David "Tinker" Juarez (born March 4, 1961) is an American former professional BMX and cross-country mountain bike racer.

While he was also known as the "Hollified Flash" after one of his home BMX tracks he used to race at and dominate in the early-1970s,[1] the moniker "Tinker" is a nickname that was coined by his family.

According to his Mother Rose: "We used to say 'Stinker' when he was a baby, everybody thought we were saying 'Tinker"[2] David Juarez is so well known by his nickname "Tinker" many people probably think that is his real first name.

For the sake of consistency and standardization noted professional first are for the first pro races for prize money offered by official BMX sanctioning bodies and not independent track events.

Primary sponsorships can be verified by BMX and MTB press coverage and sponsor's advertisements at the time in question.

Tinker, despite eventually becoming a top pro BMXer in racing and gaining "high airs" in both dirt jumping and vertical freestyle, went ten years without breaking a bone.

Other famous BMX stars both retired and active at the time participated, including Harry Leary, Pete Loncarevich, David Clinton, Stu Thomsen, Eddy and Mike King.
