  • Stay far away!
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. ... show more

  • Dirt bike review
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.

  • DO NOT BUY THIS BIKE!!!
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!

  • The small button on the handle bar must have the cover on it for the engine to start.
Color: Blue
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.

  • Zero torque
Color: Blue
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.
