Charles Guan, a young student at MIT, has built a Shopping Go-Kart that reaches a top speed of 30 miles per hour.

LOLriokart, the name Guan chose for his invention, was built using an ordinary shopping cart, discarded wheels and the engine from a high-performance golf-cart. Although he could have opted for a stronger engine that would have pushed the LOLriokart to a speed of 45 mph, he decided to go with a smaller one that allows him to switch between a walking pace speed and 30 mph.

The wacky kart features a custom steering system and because all components are positioned on the wheel line, it has a low center of gravity even when he’s inside. In case something goes wrong and the brake system fails, LOLriokart also has an emergency red button that cuts all power to the engine.

it may not met all safety regulations, but for one year’s work and a budget of just $300, LOLriokart is quite something. Well done sir!

Watch the road test at the bottom.
