I have one that I built it is pretty custom, it has a front motor and a rear one which makes it an all wheel drive, it has two batteries that I can either set for extra power or extra range. I have it set up as a motorcycle throttle for the rear motor and a thumb throtle "ATV style" for the front motor, it really comes in handy when you hit loose sand or gravel and hills and also saved me from taking a dive when you are sliding or skiding or about to take a fall it pulls you back into control. It has a 60 mile range and does 40 MPH I use it to go further into the woods than I ever thought possible which has really expanded my horizions.Plus you gotta love those fat 4.5 inch tires that and a cushy seat and I am all set to go.
