For those who loathe transferring their bike on and off the stationary trainer but love incorporating a good indoor session, even in the summer months, there's now a burgeoning market sector offering indoor-specific bike frames to be used in conjunction with a trainer as a more economical option to full bore smart bikes or stationary bikes
