Elliott's tricycle is made by Giant. They also make adult mountain bikes. It might be more than you want to spend but has never rusted, still works great and we still use it almost daily. It is now used for Allison, but Elliott will still stand on the back and ride down the hill. Definitely worth the extra money.
I recommend going to your local bike shop and ordering a tricycle from a company that specializes in making bicycles. Most "adult" bicycle companies like Giant, Cannondale, Trek, Specialized, etc. all make tricycles and children's bikes. They will last through several kids! I know one Specialized kid's bike that is on its 4th kid and still works great. Plus, it will be put together by a mechanic that specializes in building bicycles. W*lmart/D*cks/T*rget bikes are usually put together incorrectly by someone that does not have the knowledge to do it correctly.
If you are in Kennesaw, I reccomend https://freeflite.com/ in Marietta off of Canton Hwy. and https://www.outspokinbikes.com/site/default.aspx in downtown Woodstock. Both are very reputable shops.
I also recommend the Kettler tricycle. We have one that we have used for our 3 year old and it's held up great. Our almost 2 year old will be using it soon.
They can be pricey especially when you have to buy 2--we bought ours in almost new condition off of craigslist.
