    Wonderful bike

    My 6 year old loves the bike, the 20 inch large needs a handle bar that goes up higher though

    Great bike

    The shipping was super fast! We received the bike within 2 days. Assembly was quick and easy. The only problem is the bike is to small. I did the measurements but unfortunately it's to small for my son.

    Hi Sarah, While we're sorry to hear the bike didn't fit properly, we can definitely help out with getting another size! We allow returns within one year of the delivery date of your bike. To get started, how tall is your child? We want to be sure the second bike is a perfect fit! Along with your child's height, can you also share their leg length measurement? How to measure 1. Have your child stand tall, with their feet shoulder width apart (shoes on) 2. Place any size book up between your child's legs as high as it can go (we want to measure to the point where they will be sitting on the seat; this is different than measuring pant inseam) 3. Measure from the ground to the top of the book to get their inseam measurement. Thanks! We look forward to hearing back. Best, Laura @Guardian Bikes

    My kid is loving riding their bike!

    Sturdy bike. Easy shipping. Easy assembly. I like all the geometric science you all use (or at least market;))

    Broken :/

    The process of putting together the bike was great with the videos until I went to attach the handlebars. I unscrewed the bolt to be able to insert the handlebars and now it will not tighten. Not sure if something is broken but this has significantly delayed us using the bike. I have sat there trying to figure this out for way too long and now the bike is sitting waiting to be put together in the garage.

    The Best Bikes at the Best Price

    What is Total Value?

    We believe great bikes shouldn’t break the bank. When we say you’re saving money, we mean it—no inflated prices, no gimmicky markdowns.

    Our expert team sources top-quality components and frames and assemble every bike right here in our USA factory.

    By manufacturing domestically and managing our own factory, we avoid high tariffs and retail markups, saving you hundreds of dollars on premium bikes without sacrificing quality.

    How Do We Calculate Value?

    We keep it straightforward: we compare the actual prices of three comparable bikes with similar quality and components. Our "Total Value" is always at or below their average price, ensuring you get the best deal every time.
