I purchased this black mini dirt bike for my 13-year-old son, and he absolutely loves it! From the sleek design to the solid performance, this bike has exceeded all our expectations. The 99CC 4-stroke engine provides just the right amount of power, and with a top speed of 28 mph, it’s perfect for him to enjoy safely while having a blast. The bike is incredibly sturdy, with a durable build that easily supports his weight. It’s the ideal size for him, and he’s been riding it every chance he gets. Assembly was simple, and the engine started up without any hassle. It’s also very fuel-efficient, which is a nice bonus. This bike is an excellent choice for kids or teens who want a reliable and fun ride. Seeing my son’s excitement and happiness when he’s out riding makes this purchase one of the best decisions I’ve made! Highly recommended!

Excellent mini bike for younger riders. We have a very tall 8 year old (4’6”) that loves this mini bike. We purchased this bike so he could get familiar with riding and it’s been perfect. Very easy to assemble and maintain. Runs very well and have had zero issues. Just make sure to change the oil in accordance to the manual and this bike will run smoothly.

This is a good bike, but it is very small. I should have checked dimensions of it, as I was expecting a larger bike. I would say it is a better size for a 7 or 8 year old, but my 10 year old was happy to get it and has been riding it almost nonstop. He is 5'3 and 110 lbs. I can ride it too and I am 5'8 155 lbs., just not very comfortably. It doesnt go super fast, which i like, but probably could if you had it on a road or concrete. We drive it around the yard with no problems. The string to start it did break on the first day, but we got it fixed and are satisfied. Overall recommend, but check the size. None of the things that came with it fit my 10 year old. The gloves and pads were all too small.

10 out of 10 for this product! My son is thrilled with his motorcycle; it’s very fuel-efficient and excellent quality—100% recommended. I have a 7-year-old, and I won't hesitate to buy another one for him.

The motorbike truly sucked! I purchased for my 13 year olds birthday. For one.. if your buying this bike for anyone over the age of 9, change your mind now its so tiny and doesn't get up and go well not much power. Since there were other teens on reviews thought itd be fine for mine. It's literally built for a 6 year old. Besides that, the item came with damaged back tire which was terrible because I opened it the day before her birthday to put it together. Customer service was a complete let down they took a whole day to write back a sentence that didn't help me move forwardwith the return. It took 3 weeks to get a refund in the form of check, which I still haven't received. If you plan on buying this make sure there's a mechanic in the family and your child is small. Don't waste your time the whole ordeal was more frustrating pick a different bike.

Our 11 year old son loves it. It has a decent top speed, good acceleration. it was super easy to put together and has no issue firing it up. Little tricky to get oil in, but came ready besides gas. small gas tank so if they ride all day they'll need to fill up, but overall great value for the money. And you can get replacement parts if needed instead of just having to throw the whole thing for scrap, so with good TLC should last. Kid can start it up easy, too, but the first few times learning how to use the choke might be a good lesson.

In general this is a cool, relatively inexpensive way to get younger kids started with motors and bikes. The problem with this is in the engine design. The gearbox is connected to the motor by a thin metal cup which looks like aluminum. The cup breaks and the engine runs without driving the rear wheel, so it doesn't move. The first time it broke was 2 weeks after we purchased it. It was covered under warranty so they replaced it without charge. After it sat inside of a heated garage for winter, it broke again this spring. Because it is outside the two month warranty window, you have to buy a new gearbox from the FRP website. $30 isn't ridiculous, but if they would just fix the design of the gearbox, it would not be an issue. My kids love their bikes, but having to replace the gearbox every 4-6 engine hours is a little excessive.

I purchased this for my 4 year old daughter for Christmas. I was expecting her to not be able to handle the weight of the bike very well at first. This bike was delivered quickly, extremely easy to put together and fired right up the first time I turned it on. She of course was extremely happy, and handled this bike easily. Its alot of fun to use, extremely safe for the little ones and absolutely the cutest bike ever! I highly recommend anyone to purchase this bike for their kiddos!
