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+.
