The Body Train XTI-1000 features a 9kg flywheel that is chain driven. The pedals come with straps & toe clips making it easier to build up speed using the ball of your foot, preventing calf & ankle straining. The resistance can be fine tuned using the dial system just like in your spin class, the adjuster also doubles up as an emergency stop. Keep track of your workout using the computer & scroll through the functions using the large single button choose to display Time, Speed, Distance, Pulse, Calories or Auto Scroll.
