  • Worth the money
Color: Green
Bought this last Christmas for my then 9 year old. He wanted an actual dirtbike but 1) had never drove a dirtbike at all and 2) i don't have real, full size dirt bike money šŸ˜‚. Anyway, we're coming up on a year later and he still enjoys the thing. No major problems and by that I mean his chain has currently fallen off. That's it. I do remember seeing some reviews about it being too small for some peoples kids. I will say my kid is sort of small for his age. It's like perfect size for him. But my oldest who was 12 at the time, he was too big for it. He's tall and lanky though. His knee hit his elbow while trying to ride it and he fell. He's also just not really into this kind of stuff so šŸ¤·šŸ¼ā™€ļø. All in all, the thing is still generally running fine a year later. The kid it was bought for still loves it and uses it often enough. I'm happy with the purchase and outcome, so I'd say money well spent. Hoping I get maybe another year or so before I have to upgrade him! ... show more

  • Great for my 4-5 year old!
Love the low seat height, light weight, and overall design. This is a simple machine that is perfect for kids getting started! My 4 year old was very comfortable & well-balanced on a pedal bike, and was dying for a dirt bike on his 5th birthday. We ordered/gifted it a bit early due to COVID-19 stay-at-home orders, and none of us were disappointed. PRO: + Plastic engine cover/guard to prevent burns from tip-overs + 4-stroke engine + Fully automatic for kids + Easy 1-2 pull start (nearly every time) + Low seat height + Lightweight + Very easy to assemble + Simple, secure packaging (product arrived without damage) + Safe throttle response/power band CON: - Hard-to-reach brake levers for little hands - Lever-only braking (the previous issue could be alleviated with pedal rear break) - Strange mounting position for front fender - No adjustment possible on throttle - No remote or tip-over shutoff, but can't complain at the pricepoint I'd buy this again in a heartbeat! ... show more

  • Mechanic’s Take
Color: Pink
Assembly of the bike was pretty easy. I used the tools it came with, even though using my own would have been easier just to see if it was possible. I read reviews that said the front fender breaks off and I can see why this would be true. The fender catches on the engine guard at full lock of turn. I removed the fender and trimmed it on a belt sander (could use scissors but wouldn’t look as nice and have some sharp edges) to prevent it from rubbing. There’s lots of suspension travel and it cranks easy. I recommend running only ethanol free gas in any small engine and when it goes for long periods of disuse. Drain the fuel and then let it run until the carburetor is dry. Can just flip the bike over and dump it from the fuel tank, just allow it to sit upright for a while before cranking. The chain issues reported also seem to be non-event. If you are competent enough to adjust the chain then you will have no problems. The instructions do not say to do it but anyone with a few brain cells can determine it is too loose. The kill switch wiring has very minimal weather protection and can dangle too low, put electrical tape on the connections and then zip tie the slack to the frame so your young one does not have any issues. Bike runs good and I’m sure it will for a long time if you do annual oil changes (which it takes a little more than they say) and run good gas in it. Overall a great bike for 300+ shipping ... show more

  • Nice little bike for the price
The media could not be loaded. Assembly was pretty straight forward. Seems like a well built little unit. Starts up very easy. Has a nice amount of pep to keep things interesting for my child. Makes a nice noise but not loud enough to annoy the neighbors. With only a short time of riding I highly recommend. Will update as reliability is proven. ... show more

  • 25mph little bike is perfect for a first bike. Sells great to boot
Color: Green
Update: just one of the update everybody we were missing the parts on this dirt bike when it arrived and contacted the seller about 5 days later they arrived as well as a few extra odds and ends. After getting it all together for my son to write it it is everything he wanted. A consideration for parents this thing is quicker than you think it'll be. I hopped in the Harley and paste my son and my 9-year-old was doing 25 mph on the darn thing it was amazing. The quality of the parts the plastics the decals are all outstanding for the price point. The brakes are a little underpowered and rinky dinky but do the job. I might replace them in the future we will see all in all I would recommend to any of my friends and family this bike and the seller in particular we are thrilled with them thank you so much old post:Arrived missing parts and the box was soaked with oil presumably from the motor. Order this for my son's birthday when it arrived The box of saturated with oil and parts were missing from the box. I will update this review upon the conclusion of getting my issues resolved. ... show more

  • If you’re on the fence… here’s your sign to buy it
The media could not be loaded. My son is 10, a little small for his age, and he’s been able to ride one of those cheap Razor electric bikes that go about 5-6 mph and so this was his Christmas gift, and his first real experience at a gas powered dirt bike. I assembled it in about 30 minutes with the tools provided, and boy has it kept a smile on his face for days. It’s been the best $400ish I spent (with shipping and all included) and it’s definitely something I was 50/50 on, but after seeing how cool it’s been, I’m already looking to buy a bigger one for myself. It rips around in anything you ask it to, it goes pretty quick with him on it, and I’m a little over 200 lbs and it will rip around a bit with just me on there as well. It’s a blast and I hope this is your sign to buy it. Such an awesome little bike for the price. 10/10 would recommend! ... show more
