When Tom Ritchey introduced bullmoose bars in 1980, they instantly became standard equipment for all new MTBs, defining today what a vintage mtb should look like. The inspiration for this design came after Tom suffered an equipment malfunction while racing down Repack.
MBA: What was your first Repack race like?
Tom Ritchey: I went up there and had kind of a quick yell-out and said, “Whose bike can I borrow?” and I ended up borrowing Wende Cragg's, which basically was just about as classic as any of the bikes that you’ve seen from that kind of Schwinn-heritage category. I hurled myself into the race and down the hill, and—oh, shoot, just a couple of minutes into the race the handlebars rotated. It was pretty much unrideable [laughs], and I ended up getting off, jerking on the handlebars to get them back to straight and got to the bottom. It really wasn’t much of an experience, other than that it initiated my thought process that had to do with the first Bullmoose handlebar and the one-piece system that I knew was needed for a purpose-built, off-road bike.
And so, really, the Repack experience taught me that the handlebars were terrible. The weight of the bikes was terrible. The pickup-truck idea of riding wasn’t who I was. In order for me to do the right thing, I needed to figure out a way to make these truly cross-country bikes. That's what I did. Tom Ritchey, as quoted in Mountain Bike Action
John Finley Scott, an early investor of both Tom Ritchey and of Kelly/Fisher MountainBikes, came up with the name “Bullmoose” because they reminded him of antlers 1) and as a tribute to Teddy Roosevelt.2).

Bullmoose Evolution
- The original Bullmoose bars were either 26“ or 28” wide and weighed 896g if they came with the integrated quill. Ritchey also created a weight saving double wedged quill which simultaneously gripped the stem and the steerer tube.
- Starting in 1983 MountainBikes optionally sold Nitto made fillet brazed bullmoose bars for roughly 1/3 the cost 3)
- Although the Ritchey catalog doesn't state this, starting in 1982, the lower end models such as the Mount Tam, came with TIG welded Nitto bullmoose handlebars.
- After the Ritchey/Kelly/Fisher dissolution, Ritchey referred to bullmoose bars as “Twinstrut” while Fisher MountainBikes continued to use the “bullmoose” name, now appended with a ™ symbol.
- The last vintage MTB in this timeline to use bullmoose bars appears to be the Swiss 1992 Ferraroli Authier. After that, the focus was on making narrow bars light weight out of aluminum, titanium or carbon.
- Nitto recently continued to make the Bullmoose bars and it remains available online at places such as: velo-orange. 28“ wide, 15' sweep, 693g (no quill). Or a fillet brazed Nitto version was available at Rivendell, 26” wide, 30' sweep, 868g (full quill). 4)
1980 Ritchey quill adapter, using a double wedge, allows for the bullmoose stem to firmly grab the steerer tube.

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 1978 MTB #1 weighed 30 pounds 5). But Ritchey's bike, at $1400, cost 7x more than a Schwinn BMX at $197. 6) Even 26” BMX bikes used the same bars, which helped with control and 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.)
Bicycle Motocross (BMX) originally started when children began imitating motocross riders on their bicycles. Old bikes were used on roped off tracks with turns and jumps which gave the pedal powered fanatics a sensation of racing motocross. The number plates on the bicycle and the trophies at the finish line made it feel real. UCI archive
