Hi ive been a member here for a long time I got started on 2 projects i have owned the playbike since i was a kid. and i also have a beach cruiser. Well on to the questions. Can the frame be welded on i want to weld up the headbadge holes and maybe make some frame braces out of metal rod and or sheet metal. I also was thinking this bike would look great with a 3 speed Can this be done ? what parts would i need to use even if i need to modify them. i need to change the rims to new ones anyway the originals are pitted and rusty. The back tire and rim will be changed to a slick. Can i find one on an auction site ? or here ? The last question ...for now is how wide of a slick will fit on it i know the schwynn chopper tires out now are too fat. Thanks for any help I can post pics of what i have to work with if that would help. i'll have to figure out rim and tire sizes also and post them here. Thanks again Rob.
