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.
Kids are going to put their bikes through the ringer, so Prevelo bikes are built kid tough with robust BOXT rear chainstays and seat stays, and BMX track style forged dropouts that shroud the rear axle.
The Alpha One 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.
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.
This is where little riders command these steed. It's decked out with ultra small diameter grips and short reach brake levers that are optimized for small hands.
A low minimum seat height and dropped top tube help accomodate the smallest riders.

United StatesThe Alpha One is absolutely perfect for our 5 year old son! He transitioned from riding a balance bike to his Alpha One on the first day we got it and we couldn’t be happier! We are extremely grateful for the Prevelo team shipping the bike to us about one month before we were expecting it and for providing a military discount on top of that! We will definitely be recommending Prevelo to our friends and family in the future for their high quality products and top notch customer service!
CanadaWe ordered an Alpha One for our son's fourth birthday. He has been riding a balance bike for two years but had never used anything with pedals before. Half an hour after he got the bike, he was starting to put his feet up on the pedals and do a couple of rotations, and after an hour he was pedaling for several seconds. After that he was unstoppable, and 5 days after he got the bike, he went on a 8km ride! He also figured out the hand brakes without a problem. He says that it's the best present he's ever gotten! This bike is very high quality construction, nice and light, and fits him perfectly. He's low to the ground and we can tell that he feels comfortable and not "tippy". And, throughout our purchase, Jacob's customer service was incredible! He was friendly and helpful with sizing advice, and sent out the bike as quickly as he could so that it was here by my son's birthday.
I know a bit about bikes. After a childhood love affair with bikes led to a semi-pro cycling career after high school and university I opened and ran a successful bike shop for 12 years. When my daughter was born I left the bike industry but bikes never left me. When I had to buy my daughter her first bike :-) only the best would do. Abi's Prevelo is long and stable, the fork angle is perfect and the 14"wheels are like 29ers for a 3yo and yet the standover is lower than any competitor. The bike is light, easy to handle and every part is quality material. Specially conceived Q-factor, crank arm length, handlebar diameter and brake lever reach. There is nothing else on the market that comes close. Thank you, Jacob and company!
The Alpha One is our family's second Prevelo. Our older son got an Alpha Two for his 4th birthday and we got the Alpha One for younger brother's 3rd birthday. Following the how to ride tips on the Prevelo blog, our new 3 year old was riding in a couple practice sessions. A month later he's tearing up a pump track and just rode for 6 miles. The Alpha One makes riding easier and therefore much more enjoyable. A few thoughts if you're considering the Alpha One: - Seat height matters. The low center of gravity makes a world of difference when learning to ride. Can't possibly overemphasize how important that is. - Freewheel is a must. You have to have a freewheel and hand brakes to make a good transition from a balance bike. The occasional stop in pedaling or accidental backwards pedal is a non-issue with a freewheel but will cause a spill with a coaster brake. - Resist the "grow into it temptation." By measurement our 3yr old was right at the low end of the Alpha Two range, which was very tempting. Jacob suggested the Alpha One and I'm so glad that's what we got. The frame and geometry are sized appropriately and set our son up for success. Measure it's worth by the amount of miles and smiles, not years. - Looking online doesn't do these bikes justice. Neighbors and co-worker dads are blown away at the difference in quality between the Prevelo and bike shop or department store bikes. The build quality and components are top notch. - If what you want is backordered, it's worth the wait. I waited a month after our kid's birthday for a backordered Prevelo - there's nothing else comparable with such a low seat height. Sure, he didn't have the bike with the balloon on it on his birthday, but that's how much I value the quality of the Prevelo and I'd do it again.
Our 2.5 year old switched from his strider to this bike in less than a week. I don’t think this would have been possible without such a great design. The geometry is great for building his confidence- he can reach the ground because the seat really drops low. I almost went with the Alpha 2, but I’m glad we got the Alpha 1. He’ll grow out of it faster, but he has a perfect fitting bike now, which is important to learn on and gain confidence. The bike is also really light, and looks great too. I was also really impressed that his little two year old hands can actually reach the kid size brake levers. Customer service was great, and we’ll be coming back for more when he grows!
