Noise Issues - Clicking, Clunking, or Knocking
BEGIN HERE
Issue resolved.
The noise is being caused by
the movement of the pedal arm
bracket against the roller wheel.
This movement is a normal
function of the machine. A level
of "play" has been built into the
pedal arm / roller wheel to
reduce internal mechanical
stress, and to increase the
longevity of the machine.
Issue resolved.
Wiggle each crank arm and
check for play within the crank
or the connecting arm.
Rotate the cranks and check for
any "gritty" or rough feel in the
bearings.

noise?
