Movement platform for bicycle trainer
A bicycle training system and methods of using the same. The system includes a movement platform that rests on a support surface and supports a bicycle in an upright manner with respect to the support surface. The movement platform includes a support frame having a base and at least one upstanding arm that supportably engages a portion of a frame of the bicycle, a resistance assembly operatively coupled to a portion of a drivetrain of the bicycle that applies varying levels of resistance to the portion of the drivetrain, and a plurality of bushings isolating the base from the support surface. The plurality of bushings are spherical thereby permitting the movement platform to move with respect to the support surface in response to forces applied to the bicycle frame during use of the bicycle training system.
