I have a GB4 29" frame. I’ve used it as a road racing uni and a light MUni. But now I don’t do 29" road riding any more, and after many iterations, I still haven’t had much luck with the MUni version. Now I’m using a pair of Black Widow cranks, which feel like they bend (and flex back) with each hard crank. But it’s a beautiful red frame.
Here are some other custom cycles I have:
Prehistoric Trials uni made by Chris Reeder, but with square-taper axle and the bent cranks it came with, so I don't use it.
Wilder MUni. Not custom perhaps, but hand made.
Also my carbon fiber MUni frame by Roger Davies, with Thudbuster Uni-Pivot seat post and reinforced Miyata air seat.
From Hamilton's Bike Shop in Wichita, Kansas, a 5-footer from the 1970s. I bought it from a professional performer who wasn't using it anymore.
From the Unicycle Factory, the next several, starting with my 9-footer. It has an articulated step on the back that stops the wheel, so you can freemount it. With a little practice.
My 45" big wheel.
My tiny 12" wheel with super-short frame and post.
My old Miyata Freestyle frame, which was shortened for a 20" wheel (they didn't come that way) and has seat tube all they way up to the seat.
My 24" racing frame, also a longneck custom job.
I used to have a skinny, super-light track unicycle with hollow axle, skinny tire, etc. It was stolen at Unicon X in China.
I ride my Telford every week, and thank Geoffrey Faraghan every time. I use a 24 by 3 inch Nokian tire mostly, but still have a 700c road tire that gets a bit of use.
I’m not sure if I’d count my Blizzard as a ‘classic’ though. Whilst Joe Rowing doesn’t make frames any more, UDC still list them as being for sale (well, the 20" version at least).
If anything, my muni is more of a classic, as it was a one-off by UDC (see link at the bottom of that page).
In terms of real famous classic unicycles, I guess Zach Baldwins titanium trials unicycle from Defect must be pretty high on the list. That is now (well, the frame at least) owned by Sponge, so no need to speculate on the whereabouts of it… But we can speculate on how long it’ll be before it’s back up and running
I don’t know if it even occurred to me to ask. I figured, what are the police going to do? We’re looking for a unicycle, in the middle of the biggest gathering of unicycles that ever took place in China. Yes, it mostly looks like all those other ones, but with a few minor variations…
