Prevelo Bike Sizing

Getting your kids the right size bike is important and, fortunately, also easy. You just need two pieces of information about your little rider:

  • Inseam
  • Rider Experience

Measuring Inseam

  1. Have the rider stand against a wall, hold a book between their legs so that it is firmly against their crotch (the same place their bicycle seat will be).
  2. Measure the distance from the floor to the top of the book.

Rider Experience

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"

  • Learner: riders who either have not yet learned to ride a pedal bike, or are still frequently putting their feet on the ground while riding.
  • Pedaler: riders who can ride confidently and only put their feet down to stop.

    Exceptional--all around!

    Hi Jacob & the Prevelo Bikes Team, Before I begin, I must apologize for not providing any feedback when we purchased our first Prevelo for our now 3.5-year-old. We LOVE your bikes. I can't recall how I stumbled upon your site, but I have to admit I am beyond grateful and thrilled. We bought the Prevelo One for our oldest daughter, Izzy. She turned three in December and she learned to ride in less than two months. Now, she is cruising and cutting corners like mad(wo)man. Our second daughter, Jacqui turned two on July 16. She watches Izzy with awe, thus we decided to get her a balance bike to get her going. No surprise, she loved it! Your bikes are made with such precision that the height, length, and reach is perfect for their tiny little bodies. We recently had our third child, a boy, this April. (If you are keeping score, yes, we have a 3.5-year-old, a two-year-old, and a 3-month-old.) So expect, the Beverage family to be valued customers for years to come. We appreciate all the thought and work you guys put in making your bikes. We absolutely love everything about them; the ease in putting it together, the craftsmanship, the quality and the sleek design. You guys totally nailed! Hope you all are having an awesome summer! All the best, the Beverage family (Steve, Rochelle, Izzy, Jacqui and Harrison)

    Amazing Company

    We decided my son needed a bike on 4th of July. The owner welcomed us into his office to test one out, let my 20 month old ride around the back warehouse and answered all of our questions! The bike is amazing, super light and easy for my little guy to pick up and maneuver. Customer service is above expectation. I love that they're a local company to me, and so easily available and ready to help!

    Brilliant . The bike is well made and aesthetically pleasing . My daughter is in love with it , she has just turned 3 and this was her birthday present , she has had it for 3 weeks now and it goes everywhere . The bike is light weight but stable to ride and she has grasped the idea nmvery quickly . I love the extras - her name and the matching bell . So far the bike has been a great choice and I wouldn’t hesitate to recommend . In terms of customer service , the company have been lovely to work with . I live in Australia and even thought it’s not a listed shipping company I emailed and the company said they could ship it and gave me a cost straight away . Customer service was excellent , prompt responses , no hassle and regular correspondence with tracking until the bike was delivered . The bike was also packaged well for delivery . It was such a positive experierie I am hoping to buy another bike for my older daughter later in the year . Thank you for providing an easy service with delivery of a lovely product which is a pleasure to watch my daughter ride .

    Great design!!!

    I got this balance bike for my son when he was 18 months old. The first months, he was still a bit too small so he didn't want to use it. But when he hit 24 months... BAM! He was ready. He jumped on it and got it right away. For the past 4 months, he's been going full speed with his feet in the air. He's just a joy to watch! The Alpha Zero is a great balance bike and Jacob gives a very good customer service.
