My son loves his 4 wheeler

The order was delivered within a week. it had a few broken parts from shipping but the service department replaced each part with no hassle. I would buy another one in the future. I also love the safety features, kill switch hooked to a tether, a remote that can alarm and shut the wheeler off and turn it back on from 50 feet away.

My kid loves the quad.

Assembly was easy, however the fuel line keeps dropping off and will need some modification. I was in aware of the oil fill site glass until I removed the foot rest and saw it. This should be noted in the manual as I overfilled it accidentally and had to drain some out. Other then that my experience was good.

Good product

The atv showed up sooner than initially quoted. I did have to email in for the tracking information, but then found out it was being delivered that day. Assembly took about 30 minutes and the thing runs great. Both my 4 and 6 year old take turns riding it and the governor screw is super helpful. I plan on buying another one this fall, so the both have one.
