The 20" Alpha Three is our smallest geared bike. The NEW 9-speed Microshift drive train and 11-36T wide range gearing is the real deal and gives growing riders truly usable gear range.
Kid Optimized CrankPrevelo 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.
BOXT Rear Stays and Forged Dropouts
Kids are going to put their bikes through the ringer, so Prevelo bikes are built kid tough with robust BOXT rear chainstays and seat stays, and BMX track style forged dropouts that shroud the rear axle.
Confidence Inspiring Geometry
The Alpha One 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.
Kid Friendly Hubs
The hubs are equipped with rounded axle bolts that minimize hard edges. And because kids are going to run their bikes through muck, the hubs have rubber seals to keep out dirt and grime.
Kid Optimized Cockpit
This is where little riders command these steed. It's decked out with ultra small diameter grips and short reach brake levers that are optimized for small hands.
Low Standover Height
A low minimum seat height and dropped top tube help accomodate the smallest riders.

- 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.
