The XTERRA SB550 Recumbent Bike was developed with one standard in mind – to hold up to the abuse of the athletes it was named after. With the XTERRA status comes our seal of approval with an impressive lifetime frame and brake warranty, 3 years on parts and 1 year in-home labor. Specifically designed for the home environment, the SB550 incorporates numerous thoughtful features that were developed with your performance and comfort in mind. The SB550 Recumbent Bike is perfect for anyone regardless of age or ability. The walk-through frame design, large mesh back seat, smooth friction-free drive system, and large blue backlit LCD display all contribute to an exceptional ride experience. Add to that our heart rate control programs with wireless heart rate monitor and an easy-adjust slide rail, and you have the ultimate recumbent bike.
