How is the man on the bike described in "Touched"?

The man is described as riding a "jenky" bike down the sidewalk on Cass Street in Detroit (233). "His bike had a normal-size rear tire coupled with a small, even petite, front tire (perhaps rigged from a lawnmower?), a banana seat of the Huffy-circa-1982 variety, sparkling streamers, sparkly handle grips, some bells, and several other accouterments..." (233).
