Ready for a granddaughter to ride
This bike was very easy to put together as the video shows one exactly how to assemble. Super excited as I’m delivering the bike this weekend during a family reunion in West Virginia’s Canaan Valley. She will be so excited to have hand brakes and gears! I enjoy riding and want each of my grandchildren to get the opportunity to have that same joy as they grow. Thanks guardian for making a great bike.

Exactly as described! Son truly learned to bike in 1 day!
The experience was absolutely AMAZING. My son truly learned how to ride a bike in 1 day, after dabbling with balance bikes and adding pedals for years. He is 7, and he did persevere through a lot of falls and kept getting back up again... and now he wakes up begging to ride his bike. The assembly was amazing, customer service perfect, honestly - thought there would be something that was too good to be true, but this bike and company was everything we read and hoped for! Highly recommend! Likely buying another bike for my younger son, despite having an assortment of balance bikes to choose from.... but this was so much better!

My kid loves it!
We bought this bike for our son as he was outgrowing his 16" Guardian bike. I thought it might take some time to get used to as he is slightly under the height recommendation for this one, but nope he jumped on it and immediately began zooming around. I love how light and easy the Guardian bikes are to ride! My only minor complaint was that the gears were out of whack and needed to be tweaked (which isn't in the assembly instructions), but it was an easy enough fix.

Our second Guardian bike
We just bought our second guardian bike for our 8-yr-old after he outgrew his first. He loves them so much, very solid and durable, precision crafted, smooth ride. We feel especially confident with the braking design, ensuring he can make quick, controlled stops without going over the handle bars with an errant front brake pull. He has been an early rider/pedaler (pedaling before age 5) and we think his Guardian played a role in that - very empowering for him. Thanks for the care put into this!
