Costzon Go Kart for Kids, 4 Wheel Off-Road Pedal Go Cart w/Adjustable Seat, Steering Wheel, 2 Safety Brakes, EVA Rubber Tires, Ride-On Toys for Boys & Girls, Outdoor Racer Ride On Pedal Car (Green)OEKO-TEX STANDARD 100

this looks awesome , great for the age designed.

The media could not be loaded. This Martin car is so much fun. My son loves to play with cars, so I chose this Martin car for him as a birthday gift. The car arrived very quickly and is easy to assemble. It is suitable for children aged three to eight. The seat is adjustable, the pedals are stable, and it has a handbrake. It is very safe to play with. Children like it very much!

Got this for my 5/6 yr old boys. They fit perfect, room to grow. They are small for their age, but should last a couple years.BLUF: Great product for a good price. Will fit most kids 4-7 maybe 8. Very easy for anyone to assemble, though actual instructions were horrible. Wheels are plastic with rubber tread over top, but have held up well with outside street riding. Smooth operation and the boys are having a lot of fun. I can recommend this as a good buy.-Watch the price! I looked at these one day for one price, they went up $10 the next day so I jumped on it, then they went back down 2 days later!-The instructions are horrible!!! Very hard to understand. I generally have a very mechanical mind and it definitely took me a few minutes to finally figure it out.-That said, once I did figure it out, they were very easy to assemble. Only took 15-20 mins. Anyone who can figure out the HOW can certainly accomplish the build.Again, I do recommend this product.

This is the most deceitful product I bought in a while first it only measures to about 33-34 inches which is significantly shorter than the 40 it claims!Furthermore, the instructions are so bad. You can’t see anything from the picture but overall this product is tiny. That’s why there is a two year-old in the photo. It says 5 to 8 years old impossible no American five yr old is gonna fit on this. Maybe if you got tiny kid, you’re OK but any regular American size kid will not fit on this!!Furthermore, this vehicle is only one wheel drive, so all the force is going through one wheel to push the entire vehicle very difficult to create momentum!

Super easy to assemble. It has a QR code to see the video for the instructions which helped a lot. My daughter loved it enough to personalize it with sticker and eager to learn how to ride it.

I bought two different karts at the same time, the Costzon Go Kart and the Hauck Hurricane. The Costzon was brand new, packaging was great, instructions were lacking as others have said. I actually had to rely on the completed photo of the kart in order to figure out what the dark photos in instruction book was referring to. I'm no mechanic mom, but I got assembly done in about 25 minutes. I thought it was a great little kart, until I opened my second package...The second kart I was to assemble was a Hauck Hurricane. This one was a bit more expensive but made for slightly bigger kids (4-8yrs) than the Costzon (3-5yrs). I got a Amazon warehouse item so I expected the box to be banged up, but I did not expect a used-in-the-muddy-backyard-then-disassembled-and-returned item. It literally had parts in a zip lock bag and no instruction pamphlet. I'm not even sure all the parts were there. I already told my kids I had a surprise for them so I couldn't just return it. I went ahead and assembled it, WITHOUT INSTRUCTIONS (just a youtube video of a different model).Despite all these set backs and what should've been the inferior model, I rode on both models myself (adult, 115lb) for a brief time (didn't want to risk breaking them) and found the Hauck to surprisingly be the winner. I'm no engineer, but it feels more stable, like maybe the rubber on the tires were actually absorbing some shock from our pavered yard. It has a WAY better turning radius to dodge all the furniture in the yard. This is the biggest reason I'm returning the Costzon. If you have a straight-away or limited turning area in which to ride, the Costzon should be fine. Perhaps to a 40lb child they won't feel the subjective "cheapness" of it. But to me, I'm going to return it while its still in saleable condition and getting another Hauck.Disclaimer, the Costzon was cheaper in price, so that may have a lot to do with quality. Can't say their other models are better or worse. Nobody asked or paid me to leave this review, just a unique time where I had two products at the same time and I'm able to conduct comparison!

So far solid products

Purchased for my grandsons birthday. It was a HUGE hit. It has been used daily. Originally I was concerned that the tires weren't inflatable rubber. I felt rubber would be a better choice. But seeing how he speeds like a maniac and cranks on the brakes it's obvious the very hard solid tires are a much better choice. The frame is metal and it's well made. Love that the seat is adjustable so it will last him several years.
