Good purchase

The instructional manual sucks but son is a mechanical engineer and was able to put together without much trouble. No problem with starting but chain kept coming off and he was able to get it adjusted and running. The kids love it and have been riding with no problem. The electric start is the way to go. Overall I am satisfied.

Yes indeed, it's not really a manual, but more of a Parts Guide/Setup guide.
And yes, you need someone with mechanical skills to assemble a gokart..
There is also a Chain Setup guide for the Mini on our site with some very important steps you absolutely need.

Shipping trouble

DHL will drop it in front of your house if you aren’t home. Worst logistics team ever!

Great product

So far, the gocart has been great.
Heavy duty construction.
Runs good.
But please tune up your shipping company.
I was never contacted ahead of the company's shipment to my house.
I am not always at home, so a phone call from the transport company, telling me that you are in the road, in front of my house is unacceptable.
I am sometimes at work.
So this is not enough notice.
If my neighbor had not been home, then I assume you would have charged me for receiver.
Again unacceptable.
The was a great sale, product and comunication from the seller.
Shipping was not ok.

I bought this for my 5 yr old daughter. She loves it and rides daily. Governor easy to adjust to slow her down. Suspension is a little tight for the little ones. Only issue was the chain lost its mater link. So far so good. Electric start is the way to go !!

We bought this for my 5 1/2 yr old son at the end of March at the on set of COVID, because we knew he was going to need something to keep him occupied through the summer. He had a battery power tractor for about 2 yrs and had about worn it out so it was time to upgrade. I had been researching go karts and then saw the video for this one with the remote start and thought it was just right. At first I wanted to make him work for it so was going to get a manual start then thought about it and knew I was going to have to work for it and decided on the electric start. I was surprised at how quick it arrived, about a week from CA to VA. I got a buddy that works at a small engine shop to put it together for warranty but it wasn't anything I couldn't have done. The instructions weren't the best but with a little patience it came together. He left some play in the throttle so my son didn't get carried away until he had some practice, which took about two days then he asked me if I would build him a ramp. At first he couldn't quite reach the start button or get full throttle with the seat all the way forward which I liked because I didn't have to worry about him going too fast. With a little growth spurt he can now get in, strap in, helmet up and start it all by himself. It has been durable and we like the 5 point safety harness, he learned how to do donuts and ended up rolling it on it's side. No injuries and just scuffs on the paint, a little shock but was ready to get back in after about 20 minutes of relaxing. We are expecting to get about 5-7 yrs out of it before he out grows it, with it's adjustable seat and harness. It has plenty of power, carried me around the yard at 220 lbs, (head sticking out of the roll cage), but I believe it has power upgrades that it will probably get before he out grows it.
