PRAISE FOR THE FROG 52

THIS IS A GREAT BIKE!

It’s light, nimble, and super fast. I couldn’t believe how fast my son could ride on it. This was his first hand brake/gear bike, and he picked up the gears and brakes very easy – they were easy to use and intuitive. He gained confidence on the new bike, and on more challenging terrain, quickly. The bike performed well on dirt and gravel roads, which is where we used it most of the time. We also used it on more narrow two-track (which sometimes is more like singletrack) (on the Osprey Falls Road), where it navigated rocks and uneven terrain easily. My son definitely put it through it’s paces – and it performed very well in all the ways I would expect with an active, adventurous, rambunctious kid.

Lightweight High Quality Bike

I spent a long tome deliberating when to upgrade my sons pedal bike and which to get. Chris and Cheri were extremely helpful in working with us and giving us the information we needed to make the right purchase at the right time. My son transitioned easily to this bike. He has learned the shifting easily and really appreciates the lightweight frame for the hike a bikes!

Buy from this place!!

Bike is lovely but the experience of buying is really why you want to go here. Chris was super responsive to all my questions and kept me informed of shipping schedule. It's never just about the item, it always about the customer service, especially when bikes are so hard to come by. We bought online. I only wish we were local. This place is really heads and shoulders above the rest. On a scale of 1-10, a 10+.
