Here are some fabrication pics of the motor mount. I brazed on 3/4 angle pieces for the motor mount and then covered w/ 26ga steel for a cover under the mount. i also placed 2 - 3/4 bars under the angles to the frame to stiffen things up. The Nirve frame was much beefier than a China schwinn and a Micargi that I have built on before. I feel the Nirve will certainly handle the stress.
