Due to shipping safety, we cannot do 100% fully assembly on most of items.
Mirrors, battery set up, handlebar and other minor adjustments are required. Be sure to tighten all screws, check for appropriate levels of engine fluid and fully charge battery prior to operation. Warranty is valid straight from the box.
For go karts, you will need to install rolling cage, steering wheels, and connect battery. Some models (small to middel size) may require slide seats and hook gas tank.
For bikes if shipped in crate, you may need to assemble (not exactly same on every models):
Handle bars, front fender, front wheel , speedometer sensor, mirrors, battery, headlight and turn signals.
