Loaded with Features Obsessively Thought Out for Kids


The Alpha One's unique frame is designed to keep riders low, confident and agile. The unique THRU-TUBEunlocks class leading low seat height and seat height range, and improves pedaling ergonomics while keeping the rider's feet close to the ground.

HEIR Frame Hugger™ Saddle

The unique interface between the seat post and saddle allow the Frame Hugger saddle to get ultra low to accommodate small riders, while providing an ultra-wide height adjustment range for growing riders.

Ultra Adjustable Seat Height

The proprietary THRU-TUBE frame design and HEIR Frame Hugger saddle combine to give the Alpha One class leading seat height range. The seat height can be adjusted from 14.5 in to 19.7 in. And the quick release seat clamp means that adjusting seat height is a quick tool free task.

Kids Optimized Crank and Removable Pedals

The HEIR cranks are custom sized for each bike size to make sure little riders have optimum pedal ergonomics. The ultra-narrow Q-factors matches narrow hips of young cyclists. Technical mumbo jumbo translation: more comfort and efficiency for small riders. The pedals can be removed to help little riders learn balance.

Kid Optimized Cockpit

This is where the little rider commands their steed. It's decked out with ultra small diameter grips and short reach brake levers that are optimized for small hands.

Forged Dropouts and Kid Friendly Hubs

Kid put their bikes through the ringer. Prevelo bikes are built kid tough with robust BMX track style forged dropouts that shroud the rear axle. Think durable and made to last. 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.
