Here is a 6 year old riding the Frog 55.  This child is 47" tall with an inseam of 18.75".  He is on the small side for this bike, but has been pedaling for 2 years so has no problem riding it.

I recommend this product

Great knowledge & service, great lightweight bike

I bought my 7 year old son a Frog 5 20" bike and it's an excellent product; lightweight, high quality, lots of great features and stylish. I called Ready, Set, Pedal to get some advice and discuss the pro's and con's of the different bikes that were on my shortlist. The people I spoke with were very knowledgeable and took the time to answer my questions and discuss my purchase. I decided to go with the Frog and they processed and despatched the order quickly and efficiently. Great company.

Pretty good all-around bike

It’s lightweight and worked pretty well for a year. Great for commuting to school. My kid rides single track/MTB trails and it worked fine, but the tires are skinny and the frame more upright than most kids he rode with. The back brakes had some issues after a few months and our bike mechanic explained it was an inexpensive brake (probably like many kids’ bikes) and the spring mechanism inside was going. I had hoped to get 2 seasons out of it but given the overall experience probably will upgrade to a more mountain bike style bike.

Great bike!

My 6yo *loves* this bike! She figured out the gears right away and can go so much faster than on her 16” bike. The assembly was really well explained in videos and pamphlet. Very happy about our purchase!!

Excellent bike

From the ordering to the shipping to the putting together, the whole experience was awesome! We love these bikes (this is our second one), and we will be back.
