Prevelo crank lengths are custom sized for each size bike to make sure little riders have optimum pedal ergonomics. And they have ultra-narrow Q-factors to match the narrow hips of young cyclists. If that sounds like technical mumbo jumbo, here's the point - Prevelo cranks will help make small riders more comfortable and efficient on their bike.
The Alpha Four features Prevelo's signature confidence inspiring geometry. Prevelo geometry utilizes a low bottom bracket that lowers the center of gravity of the bike and rider, making for a more agile and confident ride.
9-speed Microshift drive train and 11-36T wide range gearing is the real deal and gives growing riders truly usable and class leading, 327% gear range. Kids are going to be efficient on the flats and have the leverage of low gears available to help make it up tough hills.
This is where little riders command their steed. It's decked out with ultra thin grips and short reach brake levers that are optimized for small hands. The Microshift shifter is operated with two easy to operate thumb levers.

Got the same bike for my 7 year old as I have for my 10 year old (Alpha Four) because we love it so much. My daughter said "this bike is really good. I like this bike better than my old bike because the seat is really comfortable if you're riding a long distance. I think the size is really good and I really like the blue color because it's really shiny" (it IS an awesome blue)! Lightweight, gears are great for her and she figured them out right away and rode up a big hill... All in all an awesome purchase!
Purchased for my 7 year old's birthday. Fit is perfect for her, relatively tall and fairly advanced rider for her age. We've been riding regularly over the last few months and have built up to a couple 10+ mile rides. Components are excellent and she is riding confidently over rolling hills and on occasional gravel. I highly recommend this bike!
Bought this as a birthday present for my 8 year old daughter. She is thrilled with her first geared bike, and couldn't be happier. The bike build and components are very high quality and dealing with customer service was a pleasure.
At 7.5 yrs old our son decided he was open to learning how to ride a bike. After a lot of research, we wanted to buy a bike that was designed for kids, light weight, and could last for the next few yrs of growth. Couldn't be happier with the purchase, delivery, and design of his bike. Followed the "pedals off first" approach to learning and in one week he's confident and riding along side kids that learned at much younger ages. Thanks so much! Great product. Wish we had done the personalized name inscription.
I made the decision to get the alpha 3 a few years ago and never regretted it. One son is now older, the younger one inherited the alpha 3, and I had no questions about getting the alpha 4. The build quality is great, with details such as the kid-centric geometry and internal cable routing. The blue color looks fabulous. I made very few adjustments as I assembled the bike. The alpha 3 required some tweaking, but this one was great. My son was very happy on his 8th birthday. Now both boys can chase their mama while she runs. We have recommended prevelo bikes to many of our friends. Thanks for another great bike.
