You may have seen my ride on other posts from znsanerydr. I finally got my internet hooked up. I have a green cargo trailer for my mountain bike with a 2.5 horse 4 stroke. My trailer will haul over 100lbs at 135mpg averaging 26 miles per hour in town, but I top out at about 40-43 mph. This was before I broke the keyway out of my hillard clutch, now I'm buying a maxtourque clutch with more set screws in it.
