It's right for you if...

Your kid has outgrown their old bike, and you want to get them a fun, durable bike that they won't outgrow right away. You don't want to settle for a big box brand, and want a high-quality bike that will keep your kid confident and in control so you don't have to worry. 

The tech you get

Your child will ride confidently with a sturdy Alpha Silver Aluminum frame and dialed components that were designed to better fit kids—an adjustable bar and stem, smaller-diameter grips, a padded adjustable saddle, smaller pedals. Plus, dialed singlespeed gearing that's not too hard or too easy to pedal, and rear coaster brakes with a hand brake for instinctive stopping. 

The final word

This bike is the perfect choice for young riders who want to transition from a little kid bike to a big kid bike, with a simple, quality frame that will keep them upright and smiling while they ride at the park with friends or on the local bike paths with your family.
