Ultra fast ultra light mid drive

[Teramax]

My new mid drive. Modified Astro. CNC 7075T6 chassis. Enclosed oil bath primary chain, o-ring secondary chain. Motor and chassis total weight less than GNG motor alone.

Wheely control, traction control, auto (pwr/eco) and manual gear change modes (70ms per change - cuts power to motor so can change with full throttle). 21kg.
