This self-powered stationary bike uses a magnetic resistance system that converts pedaling into energy, requiring no electrical outlet or battery replacements. It supports up to 350 lbs with a reinforced steel frame. The precise magnetic resistance can be adjusted manually or automatically to match expert courses via app sync. An ultra-heavy flywheel provides smooth, consistent resistance for weight loss, muscle toning, or overall fitness. Connect to the MERACH app to track resistance level, distance, time, and calories in real time, with data sync to Google Fit and Apple Health. The advanced silent magnetic resistance system operates below 25 dB for quiet home use, allowing exercise anytime without disturbing others.
