STEPR BIONIC BIKE XL VPR™

The STEPR BIONIC BIKE XL takes the traditional air bike and pushes it forward with VPR™ technology and refined ergonomics. Built to adapt to athlete size, strength, and intent, it delivers smooth, scalable resistance for everything from rehab work to max-effort conditioning. The result is a bike that responds instantly to output and supports true total-body training. At the core of the BIONIC BIKE XL is VPR™, a patented air-resistance system that provides over 100 virtual levels of load in real time. Resistance scales naturally with effort, allowing athletes to move seamlessly between low-cadence strength endurance, steady aerobic work, and high-intensity sprint intervals. From exceptionally light resistance to heavy, grinding output, the load meets the athlete without manual adjustments.
