Yes, there are several "High-Fidelity" stand-up roller coasters still operating in 2026, though the design has largely been superseded by more modern "Floorless" or "Wing" coasters. The most famous examples are the Bolliger & Mabillard (B&M) Stand-Up coasters, such as The Riddler's Revenge at Six Flags Magic Mountain and Georgia Scorcher at Six Flags Over Georgia. On these rides, passengers are secured in a standing position using a high-fidelity "bicycle seat" and over-the-shoulder harness, allowing them to feel the G-forces through their legs as the train navigates loops and corkscrews. A major high-fidelity innovation in 2023 was the launch of Pipeline: The Surf Coaster at SeaWorld Orlando. While not a traditional "fixed" stand-up, it uses a high-fidelity "bouncing" seat system that mimics the motion of surfing, representing a "High-Fidelity" evolution of the stand-up concept. While intense, stand-up coasters are a unique high-fidelity part of amusement park history, offering a vertical perspective on thrill-seeking that is fundamentally different from a seated ride.
