Overview
The Elite RB X is a recumbent exercise bike built to a compact 49-inch length so it fits into smaller rooms than most recumbents, with a seat that adjusts across 5 tilt positions and 25 forward-back positions. It supports riders up to 350 pounds and connects to third-party fitness apps over Bluetooth FTMS.
3G Cardio positions this as commercial-grade equipment sold direct rather than through a gym, backed by a lifetime frame warranty and included in-home labor for the first year. The shorter overall length compared to typical recumbents is the main differentiator, along with a low step-through frame for easier mounting.
