The invention discloses a front shock absorber and an electric bicycle, and relates to the technical field of shock absorption. The front shock absorber comprises an outer cylinder and an inner cylinder inserted into the outer cylinder and slidably connected with the outer cylinder, the inner cylinder comprises an insertion end inserted into the outer cylinder and an exposed end used for being connected with a steering gear, the insertion end is provided with a first oil seal part, the exposed end is provided with a second oil seal part, and a guide rod is fixedly arranged at the closed end of the outer cylinder. The guide rod penetrates through the first oil sealing piece to be connected with a one-way damping valve arranged in the inner barrel, a damping spring is arranged between the one-way damping valve and the second oil sealing piece, a first cavity is formed between the one-way damping valve and the first oil sealing piece, and a second cavity is formed between the one-way damping valve and the second oil sealing piece. And hydraulic oil is arranged in the first cavity and the second cavity, so that the hydraulic oil is subjected to damping acting force generated by the one-way damping valve when flowing back to the second cavity from the first cavity. The arrangement form can be simplified, and the production cost is reduced.
