I have this DIYe kit that I got for free not too long ago. http://www.diyeboard.com/36-dual-motor-6-wheels-allterrian-electric-skateboard-10s5p-p-596.html
I have heard Torqueboard upgrades such as the trucks, motor mounts, and motors would work but I am not at all sure where to start. Any advice? Also I have the street wheel kit and I prefer riding with that to the AT wheels.
