In the late 1960’s we were this close to motorcycling on the moon, which might be the most awesome thing you can do on two wheels.

Built as an alternate to the Lunar Rover (LRV), NASA wasn’t entirely confident that Boeing would have the LRV ready for the Apollo 15 mission, and explored using a two-wheeled vehicle instead for helping astronauts bound around in the Palus Putredinus.

As we know from history, the LRV was built in time for Apollo 15 and its subsequent missions, thus the Lunar Motorbike was never used.
