According to Jim Merz who was with Specialized in the 80s, and designed the next generation of their bikes, it's a Miki. Specialized didn't move any production to Taiwan until later, so it's not a Merida.

I've got an '82 Sequoia frame I'm building up. Serial #M2J44608. Came with a Japan sticker.

Because we get so many requests for helping to ID a bike based on the serial number, we are going to Stickie this wonderful thread.

I did create this as a resource to be used by all members and it was originally allocated stickie status but some administrator removed it.

Yes! Just the information I was looking for! I have a KHS bike and now I finally know what year it was made. Thank you!

These three are Japan made Raleigh bikes.

The first one was purchased by my wife new in 1981. The other two are recent acquisitions.

I believe these were made by Panasonic (National), hence the first digit as "N". I believe the second number indicates year made.

This format is covered under unknown manufacturer N(1). See my comments there.

Need Help Identifying Model and Year of Miyata Bike
 
I recently purchased a vintage Miyata Bike but would like to know the year and model. It's white with black lettering. I have the serial number but I'm not completely positive on the first letter. It's NS90 905713. But the first letter could also be an O. It has Shimano 600 gears, brakes and pedals. On the cross bar it has SplineTripleButted by the seat. and on the crossbar by the handlebars it has 414 in green and white. And CRMO on the forks. Can you help me identify the year and model please? Any help would be appreciated. Thanks

T-Mar 10-30-17 10:44 AM

Brady30, this one is easy, as the Miyata 414 was a one year only model - 1990. It sounds like yours has been modified, as these were catalogued as coming with SunTour Blaze components. I would have expected the serial number to start with an 'S'.

Hey T-Mar. Thanks For the info. I got it last week and I'm trying to learn all I can about it.

T-Mar 10-31-17 05:25 AM

Brady 30, FYI, the Miyata 414 was 10th in a line of 12 road bicycles. The original MSRP was $380 US. The original Blaze components were SunTour's 2nd from the bottom of the line road group at the time. The 414 would be considered a sports bicycle, on the cusp of entry level and mid-range. It was geared like an entry level recreational/touring model but had slightly more aggressive geometry, though not as aggressive as a racing model. It was targeted at club riders and novice triathletes. You can find all the specs in the 1990 Miyata catalogue here: Miyata Bicycle Catalogs: Miyata Catalog 1990 (100 Year Special Edition)

I'd appreciate it if you double check on the serial number. My database has several other Miyata STB models from 1990 and they all follow the standard format. TIA.

This is from a late 80's Taiwan made Raleigh Pursuit, just finished converting this into a single cog 2-speed.

Are you sure there isn't a leading "M"? It looks like there could be one, just stamped more lightly.

Got a 1987 centurion sport dlx

Maybe you all know this but here at vintage-trek.com is a lot of information about dating components, many of which are Asian. (Information, and/or misinformation. I have no idea, though I'm sure it's all well-intentioned.

Incidentally, I have a Suntour front derailleur that looks newish by Suntour standards and is stamped "JD". The "J" takes it just off the scale explained in that web page, but by extrapolation it would be 1993, which seems reasonable to me. (Suntour's history is rather confusing.)

Univega Alpina Uno Vintage?
 
4 Attachment(s)
I'm a newb to this forum, so forgive me if I ask something that's been asked previously. I have a question based on your info though. I have a white & black marbled (similiar to spider web paint) Univega Alpina Uno, the serial number is M9A11556. How can I determine the year of manufacture? Pics included with components.

2cam16 01-28-18 12:06 PM

I'll leave the deciphering to the more knowledgeable people here, but judging by the components and paint job, that's most likely a 90's era bike.

T-Mar 01-28-18 12:14 PM

The Univega Alpina Uno in post #46 is a 1989 model. Given the era,it was most likely manufactured by Merida of Taiwan, but a similar format was used by Miki of Japan. Check for a country of origin decal, to be certain.

birdie6463 01-28-18 01:28 PM

:thumb: Thank you. I checked for a COO sticker but didn't see one anywhere. It's taken over two weeks of searching on the web to finally find you. Thank you again T-Mar

More Info Alpina Uno S/N
 
Could you tell me the significance of the characters that led you to the correct answer?

T-Mar 01-30-18 07:35 AM

Birdie6463, read post #1, referring to the Merida & Miki entries. The only thing you have to figure out yourself is the decade for the year indicator. In this, we know it's 1980s based on the Mountain LX components, which were only manufactured in the very late 1980s.

Great LOL

wrk101 02-17-18 07:30 PM

Just another data point, I picked up a 1972+/- Volkscycle 100, the one made in Japan. Its the nicer model, pretty much all generation 1 Dura Ace.

Serial number is BS01542M

Spottted a clean Araya for 60.00 bucks. A kid snapped it up while I was looking around. Snapped a pic of the serial number in the event T-mar is collecting data...

@T-Mar
I have 2 Yokota serial numbers for you. The first is a Yokota ElCapitan B90038856, the second is a mixte road bike (unknown model) 89051508.

Thank you T-Mar for a wonderful reference ... but now I am going to have to turn my Bianchi Incline upside down again. I know for a fact I bought it new in 1989 from Any Mountain. I read the S/N to be H4A50763 but that can’t be right! The cable guide somewhat covers the S/N ... will report back when the Bianchi and I are in the same place and I can take another look.

dnkjones 02-28-18 12:08 PM

I will offer a data point...we bought our Nishiki Cascade MTB in 1990 and the S/N is W89103641. Would I be correct to interpret that our bike was built by Kawamura and the S/N translates W US market 89 year built 103641 sequence number?

I don't think that I currently have any Incline in the database but the ones I've seen had the 1988-1989 decal scheme (i.e small triangle before the Bianch name). That is a Hodaka serial number format and they were a known source during this period.
