    A+ all-around

    Excellent experience, fast shipping, great packaging and my son loves his new bike. Mom and Dad are happy with the high quality and fit. His riding confidence immediately increased with this bike after transition from the big box store bike he was riding prior.

    Best Bike Purchase Yet

    We have been on a cadence of buying a new bike each year and we have finally found the bike that fits our son the best! His friend even prefers to ride our Prevelo bike. My son is entered into his first Crit race in two weeks and he looks forward to using his new bike!

    Love these bikes!

    We love our Alpha Two. Not only is it a beautiful looking bike but a really practical bike for the beginning rider. I love that Prevelo puts hand brakes on these bikes because it gets the young rider prepared for the next level. You can tell that the Prevelo team has really thought about every detail and how they would benefit the rider. We are very pleased indeed.

    Quality and Beauty

    Excellent customer service and excellent product. Its a pricey bike for a kid, but the quality and beauty are worth the investment as I expect my son to ride his Alpha Two for the next 2yrs or more. From what I see the resale market for these bikes is also strong so if you are on the fence make sure to factor that in.

    Third Prevelo bike - we are loyal Prevelo owners

    We love Prevelo bikes.  I started my kid on the Alpha Zero, when he was a tiny person, and now he is comfortable, confident, and loves bicycling.  I picked Prevelo because of the reviews, but I loved that it came with a rear brake hand lever - something that hardly any balance bike comes with.   The website is easy to navigate, the customer service is excellent, and the trade up club is wonderful - I feel better about the higher price AND if he grows out of a bike faster than I expect, it is no big deal. We moved from the Alpha Zero to the Alpha One, and now that my son is 4 and a half, he is zooming around on the Alpha Two.    I did a lot of research, and while there are cheaper bikes out there, they aren't equivalent quality, and many of them don't come with both front and rear hand levers.  The way my son rides on dirt paths and down inclines - the hand lever brakes make for a much more precise ride.   If you want your kid to enjoy bicycling, ask to go bicycling instead of sitting around and watching TV, and to be confident and agile on his/her bicycle, then go for a Prevelo bike.
