Despite the space-saving design, the 400XL is plenty powerful, with a precision-balanced flywheel and a quiet V-belt double-drive transmission system. The bike also includes an eight-level magnetic tension control system so you can find the right resistance for your training goals. It's easy to monitor your workout progress via the easy-to-read LCD display, which tracks your distance, calories burned, time, speed, scan, and heart rate. Best of all for frequent exercisers, the 400XL's semi-recumbent design is inviting and comfortable, making it ideal for people who dislike upright-style bikes or who are recovering from injury. Add in a large seat cushion and backrest and you have a great bike for riders of any size and body type.
Other details include extendable leg stabilizers; a hand pulse sensor for reading your heart rate; a three-piece, high-torque crank system that provides a smooth, consistent pedaling motion; large pedals with safety straps; and transport wheels for mobility.
