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.
These bikes are so much easier for kids to ride than the standard Walmart or even adult name brand kids versions. My two daughters, 5 & 7 went from riding 12” & 20” bikes to the prevelo 3 & 4 - 20” & 24” bikes within minutes. My 5 yr old had barely learned to ride without training wheels a week prior and was hitting trails within a few days of getting her prevelo. The kid focused geometry, lightweight frame, and hand brakes are so important in giving your kid the ability to ride to their potential. Adding the gears is a huge bonus for taking on hills and speed. So glad we’ve got these bikes, thank you prevelo
I purchased this bike last spring for my sons 9th birthday. Light weight with a good gear ratio was my goal for a new bike. I had bought him a Trek for his 7th birthday, but he would never rode it because he couldn’t ride up the smallest of hills in our neighborhood. I finally weighed it one day and realized that it weighed more than my XL 29er full suspension mtn bike...How could that be? So that little Trek was 28.5 pounds, my son weighed 75, thats over a third of his body weight. If that ratio were applied to my bike, my bike would weigh in at 58 pounds?In reality, though it weighs more like 25 lbs and i weigh 170.. so no wonder my son hated riding his bike. If my bike were 58 pounds, it wouldn’t be any fun and would wear me out. After researching most of the big name brands such as Trek Specialized and Cannondale, i realized that they all were excessively too heavy. Front shocks, big knobby tires, look really neat, but those extra items all add dead weight that is absolutely unnesassary for a rider in the 70-100 lb range. Fast forward to today, my son now never hesitates to ride his bike. All the neighbor kids have the “other” heavy bikes, but none of them ride them-ever! My son rides the Alpha Four, all the time. He actually asks me now if i want togo bike riding, that never happened before. We even ride to his school which is 2.8 miles away and mostly up hill. He prides him self on being able to effortlessly ride up the steepest of driveways and those little hills in our subdivision? He flys up them like their not even there. This is what you want, a bike that gets ridden.
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!
