Well built and fun for our 5 year old, just starting bmxer!

Our son has always loved riding. He started with a Costco balance bike.. wishing I knew that SE had balance bikes.. anyways... We went into Robby's bike shop in Stockton, Ca and our son fell in love with this bike.. so much he took it out without even asking! One of the owners was joking with him saying, sorry you stole it so you have to buy it.. His eyes lit up, I had to get it. We took him to Spreckels BMX park in Manteca, CA and he just went to the gate and through the pump track with no fear! He's been racing now for 3 weeks, asking daily, sometimes hourly if he can ride his bike.
Bike is well built and super light. He is so fast on this thing! Don't even think about it.. get it for your kid!
