Features

Class Leading Wide Span Gearing

Tackle the most monsterous of hills with the Microshift Acolyte Super Short derailluer combined with an 11-38T wide span cassette with 345% gear range.

Compared with other brands that use 11-28T cassettes, the Alpha Five offers an additional 90% gear range.

HEIR® Youth Optimized Crank

HEIR® cranks use specific lengths and widths to match young riders pedaling ergonomics. The Dual Alloy Chainguards keep the chain on in all terrain, while protecting the rider's pants from getting caught.

Kid Optimized Cockpit

This is where little riders command their steed. It's decked out with ultra thin grips and short reach brake levers that are optimized for small hands.

Confidence Geometry

The Alpha Five features Prevelo's signature confidence inspiring geometry. Prevelo geometry utilizes a low bottom bracket that lowers the center of gravity of the bike and rider, making for a more agile and confident ride.

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.

Age

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.
