Vintage bike restoration - 10 euro Koga Miyata from trash to treasure

I believe this 1986 Koga Miyata Adventure I bought was meant for me. It sought me out, somehow knowing I would bring it back from the brink of death and return it to much of its former glory.
After years of service the tired bike’s chain faltered and started skipping. The previous owner didn’t know how to repair it and the bike’s sorry state meant it wasn’t worth the investment at the local bike shop.
And so it was meant for the scrap heap. Luckily for me he changed his mind and put it up for sale for a mere €10 euros as a “fixer upper”. I got flagged with an email and immediately send a message I was willing to buy it. He had already sold it to somebody else. But that guy didn’t show up and I was second in line. Karma, I kid you not.
I had bought a Koga Miyata… well, at least what was left of it.
From the day I bought on August 15th until literally the last day of 2020 I would work on it on and off until it was ready to ride again.
This story is about his journey back to life.
During the eighties a new era in cycling was dawning, which would be known as mountain biking. And 1986 was the first year the Dutch cycling manufacturer Koga Miyata would enter the fray with 2 models: the Koga Miyata Ridgerunner and Terrarunner-E.
They would also introduce the Koga Miyata Adventure that year. The description of this bike is hilarious:
"The Adventure and Adventure-Lady represent the perfect combination between the ideal sit- and user comfort of the Mountain Bike and the positive, light running characteristics of Randonneur cycles. Adventurous bikes for people who prefer a special bike above the more mainstream products. Because the Mountain Bike has limited use in Europe Koga-Miyata felt it needed to build a bike which can still be used by a large audience."
From the 1986 Koga Miyata catalog
Well they got that last part wrong about limited use of mountain bikes. And even though they stated this bike was meant to be used by a large audience I reckon it didn’t sell all that well considering its rarity.

I'm upgrading a 1987 Miyata Valley Runner currently, so this is an awesome video to watch. I love riding that bike all over town.

[@JoaoPaulo-lr6wh]

Respect 🙌

[@lindag.2315]

Nice

[@sebastianokelly2243]

Really good work on a thoroughly useful bike. So many videos here, especially from US, introduce complicated drive chain changes that just aren't necessary: 4 of my 6 bikes are triples and work just fine for what they were designed for. Hats off for the leather saddle upgrade.

Thanks for the compliment. I agree with you, and recommend people to stick with original specs when repairing/restoring drivetrains. It's cheap, simple, and effective (e.g. you don't run into compatibility issues). This is my daily driver and judging from the cassette, it's clear that I use one of the sprockets 90 percent of the time, so why bother turning it into something else than what it was originally designed for?

I found what I believe is a 1969 Miyata "Gentlemen" City bike(?) in amazing condition. I can share a picture with you for your opinion of it's age, model, etc. And congratulations on an amazing restoration project!

Koga Miyata started making bicycles from 1976 onwards. You can find catalogues online.

[@meikyukenthubayashi4181]

Hey can i ask you, ive got frame with name of patch "The Mister Bike " Wich is this old bike was made by The Miyata Work Co-Tokio/Tokyo who's founded by the ex of prisoner of Hitachi Kuni Kasama, named Eisuke Miyata. on steel history it was from 1933-1960. The most uniqe on this bike was on steels because it was made from Gun Sleeve from Miyata Gun Faktor. The most important was on front patch bike which the logo was " M " And it same as every Miyata bike. The different is only the old word trademark with "The Mister Bike". So it's Koga Miyata have a connection historr between my frame " The Mister Bike" And every Miyata bike.
