A second battery is a second price. The guide checks Engwe and Fiido on November 2, 2026. The M20 3.0 dual battery prints 2,400Wh and a spec line of 180 miles for the two-battery version. The T3 Max dual is 1,620Wh. The M20 2.0 dual leaves range blank. The $2,299 T3 Max is one battery.
The single-battery M20, and the 40 mph off-road line, are the moped-style guide.
The T3 Max rack split on the standard pack is the cargo guide.
