Since June 2019 the Flash scooters are being rebranded as CIRC. CIRC operates a fleet of hundreds of free-floating electric scooters throughout Zurich. You simply download its app and register your phone number and credit card and then its map will show you where the next CIRC scooter is located. You can unlock it by scanning the QR-code on the scooter. Unlocking costs 1Sfr, then it's 0.35Sfr per minute. The scooters are easy to use and definitely fun to ride. Just use your right thumb to press the throttle to accelerate and brake with your other hand. It's recommended you wear a helmet and you're obliged to use the street like a bike. Using sidewalks is prohibited. When you're done, park it (without blocking sidewalks) and finish the ride in the app.
