A zombie hunting moped? Seriously? But the product behind it is actually pretty sweet. A highly customizable moped with a 500-mile (805 km) range, 200 mpg (1.2 L/100km) efficiency and heavy-duty engineering. It easily converts to an ultralight dirtbike if you swap the 49cc stock engine for something larger, and its long travel suspension should make it pretty capable on dirt tracks.
Motoped makes a range of heavy-duty moped bikes that look great, get insane fuel economy and look like a stack of fun – particularly when you ditch the stock 49cc engine and stick a 155cc donk in there instead. With any horizontal Honda single cylinder engine, it's more or less a bolt-on conversion.
With a larger engine in, they look and perform like an ultralight dirt bike, although you'd probably be voiding your ability to legally ride them on the road. With 8 inches (20 cm) of suspension travel and decent DNM adjustable suspension, they should handle themselves pretty well off road.
