What is claimed is: 1. A folding electric bicycle comprising: a case having an open bottom and comprising a rear door and two widthwise spaced auxiliary wheels mounted proximate the rear end of the bottom; a manipulation assembly comprising a pivotal head tube disposed on the front end of the case,
What is claimed is: 1. A folding electric bicycle comprising: a case having an open bottom and comprising a rear door and two widthwise spaced auxiliary wheels mounted proximate the rear end of the bottom; a manipulation assembly comprising a pivotal head tube disposed on the front end of the case, two handlebars disposed on the top end of the head tube, a swivel fork telescopically connected to the head tube, and a front wheel rotatably mounted to the fork; a drive mechanism comprising a folding frame, a front chain wheel, left and right pedals connected to the front chain wheel, a rear bracket, a rear wheel rotatably connected to the rear bracket, first and second rear chain wheels coaxially connected to the rear wheel, and a main drive chain rotatably fitted around the front chain wheel and the first rear chain wheel; a brake; a seat tube secured to the frame; a seat post slidably secured to the seat tube; a seat disposed on the seat post; and power means secured to the folding frame and comprising a battery pack, a motor assembly including an electric motor powered by the battery pack to rotate the rear wheel, and a driven wheel operatively connected to both the electric motor and the second rear chain wheel, whereby for collapsing the folding electric bicycle, a driver detaches the seat post from the seat tube, folds the folding frame, places the folded folding frame, the seat tube, and the rear wheel in the case, turns the front wheel to be close to the auxiliary wheels, pushes the front wheel partially into the case until the front wheel is disposed in place, and closes the door. 2. The folding electric bicycle of claim 1, further comprising a lifting handle disposed on the top of the case. 3. The folding electric bicycle of claim 1, further comprising a foot rest slidably extending rearward from the bottom of the case. 4. The folding electric bicycle of claim 1, wherein the folding frame comprises a front section, an intermediate section, a rear section, a first pivot for pivotably connecting the front and intermediate sections together, and a second pivot for pivotably connecting the intermediate and rear sections together. 5. The folding electric bicycle of claim 1, wherein the battery pack is disposed in the case. 6. The folding electric bicycle of claim 1, further comprising an auxiliary drive chain rotatably fitted around the driven wheel and the second rear chain wheel. 7. The folding electric bicycle of claim 1, wherein the second rear chain wheel is in gear mesh with the driven wheel.
