I forgot to mention that my kids don't shift much. ever since they got gears I've been coaching them on cadence etc but they really like to pick a gear and stay there. They are getting better but really they don't have much need to shift on paved trails as I do out on the street.

That's a sweet looking little road bike. I wound up getting my kids better tires with less rolling resistance cuz they didn't need full out MTB tires. I got them BMX tires and also a set for my MTB so we would all have the same. MAXXIS Holy Rollers were fun for the years they used their 24" bikes.
