- I built this Cyclekart a few years ago and was just wondering if anyone else on here has one. If you are not familiar with them you can type "Cyclekart" or "Cyclecart" into Google or YouTube and find a lot of information on them. The frame is built out of 1/16" wall 1"x 3" rectangular tubing, and the front axle is 1 1/2" Dia. 1/8" wall tubing. The engine is a Preditor 6.5hp. from HF. All the rest of the parts are pretty much go kart parts except the 17" Honda motorcycle wheels and the Amish buggy seat springs for the front leafs.
