Assembly
All Frog 55 bikes arrive 90% assembled. All you need to do is install the pedals, seat post, handlebars and front wheel. If you decide you want the optional mud guards on your bike, these will need to be installed also.
Our professional bike technician looks over every bike before it ships and switches the hand brakes to be standard for the US (rear on the right, front on the left).
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.

Beautiful Bike with strong build quality and materials
So far so good, my daughter loves her new Frof55 Spotty!

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.
