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

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.

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.

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.

Can't get the engine to run with the choke fully open. Assembly was pretty easy. Decals were the hardest part. Will be great fun for great grandchildren.

Bike came very fast and wasn’t to hard to put together my son loves it

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

Its ok if you want your kid to get bored with it right away. There is zero torque It will go 25 ish mph or little more but it will take you 3 city blocks to get to that speed.

Worst purchase ever, says max rider weight 150 lbs, my 80lb son got on it went to go and wouldn't move clutch started pouring out smoke. So figure to big so ga e it to youngest bot who is small for age and ways 45lbs, got on it and went full throttle barely moved finally got it moving after pushing it took forever to get to a rideable speed. So now after being rode twice it sits in a shed.
