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

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.

Love it

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!

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.

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.

Other than the motor mount cracking and falling off its a ok bike im just gonna put a rotary on it and call it a day also speed on this can very mine when tuned right hit 39mph and im 5,7 155lbs

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.

STAY AWAY! I have owned/built/repaired more mini bikes than I can count. I have been a motorcycle mechanic for over 20 years and have never seen such junk. Won't even make it up the slightest incline with my kid on it. Every 50cc engine I have ever had in a bike 2stroke or 4stroke had been able to ride me around no problem and would fly with my kid on them. This engine is week and has several design flaws from the clutch strings being to week to actually engage to the exhaust pipe being a generator exhaust and blowing directly onto the front tire. Stay far away spend a couple hundred more and get a name brand. Not worth even half they money they are charging, not very sturdy at all and will just leave you and your kid disappointed and maybe even injured.
