Here is a video and some pictures of another custom stupid-fat tire trail bike I am building out of a 1978 Honda ATC90. Converting an ATV to use electricity instead of a gas engine is labor-intensive, and you also have to consider the upfront cost of getting a brand new ATV, which isnt ideal. Greater stability and better cornering performance. We then reviewed the list of parts you'd need to make the conversion, and tallied up some ballpark costs if you purchased them used or from a junkyard. The trick was to have the front wheels tilt in parallel. No results found in this location. My EZGO 3 Wheeler to 4 Wheel Conversion Project Get latest price.
