Actually the motorbrake continues to freewheel due to a bug in the Tacx Trainer Software. With the older Fortius, iGenius/Genius SMART, and Vortex/Vortex, if the rider stops pedaling for more than a few seconds, the motorbrake stops SMART, but is not the case for the Neo. According to Tacx, this issue is slated to be fixed in the next update that should be released within a few days and currently the only workarounds are to wait for a flat area to coast to a stop or unplug the Neo.
