For the past almost a year, I’ve been building a fully working, 1:1 scale Tune Thumper Bike from Mario Kart World!

The bike is fully functional. The cassette tape door is also a Nintendo switch 2 dock, so when you put the switch in and plug in hdmi to tv, it outputs without any other power source needed.

Specs:
~65mph stop speed
~70lb
Fully functioning buttons, speakers, lights, antenna, nintendo switch 2 dock
wood, aluminum,and a ton of 3d printing
