We are going to build a stationary bicycle on a space stion. Well you might be wondering how were going to do that with no gravity. well we are going to use bulits to stay on the staitionary bicycle , and another idea we have is to use a trandemill but this is not your ordanery trandmill this trandmill well be able to stay in space. Were going to do this by boliting the trandmill to the space stione and for you to stay on the trandmill were going to use maginets you might be wonding why mightets well we are going to use mignets so you can stay on the trandmill but so you can pick your fought off as well so you can get the exarcise you need.
