Frog 55 Video

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.

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.

Awesome bike, awesome company

The Frog is an excellent bike, and Ready Set Pedal was fantastic- went above and beyond, got the bike out a bit early, great communication, etc- couldn't recommend highly enough.

Awesome Bike

My almost 6 yr old is having a blast on his first geared bike. It didn’t take him long at all to figure out how and when to shift and he is pleased as punch that he can go faster with less effort. We took it to a bike shop to get the brakes adjusted and make sure it was good to go after putting it together and the bike shop guy was impressed with the quality as well.
