Hi bob welcome to the site lots of info here . at the home page click on "links" this will give you some places to look. but alot of us use the two following places
http://www.fasteddysports.comhttp://www.newspeedmaster.com/I have used both and at moment waiting for some stuff from eddy to come over as I live over the pond. The bikes have been around a few years now so second hand accessories do come up a fair bit. But you can interchange speedy and america parts so look out for both.hope you find a bargain out there.
