 ===== BMX =====
-Before Bullmoose bars, mountain bikes were spec'd with handlebars from the motorcycle, road bike and BMX parts bins.  Mountain bikes needed strength and lightness.  BMX gave cheapness and motorcycles the strength.  Many BMX makers shifted to making MTBs with very BMX-like styles.  BMX bars were usually high risers, as the bikes were tiny with 20-24" wheels to make them light weight and nimble (and affordable.)  Note that a typical 1979 Schwinn BMX bike weighed 28.5 pounds, while Ritchey's [[ritchey:start#s1978]] MTB #1 weighed 30 pounds ((See Ritchey specs at the [[https://www.sfomuseum.org/exhibitions/repack-rwanda-origins-evolution-and-global-reach-mountain-bike/gallery#4|SFO Museum]].)).  But Ritchey's bike, at $1400, cost 7x more than a Schwinn BMX at $197. ((See Schwinn ad at: [[https://books.google.com/books?id=Fk7nQv2TpsEC&pg=PT1&lpg=PT1&dq=Schwinn+Scrambler+SX-1000+%22price%22&source=bl&ots=bV3ZcNDSlt&sig=ACfU3U1LnTCB1qKY1hAjpqyGFJUcX0EBzw&hl=en&sa=X&ved=2ahUKEwjJ7oT5yrD6AhXuSjABHUHMDqgQ6AF6BAgoEAM#v=onepage&q=Schwinn%20Scrambler%20SX-1000%20%22price%22&f=false|Boys' Life, April 1979]].))  Even 26" BMX bikes used the same bars, which helped with control and [[https://www.pinkbike.com/news/how-to-pump-your-bike-physics.html|pumping]] rollers and berms.  Or perhaps it's just tradition?

-BMX started in the late 50's in the Netherlands and moved to the US in the 60's in pretty much the same format as it is today: kids racing small, off-road bikes across a short bumpy dirt course.  Mountain biking is similar, but also needs to go up hill (wide gearing and lightness) and faster down hill (larger wheels and strength.)
