Getting your kids the right size bike is important and, fortunately, also easy. You just need two pieces of information about your little rider:
Have the rider stand against a wall, hold a book between their legs so that it is firmly against their crotch (the same place their bicycle seat will be).
Measure the distance from the floor to the top of the book.
Children who are learning are more sensitive to bicycle height than children who already know how to ride a bike. For this reason, our recommendations for bicycle sizing vary slightly based on the experience lever of the rider. The chart below takes into account the fact that experienced riders tend to adapt better to a bike that is slightly larger. For this purpose we categorize young riders as either "Learners" or "Pedalers"
Learner: riders who either have not yet learned to ride a pedal bike, or are still frequently putting their feet on the ground while riding.
Pedaler: riders who can ride confidently and only put their feet down to stop.
The Prevelo Zulu One packs high performance mountain bike features into a tiny 14-inch wheel size package. Every component is the real deal and is carefully chosen to provide the best performance and fit for young riders ready to tear up the trails. It features:

I bought this for my son to upgrade from a balance bike. The Zulu One fits him perfectly (he's five, and about 41" tall), and the disc brakes are an awesome addition. It does great on dirt, and I can't wait to take him on some longer rides!
Our son loves this bike. It’s close to the ground so it instills confidence he’s already riding down a couple of stairs thanks to the slack geometry. And the 14” wheels are perfect for his 4 year old body. Just a great bike there is nothing else like it.
