    • Nice little dirt bike! Nice little dirt bike!

The bike was delivered quickly, and came in perfect condition, everything was as described in the seller's add. Partial assembly is required (you need to bolt on the rear shock, handlebar, front wheel, &attach front brake). Takes a half hour to an hour to complete everything correctly. Use loctite, check over all the nuts and bolts--things will need tightening. Carburetor may need minor adjustment to idle properly (very easy to perform with a flathead screwdriver). Came with necessary tools, an owners manual, fuel mixing container, decals and a title. I mixed the fuel &oil 25:1, tightened the spark plug, and fired it up. I weigh 150 lbs and it carries me with ease, the seat is fairly comfortable as well which was a concern of mine. I installed a $15 set of handlebar risers so the bars would clear my knees when turning (I'm 5'7), and now the bike is comfortable for me to drive. Runs &drives great &is pretty peppy! I'm very happy with this purchase! *Update: This bike continues to impress. Starts first pull every time, after 3 tanks of gas, some dirt road driving, wheelie pulling, and small jump hitting, it runs like a top. A fun, affordable, pit bike with possibilities. I've installed some taller, wider, aftermarket handlebars &grips, which were an easy install. Bike is easy to work on. I'm having fun with it! ... show more

    • Don’t buy unless you know how to fix it!
Color: green
What an utter disappointment, DO NOT BUY if you aren’t mechanically inclined. Put the bike together, it cranked and ran fine 2 days before Christmas. Gave it to my son on Christmas morning and it would not start or run. After an hour of working on it, we finally got it to start again, but it doesn’t run completely sound. Don’t buy this as a surprise or present for a child and expect it to instantly be ridden. ... show more

    • NOT a motorcycle just an expensive CHEAP chainsaw motor on wheels
Color: Blue
First, sorry this is so long. Second, I am not one to write reviews but I am so disgusted with my purchase of this bike. This motorcycle is very very low quality dirt bike/motorcycle. Actually, after owning numerous name brand dirt bikes and motorcycles, this SHOULD NOT be classified as a “motorcycle” or “dirt bike”. This should be classified as an over priced CHEAP toy. After Amazon passed me back onto the seller, the seller said “oh you opened it and now we can’t return it”. I’m thinking how in the world am I supposed to see if it’s worth anything if I don’t open it and use it. I see a lot of these used bikes forsale online sites because they are junk. Shame on me for buying it especially after I have owned brand named bikes for years. I guess I lost $400 plus dollars since the seller is saying I have to pay for parts like the carburetor that doesn’t work after one ride by my grandson and also the pull start broke. I also paid a professional mechanic to try and fix it. He got it running but then that’s when the pull start broke. So now I’m $75 on top of the $400 plus so I’m out around $525 with a broken junk bike at my house. I decided to just go purchase my grandson a Suzuki 70cc so he can ride with me. Maybe I’ll take my tractor and crush this cheap bike and use it for scrape metal to recoup $20 out of it or use the motor as a weed eater motor, that is if it’s strong enough. Hopefully Amazon helps me get a refund since I and my business spend thousands of dollars a month through them. ... show more

    • Better than bad. Better than bad.

Review Image by Jack
Got it for my 8yr old daughter and she loves it. It'll definitely be too small by next year though. The build quality is as you would expect with something this inexpensive. I can hold the front tire between my ankles and still turn the handle bars at least a few inches, but it hasn't seemed to phase my kiddo. And after a couple weeks, I've needed to go through and tighten many bolts and screws. It also uses a gas/oil mixture ratio of 25:1. Not sure why, that's twice as much oil as a normal two stroke motor. There are no gears. Its a clutch based drive system. That's great for a kid to learn on, but it has its disadvantages too. For example, I went for a hike and my daughter rode with me up the trail. As the bike got hot, so did the clutch. As a result, it wouldn't carry her up the hill under its own power even at full throttle. I had to push her the rest of the way & then let the bike cool down before continuing. All that said, she still loves it, I'm happy with that, and I have no regrets buying it. ... show more

    • Very happy with purchasing
Color: White
Excellent beginner bike.at a great cost.for the money you can’t go wrong all parts for these are cheap and super easy to find.Our son loves his as he is 7.let’s him figure out the balance maneuverability braking/Throttle control,before we throw in clutching shifting foot an hand control along with all the other dynamics of riding.And if they don’t like and dirt biking is not for them then your not out a lot of money as like the other name brand companies.It’s an excellent purchase would highly recommend it to anyone who wants to introduce kids to the motocross world. ... show more

    • Very happy until
Color: Blue
I bought two of these for my boys same brand just different colors. Two days after buying them one of the started leaking gas! You could fill it up and over half of it would drain through the hose so couldn’t even put a full tank of gas in. Later the bolts started coming off had to replace them. Now both dirt bikes have been parked because the chain came off one and the other one just won’t start at all. Definitely do not recommend due to the fact that it’s not worth the money because you pay more trying to fix the things ... show more

    • Great learning bike daughter loves it
Color: green
There’s not many reviews I’ve found for this but at this price it is a great learning bike for kids between 6 -10 years old. Easy to assemble comes with gas mixing tank so you know exactly the right amount of gas and oil to mix. Starts right up every time on the first pull. My 7 yr old daughter loves this and rides it daily for hours. ... show more
