FROG 55 IN ACTION

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 because he has been pedaling for 2 years he has no problem riding it. Starting and stopping is a bit of a stretch for him to reach the ground.

FROG 55 SIZING

WHEEL SIZE 20"
RIDER HEIGHT 44" - 54"
RIDER AGE 5 - 8 years
MINIMUM INSEAM*
(Beginner / Experienced Rider)

SEAT HEIGHT 23.7" - 29.0"
STANDOVER HEIGHT 21.4"
BIKE WEIGHT (with Pedals) 18.9 lbs

* Minimum inseam measurement for a child who is large enough to ride this bike. Beginner Riders must reach the ground comfortably and flat footed while straddling the seat, meaning they require a larger minimum inseam. Experienced Riders will be more comfortable extending to their tip toes when straddling the seat. See How to Measure Your Child's Inseam.
Standover Height is measured from the top of the top tube to the ground, rising directly from the front of the chainring.

PRAISE FOR THE FROG 55

Rascal Rides logo

GO FURTHER, LONGER, FASTER, AND MORE EASILY MANEUVER. THEY ARE MORE FUN!

The Frog 55 is a great bike and was designed with a lighter weight intentionally. Our demo rider was just ready to size up to a 20-inch bike and the 55 worked perfectly for her. She was able to immediately pedal off quickly, shift gears easily, navigate other cyclists in the park and had a beaming smile the entire time. Her father mentioned that he appreciated the room for her to grow on the frame, that she was significantly faster, and that she really enjoyed the bright green color, as it is her favorite!

The Frog 55 is a lightweight bike that comes stock with quality components and in a variety of colors to fulfill the dreams of every budding rider. Shifting is a big component of 20” bikes and the 55 will help your little adventure buddy learn to do it efficiently. Frog has provided a bike with a focused attention to detail that makes riding easy and the adventures worthwhile.

ONE OF THE BEST 20 INCH BIKES OUT THERE

If “easy to ride,” “lightweight,” and “great color options” are important criteria for your child’s 20 inch bike, the Frog 52 and Frog 55 should be high on your list. Both 20 inch, 8-speed hybrid bikes, the Frog 52 is slightly smaller than the Frog 55, allowing you to purchase a bike that is the most ideal fit for your growing child.

With trigger shifters, a low, flat handlebar, and knobby, all-terrain tires, these 20 inch Frog Bikes are ideal for confident and adventurous riders who are ready to tackle paved and dirt trails on their first geared bike. Because the Frog 55 is the largest of the 20″ options here, if you’re looking for an aggressive bike with trigger shifters, it is larger than the Prevelo Alpha Three and would offer more room for growth for a taller child.

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!!
