Some of the best bikes around!

We just now took it out of the box and assembled it (very easy). My grandson got on it and was up and running almost immediately! While it is almost two inches too tall at the crotch, so far he’s handling it just fine. The bike is so light that he’s already whipping it around like he’s been riding for years ! We’re big fans!!

One happy biker

Excellent customer service... I originally picked a wrong sized bike did my 7 years old, but they helped me get the correct size. Also the bike I wanted was out of stock, they checked the restocking date and I recieved the bike within 2 weeks or so. It is an excellent bike ( frog 52, single speed). My kid loves it. The red color is really pretty with green splatter frogs! It’s a good product that will be passed on to my little one! I would highly recommend this company and do talk to them if something is out of stock online. They might be able to get u a bike sooner than online dates!!

Absolutely one of the best buying experiences a person could have.

Buying from Ready, Set, Pedal couldn't have been easier. Super fast shipping and easy to get ahold of with questions. And this bike is the best. It's super lightweight and so easy for my grandson to ride.
