Re: folding motorized 26 inch mountain bike
just drain the carb,along with the fuel tank. I sometimes take 2 bikes with me in the car trunk.
remove the front wheel and if I need to remove the rear wheel. Most of the carbs have that sorry little drain screw on them.
It takes about 30 minutes to either put both together again or take them apart to travel.
So far no problems except the old lady doesn't like it when I take off on the bikes with my brother in law. We're gone most of the day out riding in the country in Mo.
