Trying to build my first bike

[motorpsycho]

WOW I realy like that bike I want that same front end on my bike

what size are those tires? what size is that front end?

If you took your fenders off how big of tires could you put on that bike?

Does any one know a keg style tank that I can put in the back under my seat? thats not crazy expensive

the tires and rims are 20". the front tire is a 20 x1.75, and the rear is a 20 x 2.00 cheater slick. The front end is the one that came on the bike, so i have no idea what size it is. If i took the fenders off, i could not get much bigger tires on it. the ones that are on it are as about as big as i can go.
I picked this bike up off craigslist for $40.00 complete. (minus the motor).
I re-painted the frame, chopped the fenders, added the new tires, put on better pedals, added the sissy bar with shocks,added the white metal flake seat, and the headlight.
get yourself a Heinekin mini keg from the liqour store. They are made of aluminum and they will polish up really nice once you remove the painted on Heinekin label. They may be a little bigger than what you're looking for, but it would be easy to turn one into a gas tank.
