Great Bike.

The bike arrived in perfect condition and sooner than expected. Very little assembly was required and the directions were easy to follow. The quality of the bike is so much better than those you buy at a discount store. He loves the bike and I would highly recommend this bike. So glad I made the purchase.

Great starter bike!

From beginning to end it was a great experience. Our daughter loves her bike and had been using a glider bike for a while. She started on the small 20" Guardian bike without pedals for 2 outings then told us she wanted to try with pedal (no training wheels) within 5min she was on her own with no support!! It looks some coaching and experimenting on her part to get started from a complete stop, figure out her balance while starting, but she never fell and was able to confidently negotiate everything with the bike. Great experience so far!!

Amazing purchase

Our daughter is 9 with Down Syndrome and we’ve tried a couple other bikes and she wasn’t able to ride them. We got her this bike for her 9th birthday and she got on and just took off. She is so happy she can independently ride with her siblings. It truly changed her life and was such an awesome moment for our family! So grateful to you guys and your company!!!

light and fun

This bike has made riding so much more fun. Other kids bikes are clunky and nonresponsive. Guardian bikes are light and the breaks are perfectly resonsive.

Training Wheels Compatible

We recommend using the balance bike method when teaching your child to ride a bike, but understand all children learn differently.

Compatible training wheels can be purchased here for our 14", 16", and 20" Bikes.
