Bought this thing a couple of months ago. Immediately had problem getting to talk to technical support regarding assembling it. Got a friend to help and figured it out. Now throttle broke. I called and got a support guy who complained that they (saferWholesale) should not have sold me extended warranty because they don't sell it and have no parts. Asked what to do and he said he didn't know. I suggested sending me the throttle with the wires cut so I could splice it myself and that's what I had to do. It's working now but company won't give me money back for extended warranty even though they can't supply parts or fix it if something else breaks. Do yourself a favor and research before you buy things like this and whatever you do don't buy from SsaferWholsale, they are nothing but scam artist crooks. And don't even pay attention to their responses here that they will take care of it. They're liars and are full of crapola.
