Alpha Four

Introduction

The 24" Alpha Four is the perfect bike for 7 to 11 year for use on either paved or dirt paths.

‍

Hill Conquering Gear Range

The Microshift Acolyte Super Short Derailleur allows the Alpha Series bikes to use an 11-38t cassette. This gives 90% more gear range than other comparable bikes.

‍

Kid Friendly Shifting

Microshift is the only drivetrain maker to focus on kids sized shifters. Easy-to-reach triggers and ultra-light shifting action make this the #1 shifter for kids.

‍

Kid Sized Control Center

Short stems, handlebars sized to match shoulder width, easy-to-reach brakes, and a kid-friendly shifter. All features that give the rider control of their steed.

‍

Confidence Inspiring Geometry

Low standover allowing young riders to get on a bigger wheel earlier. Bigger wheels roll faster, offer more traction, and roll over obstacles with less effort. Upright seating position with just enough weight over the front of the bike to maintain control and balance. A low center of gravity that's designed to keep the riders weight "in" the bike, rather than on top. Short chainstays keep the bike agile, while a slack front end keeps things stable at all speeds.

HEIR® Kid 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.
