Based on a digital rendering by Andrew Fabishevskiy, motorcycle design company Hookie Co. built a real-life prototype of an electric motorcycle designed to be driven on the Moon. Named Tardigrade after the hearty micro-animal, the 2-wheeled rover weighs almost 300 pounds, is constructed out of aluminum, Kevlar, carbon fiber, and other materials, has a top speed of 9 mph, and a battery with a range of 62 miles. You can check out how it was built in this video. I want one! Electric motocross on the Moon does sound pretty fun:
Regarding flat track racing on the moon, I would prefer some big gaps and jumps more than turning left around an oval. With almost one-sixth of Earth's gravity, I'd need only a small bump to jump 10 meters — that would be fun! Maybe the Tardigrade inspires space-addicted people and engineers for upcoming lunar missions, and I would be more than happy to be a tiny part of that.
