Clydesdales/Athenas (200+ lb / 91+ kg) - Where to find retro bike...

...I want a bike I had when I was a kid. You know, the one with the bannana seat, sissy bar on tha back the went up about 3 ft higher then the seat, the high rise handle bars, maybe even the orange flag on the back. I just want one to putz around the neighborhood with the kids or town with and don't know where to start looking for something like that.

I have an orange flag in my garage if it helps. Here ya go

Check garage sales, craigslist, pawn shops, Salvation Army stores, etc.......

They are out there, because I have seen them, but some people think they are some great piece of art and want more than they cost new.

You'll need to buy the sissy bar seperately:

+1 to all above advice - thrift shops, salvatiion army, craigslist... the bikes are out there waiting to be ridden.

You could also consider buying a modern cruiser style bike like the ones made by Electra (http://www.electrabike.com) (and others). They are not exactly the banana bikes of yor, but ooze style (at least I think it is style :D) and are a whole lot more comfortable for an adult to ride than a kid's bike, even just for cruising the neighborhood.

You could also consider scrounging the dump and recycling depot for banana seats and cruiser frames and make something unique.

I have seen a few people add ape hangers, banana seat and sissy bar to new cruisers to get that old muscle bike look and actually have a bike that fits better than an old 20".

+1 Craigs List. Also, post a wanted to buy on Craigs List. Also use one of the Craigs List search tools and be willing to travel a distance to obtain it.
