Thank God
Nice to buy a kids bike that isn't a pile of junk. No comic book characters on this bike, but I'll take that all day. This bike is actually built to last and I won't spend more time pumping up cheap tires or fixing other parts falling off. Thanks for making a decent product Guardian!

It’s ok to take your time learning!
Our daughter just turned 6 and is switching off training wheels and is able to balance the 15 seconds as recommended on her new Guardian bik. She is also not in a rush to do it all in a day. She is beginning to notice the pressure and some judgement from others to be riding without training wheels at this age so this has been a great lesson in it being fine to feel frustrated and you don’t have to do everything like everyone else. She enjoys riding a bike and that’s all that matters, but we’re grateful to find a bike like Guardian to make the transition easy and fun. Thanks!

Great bike!
Our daughter got the hang of the pedals on her 14” bike right before her 5th birthday. I used the bike sizer based on her height and purchased the 20” small bike for her based on that recommendation. I thought it was a pretty big jump up for her size-wise, but she hopped on it and pedaled away immediately. She is so proud of her new big bike! Arrived quickly and in time for her birthday and was so easy to assemble! Definitely recommend!

Love this bike
Great experience overall. Setup was easy and our daughter learned how to ride in 2 days. Training wheels are a thing of the past. This is so much more Intuitive. Love it!

Perfect for 5 year old girl
This bike is amazing. It was very simple to put together and very well built. The braking system is well designed and easy to learn how to use. My daughter is 5. She just learned how to ride without training wheels on her small Disney princess 12” bike. The transition from it to the 20” small guardian bike was flawless and painless. She picked right up on it and has not looked back. I would strongly recommend buying this bike for your little ones.
