I built this drift trike/go-kart out of an old BMX frame and a 6.5HP lawnmower engine. Then I got some PVC pipe sleeves to fit over the tires and drifted it around every corner in my neighborhood.Â
Sadly, it no longer exists.
Before electric bikes were really popular, I found a conversion kit online and learned how to weld in order to build this 3-wheeled go kart. It uses 3 car batteries and for a long time didn't have brakes (I eventually put some on the rear wheel). The racing seat was the coolest part of the whole thing.
Sadly, it also no longer exists.
