Getting your kids the right size bike is important and, fortunately, also easy. You just need two pieces of information about your little rider:
Children who are learning are more sensitive to bicycle height than children who already know how to ride a bike. For this reason, our recommendations for bicycle sizing vary slightly based on the experience lever of the rider. The chart below takes into account the fact that experienced riders tend to adapt better to a bike that is slightly larger. For this purpose we categorize young riders as either "Learners" or "Pedalers"

The perfect mix of road warrior and basic all-terrain cruiser, the Alpha Four is built with kid-specific geometry for a precise, comfortable fit.
The Prevelo Alpha series is an exceptional line of bikes for eager young riders. Lightweight with a low-center-of-gravity, the Alphas are fun and easy to ride.
My son has struggled to feel comfortable on a gear shift bike for the last several years. Taking him on a ride was always a struggle with lots of complaining that his legs were tired. He LOVES this bike. He asks to go for rides now. He asks, “can we keep going?” And the only complaints I get now are that the rides are too short!
I thought I'd get a Alpha Four bike for myself, so that my 3 Year old (on an Alpha Two) and I could ride together like "twins". The Alpha Four is only a 24-inch and most adult bikes are 28 inch. My wife laughs at me for riding a kids bike, but my son loves it! Both bikes are fantastic build quality. So easy to assemble - within just minutes. Jacob and his team are amazing. Little items that my son breaks, Jacob replaces them at no charge! BUY a Prevelo Bike. Don't even research anywhere else. This is the best family owned bike company around!
My daughter loves her new Alpha 4 and her bike geek Dad does too. For not that much more than a "standard" kids bike by the major brands Prevelo gets you a well put together machine that's lightweight and well spec'd. I've built many bikes myself over the years and I've found nothing to nitpick. Hats off to team Prevelo!
Hi all, I have been riding bikes for thirty+ years - across a variety of disciplines as well - road, mountain, triathlon... this, along with various sizes of hand-me downs from her older brother, make for a busy garage. When it came time to upgrade my 7yo daughter’s bike, a quick web search brought me to Prevelo Bicycles. Seeing the Alpha Four in person at the Westlake Village showroom sealed the deal. After quickly setting the seat height on the demo bike, my daughter simply climbed aboard and rode away. There really is something to be said about a longish wheelbase, low bottom bracket, low Q-factor (narrow) and shorter crankarms. Jacob let me ride the bike around the parking lot; these bikes are both lightweight and sturdy! Solid frame design coupled with quality components make for a bike she’ll be able to grow with for several years. Yes, these bikes are somewhat more expensive than those you’d find at a big box or dedicated bike shop, but I see it as an investment in my daughter’s riding. She will ride longer and more frequently if the bike is enjoyable. There were some nice touches available to customize the bike, such as handlebar grips and name stickers (both pink) for the seat stays. A third party water bottle and cage round out her new bike. Two thumbs way up for Prevelo!
We are so happy with our purchase. We were looking for a bike that was made specifically for children. We researched other companies that claimed to make bicycles engineered specifically for children but ultimately decided to go with Prevelo, and we couldn’t be happier. One of the reasons we chose Prevelo is because of their esthetic appeal. The bike is beautiful. Our son loves it! We purchased directly from the owner who was kind enough to help our son on his first test ride. As a father himself, he apparently created this company with a self interest. And that interest is a shared interest for all parents looking to invest in a beautiful well made bike geared specifically for kids.
