I had a Huffy 3-speed banana-seat 20" that I've never seen anything like. When I was a kid nobody had one like it and I've yet to find a picture with the same frame -much less a similar paint job.
The bike had twin top tubes -not the ones that swoop down to the downtube and there is a main top tube but JUST two top tubes. They went past the head tube and there were two chromed "tips" that extended out past it.
It had a 3-speed Shimano hub out back with a "console" shifter that sat in between the two top tubes with a T-handle top knob. There was a big plastic chrome-plated console cover over the shifter itself that spanned the top tubes and went nearly all the way from the head tube to the seat tube.
It was your standard banana-seat bike with ape bars, side-pull calipers, and 20" wheels front and back. It came painted in Red with flames on the fenders and chain guard as well as printed into the vinyl banana seat cover. the rear fender had a "flip" at the back and the rear tire was squared off like a car tire or sort of like a dragstrip motorcycle. it turned for crap with that wide flat tire in the back and my dad eventually replaced it after I wore it out on purpose doing skids to kill it.
The bike was Fire Engine LOUD with the silly flames on it and I got made fun of something fierce for it. I hated that flashy flame scheme but looking back on it now it was kind of cool but I just didn't have the panache back then to pull it off. My sister had an almost matching bike with a step-through frame that was blue in a water motif instead of flames. I don't think they were a matched set but perhaps they were but the style of the frames were totally different. I just think my dad thought it was cool that my sister was water and I was fire.
I can't even find a picture of this type of frame with just two top tubes that ran past the seat tube and then became the seatstays almost like on a mixte although they passed the seat tube at the very top and then turned downwards sharply at that point and were regular seat stays not like that Sears bike where they came back all the way to the banana seat rear stays and then curved straight down. This wasn't like that at all.
No pictures -not one from my childhood which is amazing as I rode that bike everywhere for about 10 years. Finally fixed it up and gave it away to friend's kid in the 90's who promptly got it stolen 2 days later because he didn't bother to lock it up.
