August 2006 marked the most important time in Mike Spinner's life. He entered the Free Flow Tour where he made history by landing the first tailwhip 720 in a competition by an amateur or pro. Spinner was then selected as a Wild Card rider, at the last stop of the 2006 Dew Tour, where he wowed the crown by qualifying first in the BMX Park prelims, his first ever pro contest.
Unfortunately, he took a crash on his opening run of finals. In his first year as a pro he started off stronger than ever, opening the Dew Tour season with a second place finish. He stayed consistent throughout the tour and ended up ranked second in the BMX Park Dew Cup standings.
