Anatomy of an Alpha Two



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.

      Little ripper

      Loving the bike! My son is already telling me that he is doing tricks just like Danny Macaskill! Would love to have a little more direction on hot to fit kids bikes (i.e. Feet flat on ground or toes only).

      So happy to hear that your little Danny Macaskill is enjoying his Alpha Two.  Thank you for the constructive feedback about providing instructions for kids bike fit.  We thrive on feedback like this.  We have a new illustrated guide on how to fit a kids bike.  Check it out here:

      Alpha Two Review

      My son is 3 1/2 w/ an inseam of about 16 1/2". He was an aggressive balance bike rider and has been ready for a pedal bike for a while. I wanted a 16" bike for him but couldn't find any that would fit and be easy to learn on. This was the only 16" that I could find that fit him (he could put his feet down easily) and was high quality. When I took him for his first ride, all it took was a little push and he was riding away. At the pump track, you can see the difference in geometry vs. most other bikes like this. The wheelbase is much longer, the riding position lower, and the fork geometry more forgiving. The slack head angle has already saved him a couple of times. As for ease of assembly, I had it together in about fifteen minutes, including swapping out the longer seat post. The only thing I've adjusted is the brake lever positioning. No complaints so far but we're only a couple weeks in.

      Great Light Bike

      My daughter and I really like the bike. It's light, good components, and fits her really well.

      Great kids bike

      This is a great bike. Well designed and made- my 4 year old son was able to transition to this bike from his 12'' easily. He calls it his "speed bike" because it is so much easier for him to pedal and ride fast. We went on a 4 mile bike ride with him around San Diego Bay and he led the whole time! I'm really glad we chose this bike.
