SportCrafters trike trainers are the only trainers in the world specifically designed for recumbent trikes. Easy to use, lightweight and portable, our trike trainers do not require any assembly or maintenance. The OverDrive Trike Trainer automatically adjusts in resistance as the rider changes speed – no manual adjustment necessary. In higher speeds, the OverDrive Trike Trainer will ramp up the resistance to realistically mimic road riding conditions. This trainer is perfect for the active trike customer who wants to maintain fitness while riding indoors.
