What the Press Says about the Alpha Three

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.

The Bike Dads

For parents interested in introducing gears at an early age, and for kids who have already mastered pedaling and bike handling, the Prevelo Alpha Three is the ideal 20 inch bike.

Rascal Rides

Exceptional - 5 Stars

Exceptional from frame to wheels, brakes to handlebars, the Prevelo Alpha Three is the ultimate ride for young, adventurous riders.

Two Wheeling Tots

Thank the gods, my 7-year-old got her new Alpha Three right out of the box (which came with her name already emblazoned on the shiny steed and took me about ten minutes to assemble), and immediately overcame whatever was previously holding her back. The combination of lighter weight, more optimal kid geometry, and a freewheel hub seemed to do the trick, and alleviate my previous feelings of failing as a father.

Alpha Three

  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.
