Hi I have a B F Goodrich Challenger girls bike that I am trying to date. On the bottom bracket is stamped:
MO. 213x7
486076. Any info would be appreciated

MO is Murray (of Ohio), and the only X in my unreliable Murray list is 1964. But in 64 the numbers were on the dropout, so yours is an older bike than 1964.
Like ingola said, a a pic will ID the maker (BF Goodrich was just a brand name) and narrow down what year it was made.

Do you only have the one bike?
 
Here's an early 60's model.

I am going to try to get some pics this week and maybe it will help with identification. Just the one bike for now. Thanks

I am no specialist in American bikes, but I do not recall ever seeing quite this model, and it looks quite complete!
 
It's built by Murray.

Serial # stamped on the BB = pre-1959
MO = Murray Ohio (Mfr.)
X7 = BF Goodrich (which matches the head badge)
213 = model or style/color? unsure
Found a 1950 Murray built Mercury with same rack.
Found a 1950 Murray built Mercury with same tank and crank style.
Missing ubiquitous pointy rear dropout
Double fork crown

I'm stuck on 1950, but can't confirm that. It was fun looking and checking around.

Thank you. Any ideas on approximate value?
 
That's a Murray chainring, the earlier ones don't have the inner part slotted like the more common ones we see.

I agree with about 1950, but the chainguard looks like a later one, late 50's to early 60's. It's original looking at the patina and color though. The rack is definitely early 50's Murray. I'll look around to see if I can find a match to that bike.

Unfortunately, even in mint condition with original tires and everything, there still isn't a market for classic American women's bikes. Only someone wanting that exact bike would pay any money for it. The parts would bring in a lot more dough, as most of the parts are interchangeable with the men's models.

Thanks, just curious if any value. I only paid $15 and just had to clean and lube the chain, air up the tires, and turn the handlebar stem around.

At $15 you did good. Sometimes the sum of the parts is worth more than the bike.
Same here for this bike. That rack is worth more than what you paid to someone out
there looking for one. No doubt. Those original grips. Nice. But I'm the type to clean
it and grease it up and take it for a spin. Try and find someone that might appreciate
it for what it is. A nice classic, well made in the USA bicycle.

And I agree with Wildcat about that style chain guard. It's on a few later year bikes.
The color and patina match, so I'm sure it's factory. If you look at the lines, that skinny
guard makes sense for that frame too. It shows off more of that (would be) polished
chrome chainring (definitely Murray) and the design makes the eagle look like it's really
taking off! Very creative. Maybe this was the prototype chainguard that was picked up
a few years later that saved them steel and gave that "new modern" look too. I mean,
they already had the dies hanging on the wall, ready to punch them out. Only the
serial numbers can tell us the year it was built. I don't have that information.

I like the detail of the matching blue trim around the bottom of the white seat. Class.
It plays conversely to the white pinstripes on the blue fenders.
You know that every time the girl walked up to that bike and saw that eagle she thought,
"Let's fly baby!" :thumbsup:
 
Trying to turn a profit on bikes like this is a lost cause. The value is in the enjoyment. If it was me, I would clean polish wax and regrease everything . Make an investment in new spokes, rims, and tires. Makes for a nice project. You might have to spend $125 or so for tires, rims, and spokes. In the end you will have a really cool bike that will be maintenance free for 25 years or so.
