Great First Bike
It was a Christmas gift, and the child loved it. It was fairly easy to assemble. We had a blow out of the inner tube overnight, but the seller sent a new one right away.

Solid bike
Fairly easy to assemble although instructions were for multiple models so was a bit confusing. And you should be aware you will need an air pump because tires are not inflated. Past that it is good bike.
