Gerrit Does has been instrumental getting an international organisation of the the ground called the I.BMX.F. , now integrated into the UCI. Louis Vrijdag was instrumental integrating I.BMX.F. into the UCI which took about 6 years to realise all together.
Gerrit has been involved in BMX up and till 1998 (since 1974 meaning 25 years of involvement) and Louis Vrijdag up and till 1999 (since 1978 meaning 21 years of involvement) working for the KNWU (National Cycling Fed.) and the UCI (president BMX committee UCI).
