MotoTec Thunder 50cc 2-Stroke Kids Gas Dirt Bike 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.

Spits sparks out of the exhaust that is pointed at the front tire. Already burnt up two clutches with a 40 lb kid on it. Won’t even pull him up a hill. There are no returns on this item so think really hard before you buy

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.

Overall it’s decent lil slower than expected. And it’s very very narrow is the major complaint I’d say. Other than that it’s not a bad purchase for the price.

Product is defective. It starts the engine sound fine.but it doesn't accelerate .I feel ripped off.dont purchase this product. They don't give refunds. Iam done using Amazon.

This bike is very fast and good for a 12 to 16 years old. But the bad part is its hard to pull start

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

I did not like this off road bike at all it was hard to start, it took a long time for this bike to operate and the exhust fumes was bad I would not purchase another off road 50c bike again.
