There is a time when you just have to give up trying to understand and just go with it.

Many of these elaborate bikes belong to members of the Good Times Detroit Lowrider Club. From what I understand in talking with one of their members, this group is basically a lowrider car club whose members own custom, vintage autos that can be raised or lowered by the flip of a switch. The young bike owners are members, and once they reach legal driving age, the car guys take them under their wings and help them build out a classic lowrider car.  So basically, they are immersed into the lowrider car culture and ownership through bike customization beginning at an early age.
