Looking to start your little rider out right?  The Prevelo Alpha One Bike was engineered specifically for small children to be the highest quality, extremely durable, safe and FUN!

This 14" bike is packed with features to help make learning to ride easy.   The low geometry ensures a more stable, balanced and controlled ride.  With easy to reach hand brakes and a lightweight aluminum frame, this bike will be an easy transition from a balance bike to pedaling. The 14" Alpha One fits most 2.5 to 4.5 year olds with a minimum seat height of 15.6".  For increased control and maneuverability by small children, this bicycle is super light at only 14.4 lbs with the coaster brake (or 13.4 lbs with the freewheel option).

  1. Prevelo confidence inspiring low and narrow geometry. Prevelo geometry keeps the rider low, balanced and in control.

Alpha One

Ordering was easy and shipping was fast. I fine tuned the bike when assembling (brake contact, lever placement, etc). But it was pretty usable as it was. I left the pedals off for now as my son is just transitioning from a smaller kick bike. But so far he loves the Alpha One. He wants to ride his “big boy” bike everyday and is already gaining confidence in his speed and cornering due to the stability and control of the Aplha One.
