Size Guide and Model Comparison


  • 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.

  • 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.

  • 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.

  • 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.Learn more about teaching kids to ride with The Balance Method™.

  • 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.

  • THRU-TUBE™ Frame

    The unique THRU-TUBEis designed to keep riders low, confident and agile. It unlocks class-leading low seat height and seat height range, and improves pedaling ergonomics while keeping the rider's feet close to the ground.

Alpha One


The Alpha One is the smallest pedal bike in the Prevelo lineup and is the perfect starting point for the youngest cyclists—easy to learn on and the ideal first bike, with short cranks that fit little legs perfectly and a THRU-TUBE frame design that offers class-leading low saddle height.

It's packed with features to get little riders off to the right start, including:
  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 with small reach brake levers.
  5. Rear coaster brake (removable with optional freewheel kit).
  6. Front hub with low profile rounded hex bolts and no harsh edged nuts for little legs to knock against.
  7. Three piece crank with squared taper cartridge bearing bottom bracket and ultra narrow Q factor.
  8. Custom made cranks. All Prevelo cranks are sized specifically for each model bike, down to the millimeter.
  9. 95% assembled. Just install the handlebar, seatpost and pedals.
