===== John Olsen =====


John Olsen of Seattle, WA constructed [[https://en.wikipedia.org/wiki/Mountain_bike_trials|mountain trials bikes]] and only produced a couple of dozen mountain bikes on his own.  However, he designed many other bikes such as the:
  * [[https://www.mtbr.com/threads/r-e-montana-for-richieb-others.474642/|1984 R&E Montaña]] : mountain bike, made in Japan.
  * [[canon:start#s1984|1984 Canondale SM-500]] : a trials worthy mullet bike.
  * [[http://mombatbicycles.com/MOMBAT/Bikes/1987_Raleigh_Edge.html|1987 Raleigh Edge]] : mass produced trials bike.

John Olsen is also a prolific author on all things bike related, including:

  * A regular column, "John Olsen's Trail,"  in Mountain Bike Magazine in the late 80's.
  * A regular column, "Ask Uncle Knobby,"  in Mountain Bike Magazine in the 90's.
  * [[https://www.amazon.com/Adventure-Sports-Mountain-Biking/dp/0811723151|Adventure Sports: Mountain Biking]] : a book on how to have fun on a bike.

<div column 50% #s1982>
----
===== 1982 Olsen =====
Co-created with Joel Jensen of Bellingham, WA.
SunTour Honor derailleur (1978-82), XT M700 brakes (1982-83).
The source article states that this is a 1983, which is quite possible.  However, John started making MTBs in 1982 and this is one his first "4 or 5 frames."  It also has many primitive details, such as only straight tubing for seat and chain stays, horizontal dropouts, BMX forks, & motocross handlebars.
<blockquote>
I never used a front derailleur, and if you saw our trails, you'd know why!
Remember, at this time, there were no strong enough freewheels, no good brakes, no good sealed bearings (that I could afford), and I broke rear derailleurs off like popcorn."

===== 1986+ Strange Bike =====
The bulk of John Olsen's later production has been in making seat-less "strange bikes."  Who needs the weight of a seat when you can't use it?  This example has been upgraded.

<blockquote>
If anybody stole my Strange Bike, I could just walk down to the first corner, kick the guy a few times as he lay on the ground, and take my bike back. Not only did they have no seat, they also had right side front brake levers, the ULTIMATE in theft prevention.
