Fast Mini Quad Bike Build Project + Track Speed Test

This is my mini quad bike that I have spent dozens of hours putting together and building and finally got a chance to test it on a go kart track and the thing flys. This has a 39cc 2 stroke engine with a 15mm carb. This is as far as I can see the fastest of it's kind. I managed to reach a speed of around 40+ mph and it's great fun to ride too. Be sure to subscribe for more fun stuff that we build.
Another great youtube channel is Colin Murze, in fact after watching Colin for a couple of years it gave me the idea to start a channel of my own building fun stuff so here we are. Colin built a very cool bumper car which you can see here - • World's Fastest Bumper...
It's very fast and it looks great fun. I may even build one of these myself one day too. :-)
