I believe you should offer pricing on your site with payment (including shipping) via Paypal for the following:
- Complete bike with tires handlebars, seat pan etc. (with or without engine)
- Complete frame with boardtrack style handlebars, forks, tank (painted or unpainted)
- Complete frame with forks, tank (unpainted, no handlebars)
- Frame with Tank (unpainted)
- Boardtrack style handlebars
- Front forks
- Tires (these look unique)
This is just a suggestion. Some people would be willing to pay the shipping fees if the pricing on the parts are reasonable. I myself have purchased parts from Germany and paid more in shipping to get what I wanted (26" Moped rated tires for example).
