I bought one of your mini cobra four wheeler bikes and it took 2 hours to start up the first time then it refused to start again. I tried putting new gas in. In addition to that the four wheeler came and was all scratched up.  I had the mixtures of gas and oil right and it wouldn't work.  I finally got it to work after lots of work then it would just randomly stop running every few minutes.  This four wheeler has a horrible quality and the only thing you told me was that you would send me a new part. After I installed the new part it still didn't work. I tried to get a refund and you said no even though it was still under the 60 day warranty. After i told you this you said that after i put gas it the four wheeler it couldnt be returned. This is outrageously stupid the way you did business with me and I will make sure that no one that I know buys a bike from your company and I will write bad reviews about this product and this company.
