  • DO NOT BUY THIS BIKE!!!
Color: Red
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
Reviewed in the United States on December 31, 2024 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!

Packed nicely. Surprisingly shipping was faster than expected. As a beginner dirt bike this is perfect. It’s been a bit over a month and don’t have any issues.

  • Don't waste your money or time!!
Color: Green
The media could not be loaded. I wish I didn't even have to put a star up here to write a review, absolutely a horrible buy. Don't waste your time. It's super tiny, they don't represent it right, it came fast but when we put it together as instructed and with our own prior mechanic knowledge, it does not work, the clutch will not engage at all. It will only engage when the bike is lifted off the ground. Standing beside it full throttle open and it wouldn't go anywhere!! Video posted , sorry about the quality of the video! ... show more

Overall good starter bike if your looking to purchase this bike please make sure you get a new spark plug , carburetor and clutch and make sure to tune it up there is a bunch of videos on YouTube. Overall it runs good and you can't beat it for the price.

  • 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
