Loaded with Features Obsessively Thought Out for Kids

Durable Rear Stays and Reverse Mounted Rear V-Brake

Kids are going to put their bikes through the ringer, so the Alpha Zero is built kid tough with robust rear stays. And the reverse mounted v-brake lets riders start learning braking right at the beginning.

Quick Adjust Seat Height

The quick release seat post clamp makes it easy to adjust the seat height without tools.

Kid Friendly Hubs

The hubs are equipped with rounded axle bolts that minimize hard edges. And because kids are going to run their bikes through the muck, the hubs have rubber seals to keep out dirt and grime.

Kid Optimized Cockpit

This is where the little rider commands their steed. It's decked out with ultra small diameter grips and a short reach brake lever that is optimized for small hands.



Size Guide

Prevelo Bike Sizing

Getting your kids the right size bike is important and, fortunately, also easy. You just need two pieces of information about your little rider:

  • Inseam
  • Rider Experience

Measuring Inseam

  1. Have the rider stand against a wall, hold a book between their legs so that it is firmly against their crotch  and the wall (the same place their bicycle seat will be).
  2. Measure the distance from the floor to the top of the book.

Rider Experience

Children who are learning are more sensitive to bicycle height than children who already know how to ride a bike. If the rider is new we recommend erring on the side of a smaller bike.  If the rider is experienced and confident, it is OK to err on the side of a larger bike.


We include ride age as guidance for our bikes as a quick reference. But because riders of the same age can have very different sizes, inseam is a more reliable size indicator than age.

      Instant Fun!

      My daughter had been on another wood bike and not doing to well. Within a day she was coasting feet up on this thing. Love it! My 20 month old just likes to sit on it as if its a Harley.


      Amazing Company

      We decided my son needed a bike on 4th of July. The owner welcomed us into his office to test one out, let my 20 month old ride around the back warehouse and answered all of our questions! The bike is amazing, super light and easy for my little guy to pick up and maneuver. Customer service is above expectation. I love that they're a local company to me, and so easily available and ready to help!

      Great little bike

      Bike was shipped 2 weeks earlier than I was told. It is a Christmas present for my grandson, so he hasn't seen or ridden it yet. Quality appears excellent.
