The invention relates to a novel electric tricycle frame. The novel electric tricycle frame comprises a U-shaped main framework (12) formed by bending one pipe, bent portions are formed in the middle of the main framework (12) in a compression mode, the main framework (12) is divided into a front framework body and rear framework bodies, and the front framework body is lower than the rear framework bodies in the vertical direction, so that a step shape is formed. A tail crossbeam (2) is erected between the tail ends of the rear framework bodies in a fixedly connected mode, and a first middle crossbeam (4) is erected between the middles of the rear framework bodies in a fixedly connected mode. The novel electric tricycle frame further comprises a main crossbeam (6) formed by bending one pipe, the middle of the main crossbeam (6) is located in the front framework body of the main framework (12) and fixedly connected with the front framework body of the main framework (12) through a head crossbeam (14), the rear end of the main crossbeam (6) is bent upwards and fixedly connected with the middle of the first middle crossbeam (4), the front end of the main crossbeam (6) is bent and extends obliquely, forwards and upwards to form a front oblique beam, and the top end of the front oblique beam is fixedly connected with a front forked pipe (10).
