Model No.: WM-T002 This three wheel electric mobility scooter is new model developed based on the small model. Some client feedback that the outstanding of the battery box is not kind especially for the seniors and disabled persons. Another point is the rear wheel of the small model is WM-T001 is too small and not good for some bad condition terrains. Combine all the feedback from market, we developed the second three wheel electric mobility scooter, with big size and flat fooddeck to put battery under it, and it is with 12inch rear wheels which give much better crossing performance on poor road conditions.
