I have purchased 2 110cc 4wheelers for a christmas gifts for my twin 4 year old boys from Jeff at family go carts.com and they came not running for more than 2 minutes and then it would die! I contacted Jeff and told him my problems and he tried for me to fix both of them and take to a place to fixed! I said no he sent me a return slip from ups and then charged me 506$ for return shipping to pieces of junk and a180 $ for restocking fees !if anyone has had trouble with this company please contact me at [protected] mike Madison! Trying to get more people to join in on a multi person lawsuit so he can't ruin any more poor childrens christmas or birthdays!
