Patent attributes
A foldable exercise bike includes a cross configuration formed by a main frame with a treading-driven rotation mechanism at bottom and a seat at top and a second frame with a pivoting portion pivoted to a handle. The main frame has a first-positioning device, and one end of the first-positioning device is selectively fixed on the second frame, so that the main frame can be fixed with the second frame. The second frame has a second-positioning device, and one end of the second-positioning device is selectively fixed on the handle, so that the second frame can be fixed with the handle. A resistance device is between the second frame and handle. The length of the resistance device can be changed when the handle is swung relative to the second frame, thereby generating a resistance force opposing to the swing motion of the handle.
