Here's a chopper I built up this summer:
Features:
-21 speed Shimano DX componentry
-2.2" flame slick on the back
-2.2" bmx ramp slick on the front
-Custom Fork/stem combo made by me at the Pedal Play shop
-custom dual lever rear V-brake
-layback post with adapter shim
-pilsner holder
-hidden stash pipe
-lots of black paint.
I think it turned out pretty well for my first 'chopper'.
Its really fun to ride, going super slow its nice and stable, and at speed its the same.
The turning circle is pretty small if you plant your foot down too.
