The 24" Alpha Four offers an NEW 9-speed Microshift drive train. The 11-36T wide range gearing is the real deal and gives growing riders truly usable gear range.
Prevelo crank lengths are custom sized for each size bike to make sure little riders have optimum pedal ergonomics. And they have ultra-narrow Q-factors to match the narrow hips of young cyclists. If that sounds like technical mumbo jumbo, here's the point - Prevelo cranks will help make small riders more comfortable and efficient on their bike.
Confidence Inspiring Geometry
The Alpha Four 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.
9 Speed Microshift Drivetrain with Wide Span Gearing
9-speed Microshift drive train and 11-36T wide range gearing is the real deal and gives growing riders truly usable and class leading, 327% gear range. Kids are going to be efficient on the flats and have the leverage of low gears available to help make it up tough hills.
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. The Microshift shifter is operated with two easy to operate thumb levers.

- NEW Microshift 9-speed drivetrain. 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.
- 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.
- Replaceable derailleur hanger. If the derailleur takes a hard hit, the hanger can be replaced without repair to the frame.
- 11-36T wide span gearing gives riders plenty of range to spin up tough hills.
