Question: gravel
Document: unfourtunately a part of the machine was broken, the part that goes from the wheel to the seat, my son in law went directly to Huffy for the replacement part, hopfully they will send it with no charge, and although the age is 5 years old, I think a height would help, because his legs are to short, or a set of blocks should accompany the green machine, just in case.
our pre-teen grandchildren love to do spinouts with the green machine. the big rubber front wheel, the plastic rear wheels, and rear steering seem to make this easy. the perfect graduation toy from a 'big wheel'...
now that these are back in the stores. I got this  ofr my sisters birthday and she is an adult. her and her kids had fun with this just like we used to when we were kids
had to go to hardware store to find a bolt as only one was shipped for attaching front wheel assembly. also, an out of alignment weld required me to use a large clamp to close flanges on differential to allow a bolt to be installed correctly. maybe, better QC at Hubby's Chhinese mfgh. location.
When it arrived everything was great, the big wheel was in it's original box and not damaged. It all worked just fine
We were so disappointed with the seat and suggest that the maker go back to the original seat design. We were pleased with how fast Amazon was able to get the machine to us.
We have an old green machine that our grandsons enjoyed so much that they eventually wore off the rear tires which we replaced. While the front wheel on the NEW green machine is awesome looking the SEAT on the old machine is superior. The seat on the new machine is built different and has only one bolt for adjusting. This was not adequate to adjust for our youngest grandson (who had been riding the OLD machine). This seat is also smaller and doesn't wrap around to give more protection and stability. I had read other reviews and took a chance and bought the new machine anyway because of how much the boys enjoyed the old green machine.
We found this at a great price and decided to go ahead and buy it for our 5 yr old boy. Too bad it is too big for him, even with the seat all the way forward. It'll just have to sit in the garage for a couple years until he can ride it.
We bought two of these last Christmas for our 10 year oldgrandsons. They loved them. The only problem is that theyare not well made and the flag on the back broke off the first day.This is a safety item that needs to be on the machine whenriding on the street. The boys loved them and couldstill use them, but they need to be a made a little sturdier.
We bought this for our 7 year old son for Xmas and tried to put it together the week before, only to find that parts were missing. The manufacturer did get the parts to us a couple days before Xmas. When we attempted to put it together we discovered that screws were missing. After a trip to Home Depot to find replacement screws, we were unable to keep the seat from sliding back and forth. Very frustrating!!!! Not to mention that the first time he rode it a metal piece broke off!
