This is in HOLLAND 1954! Family van Heugten (Former world champion Motocross sicecar rider Ton van Heugten is in the picture.)Maybe the Dutch didn’t start it but never saw an older picture with guys riding BMX bikes, and we even have footage on film to proof it. Thanks for posting this Kim. Also like the picture with the Hamor Head t-shirt BMX’er, I used to sell their shirts in Europe a long time ago.
