Review Image by Absolutely terrible! The bike starts up but has NO POWER! it will not run under the weight of the bike itself. I have checked the spark plugs, air filter, carburetor, I’ve adjusted the throttle cable and the air flow screw to try and make it run with more power and nothing. I would not recommend this bike to ANYONE! I cannot ship it back fast enough. Also you cannot reach anyone by phone only by email. This is a terrible but DO NOT DO IT! Absolutely terrible!

THIS IS THE WORST BUY IVE EVER MADE ON AMAZON!!! Do not buy this bike!! I put it together, filled it up with the proper fuel and the bike cranked up immediately but it has NO POWER! Under the weight of the bike itself it has no pull, it barely inches. My son weights 70 lbs and the bike won’t move with him on it. I’ve looked at the air filter, adjusted the airflow screw, adjusted the idle, adjusted the throttle cable, checked the carburetor, checked chain tension. I’ve done everything to fine tune the bike and still no power! This is a horrible buy I wouldnt recommend this bike to anyone at all!! Do not waste your time with this purchase I will never buy another from here ever again. ... show more

    • No customer support
Color: Red
This things fires up easy and starts every time. But no matter how much throttle I give it, it won’t go forward. Fully automatic. Should be able to grab the throttle and go. There’s a lot to like about it, but there is no way to contact the seller to get support for this issue.

    • Horrible!!!!!!
Color: Red
Received with huge hole in box and swingarm was bent to hell making it not rideable. I have the old model Mototec demon so I switched swingarms just so my son could ride it. After starting it and warming it up it will not go full throttle, motor starts to die down. Adjusted idle and made sure my mix was right but still won’t run right. Biggest waste of money in my life!!! I spend thousands and thousands of dollars through Amazon every year and they just lost a wealthy customer. Won’t take return and won’t give me a refund. I’m done ... show more
