Was really interested in 48 v Mac12t front motor last fall. Now have 4 bafang 500 w 36 v used geared hub motors & 2 40 v 20 ah LiFePo4 batteries. Thanks anyway. word "cutler mac" sure makes bing perform better with results. "Mac12t bicycle motor" mostly found me ads for apple macintosh parts plus the one allibaba ad for pallets of Macs FOB Shanghai. Wasn't sure that ad was even the same company.
