I’ve been toying with the idea for a year or two now, and today I placed an order. What brought it back to the front of my mind was a recent thread in JC.
OK, so strictly speaking, it has two wheels, but in all other respects, it’s a unicycle.:o
Being a purist, I have gone for the double fixed, rather than cheating with a fixed/free flip flop hub.
Double fixed, 18/20 which if I remember correctly works out at about 65" and 72", with 165 mm cranks.
I used to ride bicycle many years ago, with the Cyclists Touring Club, Tandem Club, and as a member of the Rough Stuff Fellowhip (this was when mountain bikes were “new fangled”). I had a Mercian (Reynolds 531) frame with 12 speeds, which I converted to 6 speeds, then rode almost everywhere in the same gear, which was around 68 inches. But I was much younger then.
My bike has 46/18 which is 69" using the nominal 27" wheel (68.4" using a 700c x 28). I’m finding that to be a good gear for cruising on the mostly flat bike trail that goes into Seattle. It forces me to stand though for climbs and pull up on the pedals (I’m using clipless). I tried using toe straps and regular shoes but couldn’t pull up on the pedals to muscle myself up some of the Seattle area climbs. So I went with clipless egggbeaters.
I haven’t done much in the fixie mode though. I need to practice the fixie riding on an area of the trail that doesn’t get much traffic. I need to get very comfortable with the fixie mode before using it to go into Seattle. You often need to react suddenly to avoid idiots on the trail. I currently can’t react properly and suddenly like that in fixie mode.
The 46/18 gear lets me easily cruise at 16 to 19 mph. Anything faster than 20 mph gets to be spinning too fast to comfortably sustain. The neat thing is that I figured out the 46/18 to be almost exactly double the Coker rolling diameter. So for the same cadence I go twice as fast on the bike as the Coker.
