Alien Power System has developed a motor for the Eone. It is a modified version of the well known 12090/S motor. It has a 12 mm shaft instead of the standard 10 mm shaft. The shaft is shortened so the 60 mm Eone pulley fits without any DIY modifications. The ball bearings are also improved. This modified motor can be purchased from G-air or from Alien Power Systems. If you buy a complete Eone kit, it is this motor that comes with the kit.
