The 14" Alpha One is the smallest pedal bike in the Prevelo lineup and fits most 3 to 4.5 year olds. It's packed with features to get little riders off to the right start, including:
  1. Prevelo confidence inspiring low and narrow geometry. Prevelo geometry keeps the rider low, balanced and in control.
  2. Lightweight 6061 aluminum frame with custom formed tubing.
  3. Lightweight aluminum alloy fork with chromoly steerer.
  4. Tektro front and rear v-brakes with small reach brake levers.
  5. Rear coaster brake (removable with optional freewheel kit).
  6. Front hub with low profile rounded hex bolts and no harsh edged nuts for little legs to knock against.
  7. Three piece crank with squared taper cartridge bearing bottom bracket and ultra narrow Q factor.
  8. Double chain wheel guard.
  9. Custom made cranks. All Prevelo cranks are sized specifically for each model bike, down to the millimeter.
  10. 95% assembled. Just install the handlebar, seatpost and pedals.

From the tiny saddle to the custom 85mm-long cranks, everything on the Alpha One has been thought-through with the dedication and passion I normally see reserved for bikes costing thousands more.

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!

Nothing compares

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.

Perfect fit! Great design! He won’t put it down!

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!

Love this bike

This bike is both beautiful and functional! It looks like a motorcycle! I love that it's different from anything I've ever seen. It's also perfectly engineered for kids. My son has gotten comfortable on it quickly! The service truly is amazing. I love their personal touch and the Prevelo team has treated us like family! I've already purchased my second one. The Alpha Zero for my younger son. He loves it too!

The Alpha One is "PERFECTION"

Jacob @ Prevelo Bikes is phenomenal! This attention to detail in the build of this little bicycle is amazing and his customer support was awesome! I got my son his first balance bike at 2 yrs old for Christmas in 2016. By August, he has mastered it and I felt it was time to start looking into his first pedal bike. After weeks of research (that's how I am) I discovered Prevelo and placed my order for my son's first pedal bike (Alpha One) for his 3rd birthday in early November 2017. The build quality was perfect and assembly a breeze. At first, we had our son ride the bike without pedals so he could get used to the size of the bike since it was bigger than his balance bike. By the 4th day of practicing, he pedaled on his own for the first time. The look on his face was PRICELESS. The lower center of gravity and his ability to put his feet flat on the ground from the seated position is confidence-inspiring for my son. Our whole experience with the Alpha One, from the website, the ordering, the shipping time, packaging, assembly, the quality and customer support has been EXCEPTIONAL. If I could I would rate this product 6 Stars. Because my son is 3.5 yrs old now, I will be looking to order an Alpha Two for him soon since I enrolled in the Trade-Up Program that Prevelo Bikes offers. I can't thank Jacob and his team @ Prevelo Bikes enough for creating and delivering the PERFECT bicycle for my son. Thank you again Jacob and you'll be seeing my son and I sometime this year for his Alpha Two and some TACOS.
