Our grandson who is 5 ½ has recently has gotten into BMX biking.
The family pooled together and gave his parents money to by him an "official" BMX bike.
I bought this shirt at Walmart boys department. It is safety yellow.
It is even brighter than the picture shows.
His helmet is black and gray with red.
I found this appliqué/embroidery by chance on EmbroideryOcean.com.
It is listed under "racer helmet" .
They had it as a freebie one day and I grabbed it. I made the 5x7.
I believe you can purchase it now for $1.00.
It stitched out beautifully. I changed up the colors to match his helmet.
I hope this help's you if you have that child in your life that loves a bicycle!
