+===== Koski Overview =====
+After building up many klunkers from his family's [[https://mmbhof.org/the-koski-familys-cove-bike-shop/|Cove Bike Shop]] in Tiburon, CA, and then helping his brother Don Koski and Mert Lawwill launch the [[lawwill:start|Lawwill-Knight Pro-Cruiser]] in 1979, Erik Koski launched the Trailmaster on his own. Only 55 to perhaps 75 were produced over three years ((see production notes)). Koski resurrected the brand in 1998 to co-produce a Titanium version with Steve Potts (([[https://www.mtb-kataloge.de/Bikekataloge/PDF/Mountain_Transport/Moutain_Transport.pdf|Mountain Transport Catalog]])).  See also: [[https://mmbhof.org/erik-koski/|mmbhof]] and [[http://mombatbicycles.com/MOMBAT/BikeHistoryPages/Koski.html|mombat]].

+===== One more pic =====
+Not enough credit is given to Erik Koski in the history books. Joe Breeze used Koski forks for the first set of Breezers. The Cove Bike shop printed the very first mountain bike catalog in 1980. Koski mountain bike components were sold for decades.

+==== Production Notes ====
+<WRAP #prod1 />
+[1].  As Trailmaster #2 was 1980, 1980 is a good guess as the start date. See: [[https://www.sfomuseum.org/exhibitions/repack-rwanda-origins-evolution-and-global-reach-mountain-bike/detail#4|SFO Museum]]
+<WRAP #prod2 />
+[2]. Less than 100 Trailmasters ever built. [[http://fattireflyer.com/|Fat Tire Flyer]], page 117.

+  * Or perhaps only 55? [[https://www.mtbr.com/threads/30-years-riding-the-same-mountain-bike.642880/|mtbr.com]]
+<WRAP #prod3 />
+[3]. End of production in 1982? [[http://mombatbicycles.com/MOMBAT/BikeHistoryPages/Koski.html|Mombat Koski Catalog ]]
