Size Guide

Size Guide and Model Comparison


  • 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 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. 

  • 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.

  • Confidence Inspiring Geometry

    Low standover allows 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 rider's 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. 

  • 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. 

What the Press Says about the Alpha Four

Exceptional - 5 Stars

The perfect mix of road warrior and basic all-terrain cruiser, the Alpha Four is built with kid-specific geometry for a precise, comfortable fit.....The Prevelo Alpha series is an exceptional line of bikes for eager young riders. Lightweight with a low-center-of-gravity, the Alphas are fun and easy to ride.

Two Wheeling Tots

The Alpha Series from Prevelo are neighborhood bikes that punch above their intended use. The geometry lends itself to ripping up trails as much as it does flying around the cul-de-sac. Everything is spot on from the tires, to the brakes to the handlebars.

Alpha Four

From $712.00 $821.00
  1. Prevelo confidence inspiring low and narrow geometry. Prevelo geometry keeps the rider low, balanced and in control.
  2. Lightweight 6061 aluminum frame with custom formed tubing.
  3. Lightweight aluminum alloy fork with alloy steerer.
  4. Front and rear v-brakes.
  5. Lightweight Allen head front and rear wheel skewers for secure wheel installation.
  6. Three piece crank with squared taper cartridge bearing bottom bracket and ultra narrow Q factor.
  7. Custom made cranks. All Prevelo cranks are sized specifically for each model bike, down to the millimeter.
  8. NEW Microshift 8-speed drivetrain with wide-span 11-38T gearing. Uses a shorter pulley cage without comprising gear ratio width. Because kids’ bikes have small wheel diameters, rear derailleurs on kids bikes hang low and close to the ground. The Prevelo Alpha bikes use smaller cage derailleurs to keep things high and away from the ground.
  9. Microshift Trigger Shifters. Small hands have a hard time using twist shifters. We use reliable silky smooth thumb shifters. They are easy for small hands to operate, and operate just like shifters on high performance bikes.
  10. 95% assembled. Just install the handlebar, seatpost, front wheel and pedals.
