Stay fit all year long from the comfort of your own home with an indoor bike trainer. Indoor trainers are a convenient option when you're short of time, or if it's too cold, wet or dark to ride outdoors. Wheel on trainers are a great portable option which can be easily moved around and folded away. My Ride's wheel on indoor trainers allow you to quickly install a range of bikes with wheels ranging in size from 26" to 29", as well as 700c road wheels.
