Lubrication
Remove any accumulated dirt from the freewheel with a brush
and a degreaser. Disassembly of the freewheel is a complicated
procedure requiring special tools, and should be left to a
specialist. Apply oil to the freewheel whenever you lubricate the
chain, taking care to wipe off any excess.
COASTER HUB
Many BMX style and other children's bicycles are fitted with a
coaster hub brake in the rear wheel. This type of brake offers
the advantages of reliability and easy operation. The brake is
operated by applying back pedal pressure and allows the rider
to 'coast' without pedaling, if desired. There are several models
of coaster hubs available, and the internal mechanisms are very
complex. They require infrequent attention as far as lubrica-
tion, adjustment or replacement of internal parts; if needed, this
should be left to a specialist.
Keep the coaster hub sprocket clean and oil it along with the chain.
Make sure the brake arm is correctly attached to
the chainstay with the brake arm clip. The brake
will not operate otherwise.
