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 bike

My kid is happy. He was able to transition to it very easily from a 14 inch Woom. The mudguards aren’t super great but honestly he doesn’t really need them. Ready Set Pedal was great to work with during this COVID summer of bike scarcity.

Great bike for 6 year old

I bought this bike for my 6 year olds birthday. She immediately got on and started riding and was happy that she finally had gears to go fast. It took my husband 3 hours to put it together though. No instructions were included in the box and the instructions on the website were kind of piecemeal. It would be great if there was an instructional video available from the company for this bike. I would buy again but can’t give 5 stars because it was a pain to put together.

Great Bike, Great Store!

My daughter loves her bike. This is her second Frog, and it was an easy adjustment form the 16" wheel to the 20". Ready, Set, Pedal was excellent as always.
