The FatMAC from em3ev has finally arrived in the US. We received our first one today. It looks to be a little over a pound heavier than the standard mac. The spacing is insane on this motor. It will easily fit a 205mm dropout with a few washers. The rotor mount is pretty far in from the dropout and on some installs you will need to install a rotor spacer and possibly space the caliper out towards the tire as well.
We will be installing this on a Mongoose Dolomite to have a showdown between the 12T mac and the BBS02. Stay tuned for more posts and general mayhem.
The Drive side can easily accept a 10 Speed Freewheel with room to spare.
You will need to use a rotor spacer and probably move the caliper out towards the tire as well.
You can order these from em3ev now the instructions on how are here (the motors are not on the website yet). Be aware that this is the Chinese New Year and the whole country shuts down for about a week and parties like crazy.
