Quick delivery

I was surprised they arrived so quickly. They are Christmas gifts for the grandkids so they are hiding in the garage waiting to be assembled.

Awesome Bike!

We upgraded my tall 5 year old son from the 16 in. Fast delivery and easy setup. He loves the gears and it fits him well! We love the brake system and quality especially compared to other kid bikes on the market. So glad we found Guardian!

Best Customer Service EVER!

There was a confusion with a color and without question, they sent a new bike and had the other one picked up with no questions. Would order over and over just based on the customer service. BUT also my daughter loves the bike and its perfect!
