BLK BOX's range of exercise fan bikes and air bikes covers everything from steady-state cardio to all-out interval efforts, including the Assault Air Bike and Wattbike Pro Trainer. Air bikes use fan resistance that scales directly with effort, so the harder you push, the more resistance the bike provides, making them well suited to both beginners pacing themselves and advanced athletes chasing maximal output.
Air bikes are a staple of HIIT and functional fitness programming because they engage both upper and lower body simultaneously, building conditioning faster than a bike that only works the legs. They're also low-impact, which makes them a practical option for athletes managing joint issues or returning from injury.
