If you’ve been looking for an activity that’ll let you “use your outdoor voice” when you’re done playing with your adult sippy cups and coloring books, you might want to consider Drift Trikes. Your “outdoor voice” in this case will mostly consist of screaming profanities in terror as you careen down a paved mountain road on a tricycle, but hey. You probably make the same sounds in your Prius during rush hour on a regular basis. Start saving your allowance now though; after your initial investment of 300 bucks for a Triad Underworld 2, you’ll need airfare to Taichung, Taiwan to tackle the downhill course featured in these videos. Wooden sandal brakes extra. For a mildly stomach-churning experience, be sure to also check out the 360 degree video further below.

The badass three-wheeled gangstas in the video above are probably using custom trikes, but you can get the Razor DXT Drift Trike pictured at the top, or the Triad Underworld 2  below on Amazon.
