Building a Pit Bike in 33 Minutes

Built a pit bike in my garage using a 125cc, air-cooled, 4-speed manual lifan engine that theoretically puts out 8.5 kW. All of the parts I used for the bike were purchased from eBay, including the engine. The bike can reach around 50 mph with the 37T sprocket I have at the moment.
