We discuss an alternative neutralino dark matter (DM) direct detection in electron accelerators, that is, measurement of number of electron recoil events by neutralinos in halo. If selectron and neutralino masses are precisely measured in future collider experiments, the beam energy can be tuned so that the scatterings are dominated by the on-pole selectron exchange. We argue that if high current beams of O(100)A are available, the local DM density and velocity dispersion and DM wind due to a circular motion of the solar system may be measured when selectron and neutralino mass difference is O(10)%. This method is applicable to other DM candidates.
