I changed a bunch of things today, like the fork, rear wheel, and driveline, so I could take the bike out for the first ride with the new extension. For using the absolute worst materials that seemed even remotely in the realm of probably working, it held up surprisingly well. I built this extension from 14 ga. hot rolled, galvanized sheet steel. The extension piece is still completely flat with very little structural integrity, and it was able to support my 210 lb body for almost half an hour, when I rode off a curb and folded the rear end. The Mk.II version will correct several fitment and structural integrity issues I've noticed, and also the design will change slightly, as the bike needs about 1/2" more ground clearance.
