follows a standard architecture nearly everywhere, even though the actual numbers vary by city: e-scooters and dockless e-bikes charge an unlock fee plus a per-minute rate, which makes them economical for short hops and surprisingly expensive for long leisurely rides, while docked public bike systems sell time-based access, day or multi-day passes, with rides under a threshold, commonly around half an hour, included free, making them dramatically cheaper for tourists who ride a lot.
On whether multi-day passes pay off: for docked bike systems, almost always yes if you'll ride more than a couple of times daily, since the pass converts unlimited short rides into a flat cost; just learn the re-dock trick, where docking within the free window and immediately taking another bike resets the clock on long routes.
